UPS problem

If it's plugged into known good power when you turn it on, and it's otherwise setup correctly, then return it to the seller for an exchange.

When I moved to this area, we were getting regular brown outs and power cuts (not much better now...lousy power company) so I bought a UPS for the PC, it was always going on backup mode. Went and bought another with more power output, more indicators, turns out our incoming voltage was 140/280Vac. Told the power company, wouldn't believe me but came out like a shot. Turns out some of their gear was faulty.

Might be an idea to check your mains volts.

Were there any effects from the high voltage, such as shortened lamp life, unexpected equipment failure, etc?

Difficult to say really, this was about 2 weeks after I moved to this area. We use 99% CFL's for lighting, so no very bright popping filaments! I guess most of our electronics like TV's could regulate ok. I wouldn't have known there was a problem until the UPS's detected the overvoltage. The power guys said some piece of equipment had been replaced temporarily by known faulty gear but it got left in permanently. Nice.

Sounds like an "Intermittent" or "Floating Neutral Buss" !! Yukio YANO
