Conversion efficiency: up to 95% (input voltage and current; output voltage and current affect conversion efficiency)

Short circuit protection: fuses

Module size: 73 * 51mm

Weight: 270g

Detailed description:

1. The product uses sufficient materials and adopts a customized radiator. The specifications are: the thickness of the radiator base plate is 5mm, the tooth height is 21mm, the length is 85mm, and the width is 63mm. The booster plate is fixed above the radiator, and the rational design is integrated with the radiator and booster plate, making it convenient for users to use directly. Long screws can be used to fix it directly.

2. The inductor magnetic ring adopts a 27mm iron silicon aluminum magnetic ring, a 1mm double wire wound inductor, a high-quality filtering capacitor, with one input of 1000uF63V electrolytic capacitor and two outputs of 470uF100V electrolytic capacitors. The boost output power quality is better, and the onboard power switch and power operation indicator light are equipped with voltage regulation and current limiting adjustment potentiometers, making the output more convenient. The output voltage and current can be adjusted at any time. The input and output use 8500 wiring terminals, Strong current capability ensures long-term reliable operation.

Application scope:

1. DIY an adjustable output vehicle power supply, which only requires a 12V power supply to be connected to the input. The output voltage can be freely and continuously adjusted (14V-80V), but the output voltage cannot be lower than the input voltage.

2. Universal car laptop power supply. Connect the input to a 12V power supply and adjust the output to the voltage required for the laptop to work.

3. Booster charger, can use a 12V power supply to charge batteries above 12V, such as 24V batteries, and the charging current can be adjusted.

4. To power electronic devices, as long as the voltage is adjusted to the required voltage and the current does not exceed the rated current, it can work normally.

5. System front-end power supply. When working on a project, the input voltage is 12V-18V, and the system board requires a power supply of around 24V with a high power output. The power of a regular DC-DC module is too small, so this module can work directly without debugging, easily achieving high efficiency and high power boost.

 

Example of module application:

1. Input voltage 12V current 8.73A, boost output voltage 20V current 5.0A, module efficiency of about 86%, stable output voltage and current

2. Input voltage 54V current 13.5A, output 58V current 12A, use 5 Ω 1Kw resistor as load test, efficiency is 95%

3. Module output 965W test diagram, using a 5 Ω 1Kw resistor as the load test

Special note:

The module has a constant voltage and current function, but because it is a non isolated boost mode, its characteristic constant current range is related to the input and output voltage and load,

Constant current range: For battery charging, we recommend that the input voltage of the module is less than the discharge cut-off voltage of the battery, and the output is equal to the charging cut-off voltage of the battery. Otherwise, we cannot guarantee a constant current range. Using resistive loads to test the constant current range will be relatively narrow. The minimum current is equal to the input voltage divided by the load impedance, and the maximum current is equal to the output voltage divided by the load impedance. Therefore, the constant current value has a maximum and minimum value, which is not as large as you want or as small as you want

Suggestions for battery charging: adjust the output voltage to the battery charging cut-off voltage, then adjust the current limiting potentiometer to the minimum position, connect the battery, connect the ammeter, and adjust the current to your needs. It should be noted that the charging process decreases as the battery voltage increases.

Special attention:

1. During use, please follow the principle of first powering on the module before connecting to the load, which is particularly important in high-power loads

2. The input voltage should be stable, especially for some low voltage (12V) input power sources. When connected to a load, the voltage will drop below 10V, which can easily cause power transistor breakdown.

3. Try to avoid the upper and lower limits of input voltage as much as possible to avoid module damage caused by voltage fluctuations

4. After burning the fuse, do not connect the fuse again for power on testing. The cause must be ruled out before power on. Generally, burning the fuse is due to the breakdown of the power transistor

5. It is strictly prohibited to use short circuited loads to regulate current

6. Two or more modules cannot be used in parallel for both input and output, otherwise the current limiting function will fail

7. The voltage difference between input and output is not suitable, otherwise the constant current function cannot be guaranteed. For example, some friends use a 12V battery to boost to 14V to charge the 12V battery, which will burn the fuse if the current is too high.

8. The normal voltage of the module is normal, and some laptops cannot be charged and used. This is a non quality issue because current computers have recognition functions and may refuse to use power supplies from non original chargers.

