A mini-tower UPS with line interactive topology, the CyberPower Intelligent LCD CP1500AVRLCDTAA provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and VoIP phone systems. The CP1500AVRLCDTAA 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. The CP1500AVRLCDTAA comes with a three-year warranty (including coverage of batteries), a $500,000 Connected Equipment Guarantee, and complies with the U.S. Trade Agreement Act (TAA).
