Let's start out by pinpointing the facility desires of our home server, since it is easily the most very simple of our setups. If you would like be particularly precise together with your calculations, You should use a power meter to evaluate the actual usage designs of one's gadgets.
This is largely the real-earth Model from the idealized waveform demonstrated in fixer1234's solution. The solution to my dilemma earlier mentioned, then, is "Yes, they seriously do make UPSes with output top quality that negative."
I labored with Lee Johnson—an electrical engineer with over fifteen decades of working experience developing and screening electronics—to ascertain the surge-safety abilities of each and every UPS.

If that's the case, would there be any method to detect it, and would the substitution boards also be at risk?

When I wouldn't stress excessive about what lousy power good quality would do to An electrical drill, you can find motor-pushed gadgets I would not want to operate from the lousy-good quality UPS, such as a CPAP device.
Very well… that is a tiny terrible, essentially.
