Re: Transformers: was Power supply question

Ballendo,

I have found discarded UPSs an excellent source for transformers. I
have one that came out of a 1.5kW system, gives 33 VAC, the ouput is
3 parallel 14 gage solid copper leads, never been able to fully load
it, must be about 40+ amps.. I picked up another at the local re-
cyle yard, 14.4 VAC ouput rated for 750 watts, $3.00.
