installing new UPS for my office and needs electrical work...

Why waste money on a device that does not claim to do effective protection?

Output from this 120 volt UPS in battery backup mode is 200 volt square waves with a spike of up to 270 volts between those square waves. Power so 'dirty' as to potentially harm power strip protectors and small electric motors. And ideal power for all electronics. Because electronics have long been required to be so robust.

What are you trying to accomplish? All electronics contain superior surge protection - as the 'dirty' UPS electricity demonstrates. Anything that might work on an appliance's power cord is already inside. Protection so robust as to make that 'dirtiest' UPS power into ideal clean electricity.

Your concern is a transient so major as to overwhelm existing protection. Only an earthed protector - where power enters the building - can divert such energy harmlessly into earth.

I was having weird issues and wondered if I had brown power issues. Without an O-scope or even a good and fast true RMS meter I couldnt tell, so I just said hell with it and bougt a Cyberpower CP1350AVRLCD. The question stemmed from me being too lazy when I got my UPS. I simply pulled the plug for the power strip and plugged it into the back of my UPS.

The Cyberpower was "reviewed" (takes salt grain) to be one of the LESS crappy simulated sine wave ones (stepping sine wave). I never really considered the output effects on my power strip until after reading your guys thread here. Thus the question.

With my knowledge of MOV's and how they work, and what you say about the output of a UPS on battery(again i personally have never scopped one out), I could easily surmize that prolonged crappey battery output from the UPS could cause the MOV's in the surge strip to overheat, fail, and/or cause a fire. That is assuming that the peaks are suffecient, prolonged, and frequent enough. I guess I should just go ahead and pull out the strip until I can scope out the battery output of my UPS and see what the ACTUAL output looks like.

On a side note I really need to invest in a good meter that reads TRUE RMS.
