A dual symmetrical power supply, designed in the UK on a top quality dual layer PCB. Perfect for powering up an audio amplifier or active crossover filter etc. Dimensions: 90mm x 45mm. Fully assembled and tested. The performance is excellent. Low noise combined with high EMC performance Components: 4 x 2200uF 50V electrolytic capacitors. 2 x 100nF 50V ceramic capacitors. 4 x 10nF 50V capacitors. 4 x 1N5401 rectifier diodes. 2 x 3 way 5.08mm terminal blocks. 4 x Nylon mounting pillars. We recommend powering this board with an 80VA max toroidal transformer with a dual output voltage to suit your amplifier. Maximum input voltage 2 x 35V AC. For powering a crossover filter we recommend a 2 x 6V toroidal transformer. Because mains electricity is involved, we recommend this kit is installed by qualified DIYers only. Also for your safety, we recommend the PCB and transformer are installed in a secure enclosure. For your added safety, if you wish to use a metal enclosure an earthing point is available on the board.