 8V~36V to 12V~80V    

Product Introduction:

Large heat sink design (length 85MM * width 62MM * height 64MM), and black oxidation treatment (black oxidation heat dissipation effect is excellent). Supports a wide input voltage of 12-36V, adjustable output voltage of 13-80V, and ultra-low input output voltage difference.

Taobao exclusively launches the output constant current method, don't miss it! (At present, the current regulation of similar modules on Taobao can only adjust the input current, so this can only be used for input overcurrent protection and cannot control the output current. Only when the output current is adjustable is the true constant current.)

Module parameters:

Module Name: 1200W Boost Constant Current Module

Module nature: Non isolated boost module (BOOST)

Input voltage: 8-36V

Input current: 20A (When it comes to a true 20A input, many sellers on Taobao almost falsely mark it. One inductor and one MOS power transistor can reach 20A, and I don't believe it even if I die)

Static working current: 15mA (when 12V rises to 20V, the higher the output voltage, the higher the static current will increase)

Output voltage: 13-80V continuously adjustable

13-80V adjustable

Output current: 20A MAX If it exceeds 10A, please strengthen heat dissipation (related to input and output pressure differences, the larger the pressure difference, the smaller the output current)

Constant current range: maximum 20A

Input power:=input voltage * 20A, for example: input 12V * 20A=240W, input 24V * 20A=480W, input 36V * 10A=720W,

If higher power is required, two modules can be used in parallel. For example, if the output is 30A, two modules can be used in parallel, and the current of each module can be adjusted to 15A.

Working temperature: -40~+85 degrees (please strengthen heat dissipation when the ambient temperature is too high)

Working frequency: 150KHz

Overcurrent protection: With current limiting power current regulation, the output current can be adjusted to limit. If the current exceeds the limit value, the output current will be automatically reduced to the minimum value of 5A, which may vary depending on the nature of the load

Short circuit protection: With (input 20A fuse) dual short circuit protection, it is safer to use.

Input reverse protection: none, (if necessary, please input a diode in series)

Output anti backflow: Yes, there is no need to add anti backflow diodes when charging.

Installation method: 4*3mm screws

Wiring method: Welding free output of wiring terminals

Module size: 85mm in length, 63mm in width, and 64mm in height

Application scope:

1. DIY is a regulated power supply that can input 12V and output adjustable from 12-80V.

2. To power your electronic devices, you can set the output value according to your system voltage.

3. As a car power supply, it can power your laptop, PDA, or various digital products.

4. DIY a high-power laptop mobile power supply: paired with a large capacity 12V lithium battery pack, your laptop can light up wherever you go.

5. Solar panel voltage stabilization.

6. Charge batteries, lithium batteries, etc.

7. Drive high-power LED lights.

Operating instructions:

 Input voltage range selection: Factory default is 12-36V input

Output voltage and current regulation method:

1. Adjust output voltage: Adjust the CV potentiometer and set the output voltage to the voltage value you need based on your battery or LED. For example, adjusting the voltage of 10 LED strings to 37V and adjusting the voltage of four battery strings to 55V.

2. Adjust output current: Set the CC potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, after discharging the battery, connect it to the output and adjust CC to the current you need. (When using it for charging, be sure to use the discharged battery to adjust it accurately, because the more remaining battery power, the smaller the charging current.) Please do not adjust the current through short circuits. The circuit structure of the voltage boosting module cannot be adjusted through short circuits.

3. Overcurrent regulation: designed for output short circuit protection, meaning that when the output short circuit exceeds the set short circuit limit current, the power supply will turn off and output a minimum value of 5A, which varies depending on the load, thus protecting the power module and electrical equipment from damage. Adjustment method: First, set the current of the protection point, and protect it if it is 8A. Use the method of adjusting the output current to 8A, and then adjust the "overcurrent regulation" CL potentiometer (counterclockwise rotation) to suddenly reduce the output current to the minimum value. The overcurrent point at some point is 8A. (Note that if the current at the protection point is lower than the current required by the device, the power supply will be protected. It is recommended to rotate clockwise for about 30 turns to the maximum if overcurrent protection is not needed.)

4. Imported 27mm large iron silicon aluminum magnetic ring, thickened all copper enameled wire with double winding, thickened aluminum heat sink to lower the heating of the entire module. Input two 470uF/100V electrolytic capacitors, output three 470uF/100V low resistance electrolytic capacitors, and output lower ripple. The vertical design of the inductor is more stable, with minimal interference. The replaceable fuse provides more reliable dual protection. The overall setting is very reasonable, and the structural design is very meticulous.

