Tripp Lite INTERNET550U 550VA UPS 300W Battery Backup Surge Protector
A brownout or sudden drop on the utility line should not drop your workstation mid-sentence. We built this compact black unit to step in the instant line power falters, keeping connected hardware alive until you can save files and complete an orderly shutdown. The rest of the time, it cleans line noise before it reaches sensitive electronics.

How this one is built
Split outlet banks
We split the rear receptacles between full battery backup and surge suppression only. That lets you reserve emergency run time for the computer, monitor, and network gear while printers or lamps use the surge side without draining the battery.
Line noise filtering
Utility lines carry electromagnetic and radio frequency interference that can disrupt sensitive hardware over time. Built-in filtering smooths out that dirty power before it reaches connected gear, alongside a resettable breaker for direct overload protection.
Status lights and alarms
Status indicators on the housing show power state, line faults, and battery health at a glance. The unit stays quiet during standard operation, sounding an audible alert only when utility power fails, the battery runs low, or a fault occurs.
Mounting and battery access
Integrated keyhole slots on the base let you mount the chassis flat against a wall or tuck it under a work surface. When the internal battery eventually reaches the end of its service life, you can swap it out yourself.
