The line-interactive AVR900U 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 12-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 47 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available.

Six 5-15R outlets provide battery backup, surge protection and voltage regulation for your computer, monitor and other crucial components. The other six 5-15R outlets provide surge suppression only for printers, speakers and other desktop equipment regarded as non-essential during a blackout. A high >96% 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 AVR900U 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 AVR900U 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 AVR900U 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 by from Works great.....but....needs software upgrade I use this to back up my computer and two monitors. Works as described. The software that you can download to control the unit is archaic. Needs a complete upgrade and for that matter does not even recognize the unit. I would give it 5 stars if the software worked. Other than that.....great backup and AVR.

Rated 5 out of 5 by from Excellent performance I have used two of these for a number of years. They have reliably provided backup power during somewhat frequent short term power outages. I believe these two units saved our computers and related equipment when we received a close lightning strike and the power surge was instantly controlled to our equipment. This is an excellent product.

Rated 5 out of 5 by from So far so good! Very easy setup, not much more than a surge protector. Gives you ample time to power down devices, or a bridge for a whole house generator to kick on and take over.

Rated 5 out of 5 by from I would recommend this for everyone who owns a TiVo/DVR My TiVo, the company that invented the DVR used to reboot at times. The cause being windy days with power blips. Used to spilt my recordings. Now with the TrippLite battery backup this is no longer issue.

Rated 5 out of 5 by from From what I can tell this is truly a good choice I use this UPS for a PC, Smart TV, Speakers, and clock. I had to turn off the breaker for an extended time but did shutdown the PC since it draws the most and the time needed was above the limits of the UPS, but the other items remained online while the breaker was off. This unit replaced another brand that would drop everything in a split second and it was only a couple years old. So far, so good.

Rated 5 out of 5 by from Nice Unit...Very Clear Instructions for a Change. When you read the reviews it's apparent this company cares about its customers and honors its warranties.

Rated 5 out of 5 by from Simple & Effective! This UPS has worked great right out of the box. Easy to set up and get going. I love how simple it is, but very effective. After have 2 different company UPS before, and both of them needing replacement, I decided to try something different! I'm so glad I did. Very happy with the purchase!
