CyberPower Intelligent LCD CP1000AVRLCD is a mini-tower UPS with line interactive topology. This model provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The CP1000AVRLCD 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 LCD CP1000AVRLCD comes with a three-year warranty (including coverage of batteries) and a $350,000 Connected Equipment Guarantee.
