350VA/210W/120V Battery Backup for PCs, Home Theater and Digital Signage

The standby INTERNET350U 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 six-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.

Allows Time to Back Up Critical Files During a Blackout

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 INTERNET350U should keep an energy-efficient desktop computer with small LCD monitor powered as long as 13 minutes. During normal operation, incoming utility power keeps the replaceable internal battery fully charged, so backup power will always be available.

6 NEMA 5-15R Outlets Protect Your Connected Components

Three 5-15R outlets provide battery backup and surge protection for your computer, monitor and other crucial components. The other three 5-15R outlets provide surge suppression only for printers, speakers and other desktop equipment regarded as non-essential during a blackout. Each outlet offers wide spacing to accommodate bulky transformer plugs. A high >98% line mode efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.

316 Joules Fight Back Against Unexpected Power Surges

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.

HID-Compliant USB Port Allows for Automatic Saves and Shutdowns

This USB port connects the INTERNET350U to a computer running free downloadable PowerAlert software to enable safe unattended file saves and system shutdown in case of a prolonged power failure. USB cable is included.

Combats Electromagnetic Interference That Can Harm Equipment

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 INTERNET350U incorporates technology that filters out disruptive line noise so that it won't affect your equipment.

Home-Friendly Alarm and Diagnostic LEDs Keep You Informed 24/7

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. A front-panel green LED indicates operating mode and fault status.

Compact Housing Compatible with Easy Desktop or Wall-Mount Installation

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 Quality Product and Great Support Service Purchased the INTERNET350U UPS and had to wait 10 days for delivery, I guess they were back-ordered but it came as described. It looks and feels like it is made with quality. Bought the UPS for my router, that is 1.5 hour away, to ensure it stays on during a power bump. Usually, I need to reset my router, not anymore when connect to this UPS. The UPS stays on, even after a loss in power with the auto-start feature. I haven't tested if the UPS will auto start after the battery runs out. I was told it will auto-start after I called their support line and Jason answered my concerns, great service.

    Rated 5 out of 5 by from Compact and reliable We use this for a very compact mobile recording rig. We don't need a lot of wattage, but we need it to be lightweight and easy to pack. So far this has filled the bill very nicely! Also big kudos to Tripplite tech support, who set us up with this unit.

I discovered that the hard way when it didn't work during a power outage. Tripp-lite, how about some smart status notifications?

    Rated 5 out of 5 by from Great Customer Service I had a problem. During a lightening storm, we did not loose electricity to the house, but the TrippLite battery backup turned itself off, and my connected NAS died (totally unresponsive to pressing the power button to turn it on). TrippLite Customer Service was excellent. They were very helpful, clear, and communicative about the assessment and warantee process. Their followup through the process was excellent. I wish the customer service at other companies was great like theirs. Its nice to use good products and know that the company will professionally stand behind them when there is an issue.

    Rated 5 out of 5 by from Good Product I use this in the office, we are in a area prone to lightening strikes, and my office in particular has weird electrical issues that make me nervous to have my PC plugged into the wall directly and this is exactly what I needed for piece of mind and to protect the company's fixed assets. I know it works because I have been able to save my work and power down the PC during a power outage already, and I can hear the surge protection kicking in (it BEEPS loudly) when I use a laser printer (NOT plugged into the surge protector at all, it's plugged into a completely different outlet in my office) which means it is protecting some type of weird electrical surge in the wiring in my office -- Definitely worth the investment by far.

We have a lot of short power outages where I live and it has already maintained power to my internet router and printer during two brief outages. No interruption in internet, and no rebooting of the printer! Highly recommended for devices with relatively small power needs (sizing your UPS correctly is important).

    Rated 5 out of 5 by from Compact UPS with well-spaced power outlets. I purchased the UPS to keep our fibre-optic modem, internet router and wireless up and running during power failures. My previous UPS only kept the modem running for 20 min, so it was time for an upgrade so we can surf in the internet in the dark on our phones! What I like about this is the small footprint. It has well-spaced 3 outlets for my fibre-optic modem, my internet router and my wireless router to run on battery power when the electricity is out. The other 3 similarly well-spaced outlets are just current surge-protected and cuts power when there is no electricity. The later run my network switches and other electronic devices which are not needed in the event of a power failure and in fact, I do not want them to draw on precious battery power.