 

 

10V~60V to 12V~80V

Compared to the old model, the circuit structure has been optimized, making the power supply work more stably. At the same time, input anti reverse connection (using 150A MOS anti reverse) and input low battery (low voltage) protection have been added, and the low battery protection voltage can be adjusted from 9-50V to adapt to various batteries. When using a battery for power supply, do not worry about damaging the power module and battery when the battery runs low.

Installation method: 4 3mm copper pillars

Wiring method: Wiring terminals (please use high current pure copper wire)

Module size: 130mm in length, 52mm in width, and 53mm in height 

Usage

Input low battery protection adjustment:

Low battery protection is mainly aimed at preventing over discharge of the battery when the input power is the battery, and damaging the power module and battery when the battery voltage is too low. For example, setting low battery protection for 12V batteries. Connect a 10V voltage to the input terminal of the power module and use a flat screwdriver to adjust RV1 (increase the clockwise protection voltage and decrease the counterclockwise protection voltage) until the UVLO light is on. At this time, the low battery protection voltage is 10V. When the battery voltage drops to 10V, the power module does not rise (the input voltage is equal to the output voltage)

Output voltage regulation:

When the power is turned on and unloaded, use a flat screwdriver to adjust the output terminal "V-ADJ" potentiometer (as indicated in the figure above) clockwise to increase and counterclockwise to decrease. Due to the large output capacitor capacity, the response will be slower when adjusting the output voltage from high voltage to low voltage. The amplitude of the instrument adjustment is smaller.

Output current regulation:

Turn the "A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to low, connect the LED, and turn the "A-ADJ" potentiometer clockwise to the current you need. For battery charging, after discharging the battery, connect it to the output and adjust RV2 to the current you need. When charging, be sure to use the discharged battery for accurate adjustment, because the more remaining battery power, the lower the charging current.

Power Description:

The maximum output power of the module is determined by the input power. As the maximum input current of this power supply is 20A, the output power is related to the input voltage. The higher the input voltage, the greater the power. Due to limited heat dissipation area, please add a 12V fan for heat dissipation when the input voltage exceeds 10A or the output current reaches 10.

Output power=input voltage * 20A

For example, when inputting 12V * 20A=240W, the maximum power output is 240W

For example: Input 24V * 20A=480W, that is, when inputting 24V, the power is 480W

For example: Input 36V * 20A=720W, that is, when inputting 36V, the maximum power is 720W

Notes:

1. The module has a constant voltage and current function, but because it is a non isolated boost mode, its characteristic constant current range is related to the input and output voltage and load,

2. Constant current range: For battery charging, we recommend that the input voltage of the module is less than the discharge cut-off voltage of the battery, and the output is equal to the charging cut-off voltage of the battery. Otherwise, we cannot guarantee a constant current range. Using resistive loads to test the constant current range will be relatively narrow. The minimum current is equal to the input voltage divided by the load impedance, and the maximum current is equal to the output voltage divided by the load impedance. Therefore, the constant current value has a maximum and minimum value, which is not as large as you want or as small as you want

3. Suggestions for battery charging: adjust the output voltage to the battery charging cut-off voltage, then adjust the current limiting potentiometer to the minimum position, connect the battery, connect the ammeter, and adjust the current to your needs. It should be noted that the charging process decreases as the battery voltage increases.

4. The voltage of the input power supply must be above 10V.

5. When using a switch mode power supply as the input power supply, first connect the input power supply with no load and adjust the voltage. Then go and connect the load. (It is necessary to ensure that the switch power supply is always working), or adjust the voltage without load first, then disconnect the switch power supply and connect the load. Connect the switch power supply and power module with the switch power on. Because the switching power supply has a ramp up time when turned on. When the voltage is below 10V, the chip is not yet working. It is easy to break down the MOSFET.

6. When used in constant current mode, it is necessary to ensure that the fixed voltage is higher than the input voltage. (For example, when the input voltage of the power supply is 12V and the no-load output voltage is 15V, connect a 3.2V LED light. This situation is not allowed. It is recommended to connect at least 4 LED lights in series.)

Special attention:

1. During use, please follow the principle of first powering on the module before connecting to the load, which is particularly important in high-power loads

2. The input voltage should be stable, especially for some low voltage (12V) input power sources. When connected to a load, the voltage will drop below 10V, which can easily cause power transistor breakdown.

