Computerized voltage regulation (AVR): Also referred to as line-interactive topology, this is the much more Sophisticated type of electricity administration that utilizes a small transformer for a buffer to compensate for power dips and surges with no counting on the battery.
Surge protection: Implementing precisely the same devices and protocol we use to check surge protectors, we zapped Every single UPS with five,000-volt electric power surges, measuring the number of volts they Permit through.
