[ARC5] Salvaged Transformer

[Robert Eleazer]

I salvaged a big transformer out of a unit that I guess was a Trip Let  UPS.  All the windings have low resistances, around a few ohms.  Anyone know how to tell which winding can be attached to 120 VAC to get something useful?

I could use a Variac to bring up the power at low voltages.

Thanks,

Wayne
