Tripp Lite VR550U Series 550VA 300W Line-Interactive UPS -8 NEMA 5-15R Outlets, AVR, 120V, 50/60 Hz, USB, Desktop/Wall Mount - Ultra-compact Desktop/Tower/Wall Mount-AVR - 8Hour Recharge -120 V AC

Desktop UPS provides battery backup support with automatic voltage regulation (AVR) for your home/office network system or home theater. 550VA/300W/120V Battery Backup for PCs, Home Theater or Digital SignageThe line-interactive AVR550U UPS system with AVR protection provides reliable battery backup and AC power protection against blackouts, brownouts, over voltages, surges and line noise that can damage valuable electronics or destroy data. The eight-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 32 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available. 8 NEMA 5-15R Outlets Protect Your Connected ComponentsFour 5-15R outlets provide battery backup, surge protection and voltage regulation for your computer, monitor and other crucial components.

The other four 5-15R outlets provide surge suppression only for printers, speakers and other desktop equipment regarded as non-essential during a blackout. A high >95% 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 over voltages. The AVR550U can correct brownouts as low as 89V and over voltages 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. Combats Electromagnetic Interference That Can Harm EquipmentVarious electromagnetic and radio sources found in virtually every home and business can cause disruptive interference on the AC line. Known as EMI (electromagnetic interference) and RFI (radio frequency interference), this line noise is a common cause of performance problems and can lead to incremental hardware damage, data corruption and audio/video transmission problems. The AVR550U incorporates technology that filters out disruptive line noise so that it won't affect your equipment.

Home-Friendly Alarm and Diagnostic LEDs Keep You Informed 24/7The UPS remains silent in both line and battery backup modes. The alarm sounds only to report low battery, battery replace, overload and fault condition. Dual front-panel LEDs report line and battery mode operation. HID-Compliant USB Port Allows for Automatic Saves and ShutdownsThis USB port connects the AVR550U to a computer running free downloadable Power Alert software to enable safe unattended file saves and system shutdown in case of a prolonged power failure. USB cable is included. Compact Housing Compatible with Easy Desktop or Wall-Mount InstallationThe space-saving ABS housing fits on a desktop, shelf or anywhere else convenient to your workstation or home theater.

Keyhole mounting tabs on the rear allow easy wall-mount installation. The five-foot power cord with NEMA 5-15P plug connects to any compatible AC outlet
