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 SMART550USB UPS System. It provides reliable battery backup that can keep a basic desktop PC operational for up to 30 minutes during blackouts. The SMART550USB features automatic voltage regulation to correct brownouts, assuring that connected equipment receives safe, regulated 120V nominal output, plus surge suppression and EMI/RFI line noise filtering to prevent hardware damage and performance problems such as poor-quality audio and video output. Free PowerAlert UPS software (available via Web download) enables safe unattended file saves and an orderly system shutdown in the event of a prolonged power failure.

Ideal for Protection of Home or Office PCs and Peripherals
With reliable battery backup, tel/DSL jacks and an HID-compliant USB port, the SMART550USB offers a complete power protection solution for a wide range of home and office electronics. The SMART550USB features a compact footprint, split-outlet tower design with six total AC outlets: three to provide battery backup support and surge protection for computers, monitors and other critical components; three to provide surge protection only for peripherals such as printers and scanners that do not require battery backup. Its compact, tower footprint allows the SMART550USB to be used in applications where space is limited.

Reliable Battery Backup
View larger

Reliable Battery Backup
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 SMART550USB features an internal battery that provides 4 min. of battery support for a full load (300 watts), 15 min. for a half-load (150 watts) or 30 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.

Automatic Voltage Regulation (AVR)
AVR protects connected equipment from incremental hardware damage, data loss and performance problems that can be caused by low-voltage conditions, commonly known as brownouts. The SMART550USB corrects brownouts as low as 89V to a nominal 120V, providing safe, computer-grade power to all connected components, without consuming battery power needed to support equipment through blackouts.

Protect Electronics Against Damaging Surges and EMI/RFI Line Noise

Protect Electronics Against Damaging Surges and EMI/RFI Line Noise
A sudden power surge or spike on a phone or network line can damage or destroy electronic components and wipe out irreplaceable data. The SMART550USB features one set of tel/DSL (RJ11) jacks that provide surge protection for a standard phone connection (cable included). Its 480-joule surge suppression rating protects connected components and data from the harmful effects of power surges. Various electromagnetic and radio sources can also cause disruptive interference on the AC and data lines. This line noise is a common cause of incremental hardware damage, data corruption and audio/video performance problems. The SMART550USB incorporates technology that filters out disruptive line noise, preventing it from affecting your equipment.

USB Port and Free PowerAlert Software
The SMART550USB 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.
