Tripp Lite UPS 900VA 480W Desktop Battery Back Up AVR Compact 120V USB RJ11 - Ultra-compact Desktop/Tower/Wall Mount - AVR - 8 Hour Recharge - 2.70 Minute Stand-by - 120 V AC Input - 110 V AC, 115 V AC, 120 V AC Output - 12 x NEMA 5-15R

900VA/480W/120V Battery Backup for PCs, Home Theater or Digital SignageThe line-interactive AVR900U UPS system with AVR protection provides reliable battery backup and AC power protection against blackouts, brownouts, overvoltages, surges and line noise that can damage valuable electronics or destroy data. The 12-outlet 120V battery backup is ideal protection for your home office, media center or commerce components, including computers, routers, printers, HDTVs, Blu-ray players, game consoles, ATMs, security systems and digital signage equipment.
Allows Time to Back Up Critical Files During a Blackout Backup support allows you to work through short power failures and gives you enough time to safely save files and shut down your system in case of a prolonged blackout. Backup time varies according to load, but the line-interactive UPS system should keep an energy-efficient desktop computer with small LCD monitor powered as long as 47 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available.
12 NEMA 5-15R Outlets Protect Your Connected ComponentsSix 5-15R outlets provide battery backup, surge protection and voltage regulation for your computer, monitor and other crucial components. The other six 5-15R outlets provide surge suppression only for printers, speakers and other desktop equipment regarded as non-essential during a blackout. A high >96% line mode efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.
Automatic Voltage Regulation (AVR) Corrects Low- and High-Voltage ConditionsAVR protects your equipment from incremental hardware damage, data loss and performance problems caused by brownouts and overvoltages. The AVR900U can correct brownouts as low as 89V and overvoltages as high as 145V back to nominal 120V power continuously, all while keeping the battery fully charged and ready to take over in case of power failure.

316 Joules Fight Back Against Unexpected Power SurgesA 316-joule surge suppression rating protects connected components from the harmful effects of power surges.
