Backup Power (UPS)

Eaton 9355 UPS

The Eaton 9355 UPS (formerly the Powerware 9355) is a three-phase, double-conversion online UPS that provides a complete power protection solution. In a footprint that is up to 75 percent smaller than comparable UPSs, the 9355 UPS comes complete with internal batteries, an integrated power distribution module and a maintenance bypass switch. Without the need for large external battery cabinets, it is possible to parallel up to four UPSs to build out redundancy or add capacity with less space than a typical large UPS requires, thanks to Eaton's patented HotSync paralleling technology.

Power rating
