Surge defense: Implementing a similar equipment and protocol we use to check surge protectors, we zapped Every single UPS with 5,000-volt electrical power surges, measuring what number of volts they Permit by way of.
Its most output is within the decrease aspect—we measured nearly 470 W in our screening—but that ought to be a lot of power for that six battery-backed shops to aid Fundamental principles including home Wi-Fi equipment.

You will find automatic voltage regulation to fix minimal energy fluctuations during the day with out involving the battery. On the other hand, the CP800AVR utilizes simulated sine waves as an alternative to pure sine waves, so don't plug high-priced A/V machines into it If you'd like All those to perform at their very best.
