try checking the ‘FUSE’. in electric troubleshooting, usually a ‘dead circuit’ is due to a busted fuse caused by the power surge. there is a fuse socket in the UPS casing (or voltage regulator), try to locate it and replace. it is a must to have a replacement fuse(s) handy for instances like this.
CAUTION: before trying to locate/replace the fuse, make sure that the UPS or voltage regulator is unplugged to avoid electrical shock.

I agree with all the previous inputs. So all I have to contribute is that the capacity of UPS may simply not be enough for a really large CPU, a IBM server perhaps.

Mico,
Could be a dead battery. UPS battery life runs between 1 to 2 years depending on type of UPS.

I also have some problems with my UPS. It doesnt work anymore…it doesnt turn on when its plugged. Whats up with that? Sorry Gerry samantalahin ko na chance na may tumolong din sa kin :D

Thanks guys! Getting rid of the AVR now.

Bad battery, if it happens all the time. But sometimes, there is a rare kind of power fluctuation that UPS can’t handle.

Also, don’t use the AVR anymore, it’s not good for the UPS. The UPS has it’s own AVR built in.

you could try upping the sensitivity on the UPS (if it has variable sensitivity)…

Hi Gerry,

Ran into a similar problem a few years back when I was still with UPLB, and didn’t understand the technical explanation back THEN, either. I knew I should have paid attention in High School electrical shop class.

But anyway, I was told by our tech people not to connect that particular UPS to that particular AVR… something about the capacity of the AVR. I remember asking if it was possible to get an AVR that had a higher capacity (I suspect he was talking Amperage), but all I got was a quizzical look because he seemed to know I wouldn’t be able to understand the explanation anyway. He asked me why I wanted to connect the two together, and his solution was… to give me an extension cord so I could plug the UPS onto naked power, as you call it.

“You’ll be fine,” he assured me. But then of course I was just handling conference presentations at the time. I wasn’t exactly doing art.

But perhaps you should casually ask an electrician about the amperage and voltage capacities of your AVR and UPS?
