Tripp Lite 800VA 475W UPS Tower 120V Battery Back Up Desktop AVR LCD USB - UPS - 475 Watt - 800 VA

This UPS 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. This 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, digital signage equipment and other professional applications.

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 78 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available.

Six UPS supported outlets provide both battery backup, surge suppression and voltage regulation for your computer, monitor on other critical items. Two additional outlets provide surge suppression only for printers, speakers and other desktop items not requiring battery backup. A high 95% line mode efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.

AVR protects your equipment from incremental hardware damage, data loss and performance problems caused by brownouts and overvoltages. This UPS 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.

A 316-joule surge suppression rating protects connected components from the harmful effects of power surges. Combats Electromagnetic Interference That Can Harm Equipment

Various 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. This UPS incorporates technology that filters out disruptive line noise so that it won't affect your equipment.

The LCD touchscreen offers five screens of UPS and site power information when the UPS is operating in either on-line or battery power mode. It displays vital voltage, load and battery data, as well as critical fault status. An audible alarm will sound in case of low battery, excessive load and fault condition.

Use the included cable to connect your device to the UPS USB port. Desktop systems can use Tripp Lite's free downloadable PowerAlert software to enable safe unattended system shutdown in the event a power failure outlasts your UPS battery runtime... Even when you aren't around. Battery independent restart ensures automatic UPS power-up without user interaction after lengthy power outages, even when batteries are expired and require replacement.
