The CyberPower Smart App Sinewave PR1000LCDTAA is a mini-tower UPS with line interactive topology. It complies with the U.S. Trade Agreement Act (TAA). This model provides battery backup, power protection (using sine wave output), and surge protection for corporate servers, department servers, storage appliances, network devices, and telecom installations requiring Active PFC power source compatibility. The PR1000LCDTAA 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.
