What parts to salvage/sell from a UPS?
why not sell the 3 phase one as an alternative to a rotary or static
inverter - no batteries needed. "Ignoramus18142" wrote in message ... I have three UPSes: 1. Clary OnGuard 3 phase 5 kVa UPS, no batteries 2. Clary OnGuard 1 phase 5 kVa UPS, no batteries 3. Ferrups 3.0 kVa inline model UPS (no outlets), no batteries All are working. I would like to demolish these UPSes, take out what I can sell and auction these parts on ebay. I recently demolished an even bigger Data General UPS (about 8 kW) and sold the capacitors from it for $75. The rest is a big pile of unidentifiable parts. Some look like huge diodes and transistors. I am afraid that some of those parts have value that I would have hard times capturing (maybe I took apart a large and usable rectifier, for example), so, I do not want to make the same mistake again. I would like to know which parts of those UPSes are really desirable. Capacitors? Rectifiers? Anything else? Any thoughts on this will be appreciated. I will use this as an opportunity to learn about electronics. Thanks! i |

Can they be used to provide the correct voltage to a high voltage motor that is cheap ? Convert farm like 2 phase into 3 phase on the output ? Understand what is possible before scrapping. The transformers might be most useful in the prior concepts. The inverter might be to custom.
