Tripp Lite INTERNET550SER UPS System

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 with Tripp Lite's INTERNET550SER UPS System. It provides reliable battery backup that can keep a basic desktop PC operational for up to 17 minutes during blackouts. Surge suppression and EMI/RFI line noise filtering prevent hardware damage and performance problems such as poor-quality audio and video output. The INTERNET550SER's 550VA/300W capacity provides ample capacity for a wide range of home and office PC setups, workstations, point-of-sale systems and more. It features four battery-supported AC outlets for computer, monitor and other vital system peripherals, plus four 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 DB9 serial communication port plus free PowerAlert software (available via Web download) enables unattended system shutdown and file saves in case of a prolonged power failure. The INTERNET550SER comes with $100,000 Ultimate Lifetime Insurance coverage for connected equipment and a 3-year product warranty.

Ideal for Protection of Home or Office PCs and Peripherals

With reliable battery backup, tel/DSL jacks and a DB9 serial communication port, the INTERNET550SER offers a complete power protection solution for a wide range of home and office electronics. The INTERNET550SER features a split-outlet design with eight total AC outlets: four to provide battery backup support and surge protection for computers, monitors and other critical components; four to provide surge protection only for peripherals such as printers and scanners that do not need battery backup.

Green High-Efficiency Design

High-efficiency operation—greater than 95%—saves energy, lowering your electric bill and reducing your carbon footprint. High-efficiency models also consume fewer resources during manufacture and distribution than previous models.

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 INTERNET550SER features an internal battery that provides 17 min. of battery support for a basic desktop PC, 11.5 min. for a half load (150 Watts) and 3 min. for a full load (300 watts). During normal operation, incoming utility power keeps the UPS battery fully charged so that backup power will always be available when needed.

Surge Suppression

A sudden power surge or spike can damage or destroy electronic components and wipe out irreplaceable data. The INTERNET550SER features 420 joules of built-in surge suppression to protect all connected components and the data they contain.

EMI/RFI Line Noise Filtering

Various electromagnetic and radio sources can cause disruptive interference on the AC line. This line noise is a common cause of incremental hardware damage, data corruption and audio/video performance problems. The INTERNET550SER incorporates technology that filters out disruptive line noise, preventing it from affecting your equipment.

Data Line Protection

The INTERNET550SER includes one set of tel/DSL (RJ11) jacks to protect a standard telephone, fax, dialup modem or DSL connection.

DB9 Port and Free PowerAlert Software

The INTERNET550SER features a DB9 serial communication port (DB9 cable included). Used with Tripp Lite's free PowerAlert software (available from Tripp Lite as a Web download), this serial port enables safe unattended system shutdown and file saves in the event of a prolonged power failure.

Versatile Installation Options

The INTERNET550SER features a space-saving, ultra-compact housing that fits on a desktop, a shelf or almost anywhere. Its 6-foot power cord features a right-angle plug that allows furniture to be placed flush against the wall. The INTERNET550SER's housing is equipped with integrated keyhole mounting slots for secure wall-mount installation.

Environmentally Responsible

The INTERNET550SER is manufactured in compliance with strict RoHS guidelines to minimize the use of hazardous materials, and its internal battery is 100% recyclable.

Ultimate Peace of Mind

The INTERNET550SER comes with $100,000 Ultimate Lifetime Insurance coverage for connected equipment and a 3-year product warranty.
