Product Description

Power problems—including blackouts, brownouts, power surges and line noise—threaten your investment! They can damage or destroy PCs and other expensive equipment, wipe out valuable data and files, and degrade component performance. Get protected against these all-too-common power threats with Tripp Lite's AVR550U desktop UPS system. It provides reliable battery backup that can keep a basic desktop PC operational for up to 17 minutes during blackouts. Automatic voltage regulation (AVR) corrects low-voltage conditions (brownouts) back to safe 120V power without draining the UPS battery. Surge suppression and EMI/RFI line noise filtering prevent hardware damage and performance problems such as poor-quality audio and video output.

The AVR550U's 550VA/300-watt power rating provides ample capacity for a wide range of home and office PC setups, workstations, point-of-sale systems and more. It features 4 battery-supported AC outlets for computer, monitor and other vital system peripherals, plus 4 surge suppression-only outlets for accessories not requiring battery support. One set of tel/DSL (RJ11) jacks protects connected equipment on a tel/DSL line. One USB communication port plus free PowerAlert software (available from Tripp Lite via Web download) enables unattended system shutdown and file saves in case of a prolonged power failure. The AVR550U comes with $100,000 Ultimate Lifetime Insurance coverage for connected equipment (USA/Canada only) and a 3-year product warranty.

Automatic Voltage Regulation (AVR)

Automatic Voltage Regulation (AVR)
AVR protects your equipment from incremental hardware damage, data loss and performance problems that can be caused by low-voltage conditions (brownouts) and overvoltages. The AVR550U automatically corrects brownouts as low as 83V and overvoltages as high as 147V back to 120V without drawing on battery backup power that may be needed to support your equipment during a blackout.

Keep Working During Power Failures
UPS battery backup support enables you to work through short power failures, and provides time to save files and perform an orderly system shutdown in case of a prolonged blackout. The AVR550U features an internal battery that provides 3 min. of battery support for a full load (300 watts), 9 min. for a half load (150 watts) or 17 min. for a basic desktop PC. During normal operation, incoming utility power keeps the UPS battery fully charged so that backup power will always be available when needed.

Protect Electronics Against Damaging Surges and EMI/RFI Line Noise
The AVR550U features built-in surge suppression to protect all connected components and the data they contain. Additionally, various electromagnetic and radio sources can cause disruptive interference on the AC line. The AVR550U incorporates technology that filters out disruptive line noise, preventing it from affecting your equipment. To protect all electronics, the AVR550U includes one set of tel/DSL (RJ11) jacks to protect a standard telephone, fax, dial-up modem or DSL connection.

USB Port and Free PowerAlert Software
The AVR550U features an HID-compliant USB port (USB cable included). Used with Tripp Lite's free PowerAlert software (available from Tripp Lite as a Web download), this USB port enables safe unattended system shutdown and file saves in the event of a prolonged power failure. The USB port also enables integration with built-in power management and auto shutdown features of Windows®, Linux® and Mac OS® X.