3. Try to avoid the upper and lower limits of input voltage as much as possible to avoid module damage caused by voltage fluctuations

4. After burning the fuse, do not connect the fuse again for power on testing. The cause must be ruled out before power on. Generally, burning the fuse is due to the breakdown of the power transistor

5. It is strictly prohibited to adjust the current through short-circuit output, and the circuit structure of the boost module cannot be adjusted through short-circuit

6. Two or more modules cannot be used in parallel for both input and output, otherwise the current limiting function will fail

7. The voltage difference between input and output is not suitable, otherwise the constant current function cannot be guaranteed. For example, some friends use a 12V battery to boost to 14V to charge the 12V battery, which will burn the fuse if the current is too high.

8. The normal voltage of the module is normal, and some laptops cannot be charged and used. This is a non quality issue because current computers have recognition functions and may refuse to use power supplies from non original chargers.

 

10V~60V to 13V~90V  

Product Introduction:

1. Using wing shaped heat dissipation has excellent heat dissipation effect and a larger output power (the power can reach around 1800W when 48V input and fan are added).

2. Temperature controlled fan, combined with hydraulic bearing fan, achieves a very good balance in noise and heat dissipation. When the load is light, the fan does not rotate. When the load is heavy and the temperature reaches around 60 degrees, the fan automatically turns on. It can effectively reduce noise and extend lifespan.

3. The insulation board of the main power tube is made of high-grade aluminum oxide, with a thermal conductivity 10 times that of ordinary insulation pads.

4. Adopting large packaged power transistors, with a large power margin and good dynamic response.

5. Double large-sized iron silicon aluminum magnetic rings, using four 1.2-purity copper enameled wires in parallel, with low heat generation and high efficiency.

6. Newly designed with a conversion efficiency of up to 98.1% (details can be found in the efficiency conversion curve in the data manual below).

7. Brand 3296W multi turn potentiometer, with high adjustment accuracy and small drift.

8. Kang copper wire output current sampling, constant current stable with small temperature drift.

9. The undervoltage protection is adjustable, which can effectively protect various batteries and can also be used for solar cells.

10. Equipped with constant current function, it can be used for boosting the voltage of electric scooters, charging batteries, and so on.

11. Input three 20A fuses in parallel to protect against the risk of accidental short circuits in the output.

12. Three indicator lights: undervoltage, overcurrent, power indicator, and clear working status at a glance.

13. High frequency capacitors are used for input and output, with low output ripple, low heat generation, and long lifespan.

14. MLCC ceramic capacitors have been added to the input and output, resulting in a significant reduction in output ripple, which is approximately 100 millivolts at 48V to 72V 4A.

16. The default is 10-16V for undervoltage protection, and it is necessary to adjust the 104 potentiometer (reverse by about 10 turns) to achieve this

Application scope:

1800W is designed by us for lead-acid batteries, lithium batteries, solar cells, or power boosters to boost and charge electric vehicles, and it is very powerful.

1. For example, the original battery of an electric vehicle can be boosted from 48V to 60V to supply power to the electric vehicle, which can improve its speed and acceleration.

2. To charge your electric bike, (1) For example, if you have a 12V or 24 idle battery in your hand, you can use this boost power to charge the original battery, which is like a power bank for an electric vehicle. (2) At the same time, you can also connect solar cells, wind energy, generators, and other power sources to boost the original battery and increase the electric vehicle's endurance

3. You can increase the battery voltage to make the electric vehicle run faster, and the voltage should not exceed 10V.

Operation Guide:

Voltage regulation:

When the power is turned on and unloaded, use a flat screwdriver to adjust the output terminal "V-ADJ" potentiometer (as indicated in the figure below) clockwise to increase and counterclockwise to decrease. Due to the large output capacitor capacity, the response will be slower when adjusting the output voltage from high voltage to low voltage. The amplitude of the instrument adjustment is smaller. (The default output voltage is set to around 60V for shipment. If you need us to adjust other voltage values, please explain or leave a message.)

Current regulation:

Turn the "CC A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to, connect the LED battery and other loads, and turn the "CC A-ADJ" potentiometer clockwise to the current you need. For battery charging, after discharging the battery, connect it to the output and adjust the CC A-ADJ to the current you need. When using it for charging, be sure to use the discharged battery for accurate adjustment, because the more remaining battery charge, the lower the charging current. The default output power is set to 10A for shipment. If you need us to adjust the current value, please provide instructions or leave a message. Do not adjust the current by short circuit output, and the circuit structure of the boost module cannot be adjusted by short circuit.

