CyberPower AVR Series CP685AVR UPS - 390W - 685 VA - 8 Ah

A compact UPS with line interactive topology, the CyberPower CP685AVR provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The CP685AVR uses Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, which extends battery life. AVR is essential in areas where power fluctuations occur frequently.
