The Tripp Lite INTERNET350U is a 350VA/210W standby UPS battery backup system designed to protect home office, media center, and small business equipment from blackouts, brownouts, overvoltages, surges, and line noise. It operates on 120V AC with a NEMA 5-15P input plug and a 5-foot power cord.

The unit features six NEMA 5-15R outlets — three providing full battery backup and surge protection for critical equipment, and three providing surge suppression only for peripherals. Wide outlet spacing accommodates bulky transformer plugs. The UPS delivers 316 joules of surge suppression and dual RJ11 network data line protection jacks for modem or telephone connections. A HID-compliant USB port connects to a computer running Tripp Lite's free PowerAlert software for automatic file saves and safe system shutdowns during prolonged outages. At half load (105W), the INTERNET350U provides approximately 7 minutes of runtime, and roughly 2 minutes at full load (210W). The internal VRLA battery recharges to 90% in about 6.5 hours and is user-replaceable via an access door.

The home-friendly design remains silent during normal and battery backup operation, sounding an alarm only for low battery or fault conditions. A front-panel LED indicates operating status. The compact ABS housing supports desktop placement or wall-mount installation via rear keyhole tabs. High line-mode efficiency (>98%) reduces energy consumption and heat output. The unit is ENERGY STAR certified and RoHS compliant, and comes backed by a 3-year limited warranty and Tripp Lite's $100,000 Ultimate Lifetime Insurance. Package includes the UPS unit, USB cable, and owner's manual.
