A mini-tower Ups with line interactive topology, the CyberPower Intelligent Lcd CP1350AVRLCD3 provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The CP1350AVRLCD3 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.Battery BackupSupplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown.Surge ProtectionDiverts excess voltage away from sensitive electronic equipment during an Ac power surge or power spike to prevent damage.Automatic Voltage Regulation (AVR)AVR increases the Ac power and maintains a safe voltage level without switching to battery mode and conserving battery life.
