This is essentially the true-entire world version of the idealized waveform shown in fixer1234's solution. The answer to my issue previously mentioned, then, is "Of course, they seriously do make UPSes with output excellent that negative."
I labored with เครื่องสํารองไฟ 800va Lee Johnson—an electrical engineer with a lot more than 15 decades of practical experience coming up with and screening electronics—to determine the surge-defense capabilities of each and every UPS.
An influence failure is over an inconvenience—it could knock out essential equipment for hours on close. When you've got significant electronics that have to keep functioning when the power's out, You'll have an uninterruptible electrical power supply (UPS).
