I was wondrering? My power supply is to low to power my 12 engine combo set up I was wondering what I could to rectify this problem? I have a Pirmary 120/240VAC Secondary 12/24VDC @ .60Hz single phase 1.0 Kva transformer and a moter speed control that I was going to use but i'm affraid if i do there may be to many amps runing through it and in an accoruance there where a short it would cause a pitting affect on my wheels. Do you think this is possible? also is there a over current protection device fast enough to prevent it? Thanks any help would be greatly apprecieated.
