Know your gear

The standby INTERNET900U UPS system 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, NAS drives, HDTVs, Blu-ray players, game consoles, media players, DVRs and audio receivers.

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 INTERNET900U should keep an energy-efficient desktop computer with small LCD monitor powered as long as 41 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 and surge protection 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.

By meeting strict EPA efficiency guidelines, this ENERGY STAR-certified UPS system helps you save money and energy. A high >98% line mode efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.

A 316-joule surge suppression rating protects connected components from the harmful effects of power surges. Dual network data line surge suppression jacks protect a wired peripheral from dangerous surges on a single 10/100Base-T or dial-up network connection.

This USB port connects the INTERNET900U 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.

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 INTERNET900U 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 warn you of a low battery or fault condition. Front-panel LEDs indicate operating mode, low- and replace-battery, overload and fault conditions.

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 Easy installation and so far so good I just purchased and installed this product. The installation was as easy as it gets. I feel more at ease knowing that my PC is now plugged into a UPS. The only reason for 4 stars instead of 5 stars is that I do not know how this will perform in an actual power outage. If that happens, and this product performs as I expect it will, I will gladly revisit this review.

Rated 5 out of 5 by from I refer Tripp Lite to my friends often since buying the UPS. Northern California resident dealing with lots of power outs from the power company PG&E. Often on a generator. Got it to protect my equipment incase of an outage and have a single connection to the generator. It cleanly powers my audio system, led tv, led lights, and a couple other devices. No high pitched whining from the unit like some surge protectors do. Not crazy heavy or cumbersome. 10/10 product.

Rated 5 out of 5 by from Fatal flaw for home use The other reviewers here are all companies, but there's one fatal flaw for this unit for home use. It works fine for its main function, but there's one thing it does that it shouldn't... Beep... Forever... Unceasingly. There's no way to turn it off. I even tried to use the digital interface to modify the settings, but couldn't get it to go away. So if you have it any where near your bedroom, or really anywhere within earshot, it will wake you up or drive you crazy. With a mute button, this would be a great unit, without it, it's maddening.

Due to the number of devices, I need both a surge protector and a battery backup with the space to handle everything. NOTHING else on the market offers that.

Rated 5 out of 5 by from Tripp-Lite - the best and safest component to have! This Tripp-Lite component is just one of many that I use on a daily basis here in my Recording Studio, my live rehearsal venues, and in my personal computer setups. Tripp-Lite components are key to saving your studio projects or anything on your computers in all environments. There have been instances of unannounced power outages as well as the voltage spikes from many sources, some even naturally caused. I highly, highly recommend to anyone to have a few of these Tripp-Lite components installed and in use daily. Definitely a project saver!
