Because uninterrupted power supply is crucial for the smooth operation of your sensitive electronic equipment, the PR2200RT2U Smart App Sinewave Rack/Tower Ups is designed to provide a seamless power transition during power outages, voltage fluctuations, and surges. This advanced Ups system is part of CyberPower's Smart App Sinewave series, known for its sine wave output that eliminates power gaps, preventing unexpected shutdowns of your equipment.The PR2200RT2U model is equipped with an Automatic Voltage Regulation (AVR) feature and battery equalization technology, both of which contribute to a longer battery life. AVR corrects minor power fluctuations without switching to battery power, while the battery equalization technology ensures each battery in a multi-battery string is charged to a similar voltage, improving overall performance and extending battery life.This Ups system is designed with user convenience in mind.
