The line-interactive UPS is similar in operation to a standby UPS, but with the addition of a multi-tap variable-voltage autotransformer. This is a special type of transformer that can add or subtract powered coils of wire, thereby increasing or decreasing the magnetic field and the output voltage of the transformer.
This type of UPS is able to tolerate continuous undervoltage brownouts and overvoltage surges without consuming the limited reserve battery power. It instead compensates by automatically selecting different power taps on the autotransformer.

So in essence, what I necessarily want is a "line-interactive" standy UPS (square wave output) and I'm good to go? I'm skeptical in the square wave vs. pure sine wave output, I'm leaning towards pure sine wave (of course) but I'm not sure if it's even needed?

I'm pretty sure that if you have a power supply that has Active Factor Correction, you need one that does either an approximated/stepped sine wave or a pure sine wave, but not one that does a square waveform.

I thought approximated/stepped sine wave is the same as square wave.

APC is "more common" though, right?

I was reading a lot of information (really a lot smile.gif) today and I understand more about UPS now. The only thing that bothers me now is regarding using stepped sine wave/simulated sine wave with active PFC PSUs like my PSU.. I hear that it causes problems with active PFC PSUs. What can you guys comment about this?

Honestly, you seem to be going way too deep in on this...

BTW... what is your budget for a UPS? Are you "unlimited" with all of these specific questions? I'm sure that the ones we've already recommended to you would protect your PSU just fine...


Seriously, you are getting to the point where it seems that you aren't really serious... going around and around in circles here.

I'm really sorry. I think I'm in an information overload state right now that's why I tend to forget some things. Anyway, I reread the whole thread from the beginning and realized that you've already commented about PFC even with your first post here. Are you certain that a stepped approximation to a sinewave output waveform UPS can handle PFC PSUs well enough similar to a pure sine wave one?

And do you think that your UPS (CyberPower CP1500PFCLCD) is better in price than the APC BR1500G simply because the Cyperpower outputs a pure sinewave for our PFC PSU for the same price range to that of the APC which outputs a stepped approximation to a sine wave waveform?

If surge protection also wears out in a UPS through time, can it be replaced?

I may have to see the price ranges first before I could decide what budget I have.

Bump!

I just noticed that Cyberpower doesn't provide a good UPS with Input/Output of 230V which is the mains voltage of our country. APC does provide the BR1500GI but is not a pure sine wave output UPS. I read that non pure sine wave UPS are prone to make the PSU produce a buzzing sound, is that true?
