Automatic voltage regulation (AVR): Also known as line-interactive topology, this is the extra Innovative form of electricity administration that takes advantage of a small transformer to be a buffer to compensate for electricity dips and surges without the need of relying on the battery.
Surge security: Making use of the exact same equipment and protocol we use to check surge protectors, we zapped Just about every UPS with 5,000-volt energy surges, measuring the number of volts they Allow via.
CyberPower’s CP900AVR has a simple-to-use interface with just two buttons (ability on/off and mute) and four indicator lights (showing once the device is turned on, once the battery backup kicks in, when AVR is activated, and when there’s a power overload) around the front of your device.
