It's easy to think of UPS battery backup systems as products intended for use with home theater systems, PC systems and servers. But what happens when you have a remote area that houses your routers and cable modem? For this, Tripp Lite presents their AV50SC, a 300W (550VA) device with 4 outlets that provides basic battery backup protection for your cable modem, router, switch and/or other devices that are just as important to your home theater or office setup, but don't necessarily require a fancy box and tons of power output.
