Enercon 1kw Universal Compak Power Supply Model# 1M3353-08 Volts: Input 115 - Output 90 Amps: Input 12 - Output 15 Freq: Input 50/60 - Output 10-30 khz Phase: 1 From the exterior this unit looks used. The interior of this power supply is pristine. It looks new on the inside. I have not tested the unit, I've only done a visual inspection. Upon inspecting the interior I noticed that there is a capacitor at the corner of the main board that it loose. The thick cable that is next to it hits it when the door is opened or closed and this loosened the cap. I photographed this in the last two pictures. You will want to have that checked before use. At this price you could part this out and come out ahead.
