Is the CyberPower CP1500PFCLCD a pure sine wave UPS?

[kenwaldmann]

I've been advised that the Antec TP-650C PSU that I installed in my PC would benefit from a pure sine wave UPS to avoid the PSU tripping off. CyberPower's website says that the CP1500PFCLCD is a pure sine wave UPS; however, a Tom's Hardware review from November 2010 says that it has "a modified triangular wave that CyberPower calls “Adaptive Sinewave” to eliminate the zero power state." Which is correct? Thank you.

I received the following answer from Pietro Boggio, Senior Technical Support Specialist at CyberPower:

"No digitally created wave can be a true mathematically curved analog wave. But the number of digital steps used to create the wave can be great enough that the electronics used in even the highest efficiency computer power supplies are unable to distinguish them from an analog wave. The total harmonic distortion of the output on battery is under 2% which means the output of the UPS is closer to a mathematically ideal analog wave than the power coming out most peoples walls.

"These units were created specifically for the needs of computer users with Active PFC power supplies. We put PFC in the model name to highlight the fact that these units are compatible with Active PFC Power Supplies."

I believe this adequately answers my question.

Kenwaldmann, I tracked this thread because it was one of the best questions I have seen on the forum; and I had no answer. Thank you for posting the answer from Cyberpower. That is really good and important information, and will come in handy in the future.
Welcome to Tom's and glad to have you with us.
