The PR3000RTXL2UN is a Smart App Sinewave rack/tower convertible UPS with line-interactive topology, surge protection, and battery backup. CyberPower's Smart App Sinewave series creates a sine wave output devoid of power gaps which could cause unexpected shutdowns of sensitive equipment. The Smart App Sinewave PR3000RTXL2UN improves battery life through battery equalization technology and Automatic Voltage Regulation (AVR), which corrects minor power fluctuations without switching to battery power. The enhanced chassis design with an easy-to-access toolless front panel, captive screws for battery panel access, and color-coded rear panel make battery changes and installations simple and fast. The PR3000RTXL2UN also has an innovative LCD panel that rotates 90°, tilts for a better viewing angle, and provides information on 47 different settings including UPS stats, UPS setup and control management, and testing options. This model accepts the BP48VP2U02 Extended Battery Module (EBM) for expanded runtime during power outages and includes pre-installed RMCARD205 network management card for remote management and control via a standard web browser or network management system.
