The CyberPower Systems CP900AVR UPS offers advanced power protection in a sleek and rugged tower. Automatic Voltage Regulation (AVR) ensures that all your electronics are receiving clean and stable AC power. Designed for mid-level to upper-level computer systems, the CP900AVR guards against surges/spikes, and also offers battery backup in the event of brownouts or total power loss. If your PC is unattended, PowerPanel PE Power Management software will automatically save and close open files and also shutdown the computer system in an intelligent and orderly manner. The CP900AVR also has full dataline protection: RJ11/RJ45 (phone, fax, Ethernet, network, DSL) and RG-6 coax (DSS, cable modem, satellite, cable TV). The convenient tower designs allows for placement on the floor, inside a workstation cabinet, or directly on the desktop. "Surge-Only" outlets are perfect for the addition of peripherals such as monitors, printers, scanners, iPods, or CD/DVD players.
