Trying to figure out the easiest way to come up with a cheap 80 volt ~8 amp DC power supply for the LED flash project I posted in the projects section. At my disposal are several UPS power supplies and a 1000 watt 220-110 step down transformer. The supply doesn't really need to be regulated.
If I reverse the step down transformer I will end up with about 55 volts RMS, full wave bridge and a couple caps will get me close to 8o volts but not quite. ~77 volts with no load.
Wondering if I could cannibalize a UPS power supply and come up with anything usable. The UPS supplies are mostly APC and Direct UPS with batteries that died and weren't worth replacing. Imagining schematic might be hard to come by and the transformers probably have a low voltage secondary for the inverter.
Only other thought is a switching supply from scratch with the hard part again coming up with the proper transformer.
Any other ideas for something that won't cost several hundred bucks?
Thanks
