8 of these. Though that’s about two times as many volts as our favorite surge protectors Allow through, it’s still greater surge security than we’ve found from some other UPS.

You can get a affliction such as this In case you are next to a professional or industrial facility with major machines cycling on and off.
It provides sufficient surge defense. Within our testing, the CP900AVR knocked down our five,000-volt surges to just 540.four volts.
