A mini-tower UPS with line interactive topology, the CyberPower Intelligent LCD provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The BRG1500AVRLD2 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 BRG1500AVRLD2 comes with a five year warranty (including coverage of batteries) and a $500,000 Connected Equipment Guarantee.
