The INTERNET350SER Internet Office® 120V 350VA 180W Standby UPS protects your PC and other expensive equipment against common power threats, such as blackouts and surges. Reliable battery 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. The internal battery provides 12.2 minutes of runtime at half load and 3.3 minutes at full load.

Three outlets provide both battery backup and surge protection to your computer, monitor and other crucial components. The other three are surge-protected only for printers, scanners and other non-essential equipment.
