Compact Desktop Power Protection

The Tripp Lite AVR550U is a 550VA 300W line-interactive UPS designed for desktop computers, home theatre gear and small office equipment. It delivers 120V output with automatic voltage regulation that corrects brownouts as low as 83 volts without using battery power. Eight NEMA 5-15R outlets provide battery backup and surge protection for multiple devices. A USB port enables communication with power management software.

Ideal for Basic Backup Needs

This unit suits users who need a few minutes of runtime to save work and shut down safely during outages. Typical backup lasts 32 minutes for an efficient desktop with a small LCD monitor at half load, dropping to 9 minutes at half load and 2 minutes at full load. Buyers who require extended runtime for servers, networking racks or high-power workstations should consider larger capacity units. The 400 joule surge rating covers basic transient protection but not whole-house events.

Simple Setup With Replaceable Battery

Desktop, tower or wall mounting options fit tight spaces and the 11.80 lb weight keeps it stable. Connect equipment to the eight outlets, plug the USB cable into a PC and install the management software for automatic shutdown. The valve-regulated lead-acid battery recharges to 90 percent in 2 to 4 hours and is user-replaceable when capacity fades after several years. Common issues include forgetting to enable the USB monitoring or exceeding the 300 watt load limit.

Domande su questo articolo

Does the AVR550U need any extra equipment to start protecting my PC?

No. It ships with a built-in 12 V valve-regulated lead-acid battery and a standard NEMA 5-15P input cord, so you just plug it into a 120 V wall outlet and connect your computer.

Can I keep my older router and printer on the same unit?

Yes. The eight NEMA 5-15R outlets accept standard North-American plugs, and the 300 W / 550 VA rating covers typical legacy routers, printers and similar low-draw devices alongside a modern PC.

How do I confirm the AVR550U is regulating voltage correctly after setup?

Connect the USB cable to your PC and install Tripp Lite's free monitoring software; it reports real-time input voltage, output voltage and AVR status so you can verify the unit is boosting brownouts down to 83 V and trimming over-voltages.
