Eaton 3S 550VA

Product Description

The Eaton 3S 3S550I from Specialist Power Systems helps to protect your computer equipment in case of everyday events such as lightning strikes, storms, over-demand on the utility grid, accidents, and natural disasters knocking out power without warning.

The Eaton 3S 3S550I offers affordable and reliable UPS protection with 550VA/330W of backup against the most common power quality problems for office and home computers. With an attractive design and glossy finish, the Eaton 3S fits easily into any office or home environment.
In the event of a total blackout, the unit provides sufficient battery backup time to last through most power outages protecting telephone, broadband and Ethernet lines from “back door” power surges. The shutdown software makes it possible to automatically save your work and shut down your application without losing any data. Once the power is restored, you can continue working exactly where you left off. 
The 3S range comes with 8 IEC outlets for easy connection of typical computer configurations with peripherals plus it also features a HID-compliant USB port (cable supplied), for automatic integration with common operating systems (Windows/Mac OS/Linux).
