Line Conditioners AND UPS Back-ups

[Anonymous user]

My company has a UPS Back-up attached to almost every PC in the office. Over the last 6 months plus, we've been having problems with our power stream from the electrical company. We've experienced many brownouts, but recently we've been seeing power spikes... from 127V-135V, and the spike have been lasting for minutes up to a couple hours. We are concerned about some of our devices (PC, Servers, UPS's...etc) burning up from frequent and long exposure to these power spikes and are looking into getting a couple line conditioners to regulate. My question is...Can you put a line conditioner on a PC or Server with a UPS attached (APC Back-up 550 or 650's)? If so, where would you put it... before the UPS or after?

i'd put it before that way it will reduce the amount of times a UPS would potentially go to battery or boost/trim when it sees an issue with the input power. and when the Back UPS is online anyway, it pretty much passes the power through if it does not have boost or trim function (depending on model).
