8 of these. Despite the fact that that’s about 2 times as numerous volts as our favorite surge protectors let by means of, it’s however greater surge security than we’ve seen from every other UPS.
This UPS lacks high quality functions, however it has an abundance of retailers and provides enough electric power to keep a home Wi-Fi community up and working for so long as an hour and also a fifty percent when the ability goes out.
It offers ample surge security. In our tests, the CP900AVR knocked down our 5,000-volt surges to simply 540.four volts. That result isn’t pretty as good as what we noticed from our favorite surge protectors—none of which let through much more than three hundred volts in screening with identical devices and parameters—nonetheless it’s on the par with how our other UPS picks performed, and it implies that this UPS can shield your products in opposition to most home electrical power spikes, sags, and surges.
