A mini-tower UPS with line interactive topology, the CyberPower Intelligent LCD Series BRG1500AVRLCD provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The BRG1500AVRLCD 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. Two USB charge ports (2.1 Amp shared) rapidly power portable devices such as mobile phones, MP3 players, and cameras. The BRG1500AVRLCD comes with a five-year warranty (including coverage of batteries) and a $500,000 Connected Equipment Guarantee.
