I'm trying to build a current source for testing solid state overcurrent relays. At my disposal I have 0-120 variable AC and/or DC. 480 constant ac and 120 constant AC.
I'm pulling my hair out researching ways to do this. At my old job, technicians would build these as test carts with some types of transformers, but I've yet to find anything for this except a typical voltage variac.
I'm trying to get at least 0-10 amps adjustable.
Any ideas?
