The CyberPower CP800AVR uninterruptible power supply (UPS) system provides battery backup and surge protection for lightning-induced surges and other power events that can damage electronic equipment. This UPS, with line-interactive topology, uses simulated sine wave output to deliver battery backup to power connected electronics during a utility power failure. The unit has enough runtime to perform a graceful shutdown to protect against the loss of data and damage to valuable desktop computers, workstations, networking devices, and home entertainment systems.
