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 INTERNET350SER UPS System. It provides reliable battery backup that can keep a basic desktop PC operational for up to 12 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.

Ideal for Protection of Home or Office PCs and Peripherals
With reliable battery backup, tel/DSL jacks and a DB9 serial communication port, the INTERNET350SER offers a complete power protection solution for a wide range of home and office electronics. The INTERNET350SER features a split-outlet design with 6 total AC outlets: 3 to provide battery backup support and surge protection for computers, monitors and other critical components; 3 to provide surge protection only for peripherals such as printers and scanners that do not need battery backup. Its small footprint allows the INTERNET350SER 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 INTERNET350SER features an internal battery that provides 2.5 min. of battery support for a full load (180 watts), 10 min. for a half-load (90 watts) or 12 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 if needed. Note: For applications requiring longer runtimes or a higher wattage a capacity, choose Tripp Lite's INTERNET550SER.

Protect Electronics Against Damaging Surges and EMI/RFI Line Noise
A sudden power surge or spike can damage or destroy electronic components and wipe out irreplaceable data. The INTERNET350SER features built-in surge suppression to protect all connected components and the data they contain. Various electromagnetic and radio sources can also 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 INTERNET350SER incorporates technology that filters out disruptive line noise, preventing it from affecting your equipment. In addition to AC outlets, the INTERNET350SER includes one set of tel/DSL (RJ11) jacks to protect a standard telephone, fax, dialup modem or DSL connection.
