Know your gear
The line-interactive AVR550U UPS system with AVR protection provides reliable battery backup and AC power protection against blackouts, brownouts, overvoltages, surges and line noise that can damage valuable electronics or destroy data. The eight-outlet 120V battery backup is ideal protection for your home office, media center or commerce components, including computers, routers, printers, HDTVs, Blu-ray players, game consoles, ATMs, security systems and digital signage equipment.
Backup support allows you to work through short power failures and gives you enough time to safely save files and shut down your system in case of a prolonged blackout. Backup time varies according to load, but the line-interactive UPS system should keep an energy-efficient desktop computer with small LCD monitor powered as long as 32 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available.
Four 5-15R outlets provide battery backup, surge protection and voltage regulation for your computer, monitor and other crucial components. The other four 5-15R outlets provide surge suppression only for printers, speakers and other desktop equipment regarded as non-essential during a blackout. A high >95% line mode efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.
AVR protects your equipment from incremental hardware damage, data loss and performance problems caused by brownouts and overvoltages. The AVR550U can correct brownouts as low as 89V and overvoltages as high as 145V back to nominal 120V power continuously, all while keeping the battery fully charged and ready to take over in case of power failure.
A 316-joule surge suppression rating protects connected components from the harmful effects of power surges.
Various electromagnetic and radio sources found in virtually every home and business can cause disruptive interference on the AC line. Known as EMI (electromagnetic interference) and RFI (radio frequency interference), this line noise is a common cause of performance problems and can lead to incremental hardware damage, data corruption and audio/video transmission problems. The AVR550U incorporates technology that filters out disruptive line noise so that it won't affect your equipment.
The UPS remains silent in both line and battery backup modes. The alarm sounds only to report low battery, battery replace, overload and fault condition. Dual front-panel LEDs report line and battery mode operation.
This USB port connects the AVR550U to a computer running Tripp Lite's free downloadable PowerAlert software to enable safe unattended file saves and system shutdown in case of a prolonged power failure. USB cable is included. Battery independent restart ensures automatic UPS power-up without user interaction after lengthy power outages, even when batteries are expired and require replacement.
The space-saving ABS housing fits on a desktop, shelf or anywhere else convenient to your workstation or home theater. Keyhole mounting tabs on the rear allow easy wall-mount installation. The five-foot power cord with NEMA 5-15P plug connects to any compatible AC outlet.

Rated 5 out of 5 byelmariocarlos from Excellent Choice!I purchased my first device, and work ok but then had a problem. Looking for warranty I found a nearby store that took it in with few questions asked and replaced my unit in 1 week. The new device is working even better, and I can say this is a quality purchase if you are looking to protect core devices (without going the energy usage). Great product, great choice, totally recommended!

Rated 5 out of 5 byAdele240 from Good product for a reasonable price.Have purchased several AVR550U for individual work stations in a small office setting and they have worked well during the many power outages. They enable the user to save working documents and then shut down until power is restored.

Rated 5 out of 5 bywakoch from The 550U saved my system on 2-occasionsI've used Tripplite products for several years. (surge protectors, Isobars, USB hub, and 550U UPS#. On 2 occasions I experienced massive power failure's at my former home . The first rendered the UPS unusable #which Tripplite replaced# and the second stopped the surge. In both cases my computer and attachments were left undamaged. Another time I required new software for the UPS and the technician worked with me until we got it to work #well past his quitting time). I can't say enough about Tripplite.

Rated 5 out of 5 byruler1iam from EXCELLENT FOR PRICEI use this UPS for my Router and Cable modem. I live in Florida and we experience power hits that are quick. I prefer to keep my devices safe by using a UPS. This prevents me from burning up a router.
