I'v got a BR800-FR that will not switch to AC power. When I plug it in it does not start, but I can start it by holding the I/O switch for a couple of seconds. It then does a self-test and remains on battery power.

The powerchute software indicates that the UPS thinks incoming AC fluctuates between 150 and 400 VAC, whereas in reality it's a nice and clean 230 VAC. Output voltage is only 200 VAC.

So far I've replaced the (4) elco's with new ones and installed new batteries (26 VDC).

I'm not an electronics engineer so this is as far as my hocus pocus goes. Anyone got a clue which component(s) might be broken and need replacement?
