On the smaller panels, you do not need as large a power supply as on the bigger panels. This transformer looks like a large black 2 pin unit you would find on your cassette recorder, or you Cell phone recharger system. Has 3 screw terminals on the back, out of sight. Good, clean transformer. Connect wires to the outside pins, the one in the middle is there to confuse you, just ignore it, I doPricing:
