AVR UPS systems from CyberPower use line interactive topology for guaranteed power protection for desktop computers, workstations, personal electronics, and home networking/VoIP. They provide simulated sine wave battery backup power during outages, maintain steady voltage during brownouts, and offer surge protection against overvoltages and power spikes. Features include Automatic Voltage Regulation (AVR), energy-saving GreenPower UPS design, and data line protection. The included monitoring software allows for easily viewable power statuses and safe shutdown of the UPS.
