eight of them. Whilst that’s about twice as quite a few volts as our favorite surge protectors Permit by way of, it’s even now better surge security than we’ve observed from any other UPS.
Surge security: Implementing a similar tools and protocol we use to test surge protectors, we zapped Just about every UPS with 5,000-volt electrical power surges, measuring the amount of volts they Permit by way of.
Irrespective of whether you use the less specific or even more precise process, you'll need a wattage price. For our calculation illustrations, we're going to use 400w as our price.

It has a circuit-reset button, as well as a compact light to indicate a wiring difficulty While using the outlet your UPS is plugged into.