Input low battery protection adjustment:

Low battery protection is mainly aimed at preventing over discharge of the battery when the input power is a battery. Low voltage protection should also be set when the battery voltage is too low to damage the power module and when the battery input is a switching power supply.

Method 1: For example, set a 12V battery low battery protection. Connect an 11V voltage to the input terminal of the power module and use a flat screwdriver to adjust RV1 (increase the clockwise protection voltage value and decrease the counterclockwise protection voltage value) until the UVLO light is on. At this time, the low battery protection voltage is 11V. When the battery voltage drops to 11V, the power module does not rise (the input voltage is equal to the output voltage). Only when the input voltage is higher than 11V, the power supply will recover and start boosting.

Method 2: Connect the input battery or switch power supply. If the UVLO light on the board is off, turn the RV1 potentiometer clockwise to turn on the UVLO light. After turning it on, turn it clockwise for two more turns. If the UVLO light is on, turn the RV1 potentiometer counterclockwise to turn off the UVLO light. After turning it off, turn it two more turns. (Adapted to 10V-45V voltage)

 

Notes:

(1) The positive and negative poles of the output cannot be reversed or short circuited.

(2) If used as a boost drive power supply for electric vehicles, the input voltage must be above 24V. The power of electric vehicles is less than 500W. Because the electric vehicle motor is an inductive load, the current will be very high at the moment of starting and when going uphill. Sufficient power margin must be left.

(3) When using batteries, switching power supplies, solar panels, generators, etc. as input sources, it is necessary to lower the battery protection, otherwise it will damage the battery and power supply

(4) When working at high current and full load for a long time, attention should be paid to ventilation and heat dissipation to extend the service life of this power supply.

(5) The module can only increase voltage but not decrease voltage, and cannot provide power to electrical equipment below the input voltage, such as charging a 12V battery with a 24V battery or charging capacitors. Power lED below input voltage

(6) Please do not work at full load for a long time. When working continuously, please leave a 20% margin and pay attention to ventilation and heat dissipation

Special note:

The module has a constant voltage and current function, but because it is a non isolated boost mode, its characteristic constant current range is related to the input and output voltage and load.

 

Constant current range:

For battery charging, we suggest that the input voltage of the module is less than the discharge cut-off voltage of the battery, and the output is equal to the charging cut-off voltage of the battery. Otherwise, we cannot guarantee a constant current range. Using resistive loads to test the constant current range will be relatively narrow. The minimum current is equal to the input voltage divided by the load impedance, and the maximum current is equal to the output voltage divided by the load impedance. Therefore, the constant current value has a maximum and minimum value, which is not as large as you want or as small as you want

5. It is strictly prohibited to use short circuited loads to regulate current

6. Two or more modules cannot be used in parallel for both input and output, otherwise the current limiting function will fail

7. The voltage difference between input and output is not suitable, otherwise the constant current function cannot be guaranteed. For example, some friends use a 12V battery to boost to 14V to charge the 12V battery, which will burn the fuse if the current is too high.

8. The normal voltage of the module is normal, and some laptops cannot be charged and used. This is a non quality issue because current computers have recognition functions and may refuse to use power supplies from non original chargers

 

Solution to the problem of blue light on:

This problem occurs when the input voltage is below 24V

Solution:

1. Increase the input voltage above the undervoltage protection voltage to release it

2. Adjust the undervoltage protection threshold, and counterclockwise adjust the threshold value to decrease

3. Add a description about the setting of undervoltage protection

Input low battery protection adjustment: Low battery protection is mainly aimed at preventing the battery from being over discharged when the input power supply is a battery. If the battery voltage is too low, it can damage the power module and battery. For example, setting low battery protection for 12V batteries. Connect a voltage to the input terminal of the power module (for example, a 12V battery can be set to 10V for undervoltage protection), and use a screwdriver to adjust the undervoltage protection potentiometer (increase the clockwise protection voltage value and decrease the counterclockwise protection voltage) until the undervoltage light is on. At this time, the low battery protection voltage is 10V. When the battery voltage drops to 10V, the power module will not boost voltage (the input voltage is equal to the output voltage).
