Is PFC Sinewave important - What I found
I'm in the market for a new UPS (Uninterruptible Power Supply) for my home/office setup and trying to decide if "PFC Sinewave" (from CyberPower - Amazon link) is a marketing gimmic or valuable.
This CyberPower news article says:
higher end workstations and computer systems that incorporate Active Power Factor Correction (PFC) power supplies may unexpectedly shut down or crash entirely when used with a simulated sine wave UPS.
CyberPower use the term, PFC Sinewave, and APC (APC 1500VA/900W UPS ) uses the term Sinewave UPS. When searching for PFC Sinewave the results were all related to CyberPower which makes me believe this is a marketing term; which is why I'm asking the question.
Searching for an answer - PFC Sinewave vs Sinewave
I currently have an APC 1000VA/600W that shuts down within 15 seconds of a power outage. When researching a more powerful unit, I noticed that my unit is a Stepped Sinewave UPS and from my reading it appears that I want a Pure Sinewave UPS.
This article (from blog.tripplite.com) explains the difference between the two.
a pure sine wave UPS system and a simulated sine wave UPS system is that a pure sine wave system in battery backup mode is guaranteed to produce a cleaner output for any piece of equipment connected to it.
A SO link I found provided a detailed discussion about what true sinewave UPS but didn't answer my question
a non-sine waveform can cause a shutdown, defeating the whole purpose for having a UPS
So back to my original question Is PFC Sinewave important? Is it the same as a sinewave UPS?
The answer will help me pick the next UPS I get (looking for a UPS that provides a pure sinewave).
