Eaton 93E Series 20kVA 18kW 3 Phase Online Tower UPS
Description
The Eaton 93E UPS is a three-phase, true online double-conversion UPS system designed to protect larger IT loads and industrial equipment from power disturbances (brownouts, surges, outages, etc.). It’s engineered for reliability, efficiency, and scalability in demanding environments like data centers and enterprise facilities.
With internal batteries that provide up to 21 minutes of runtime and a 7 percent higher efficiency rating than competitive units, the 93E UPS maximizes the protection you get for every square foot of floor space and every utility dollar you spend. A detachable maintenance bypass with a mean time to repair of <30 minutes and enhanced management and monitoring capabilities from Brightlayer Data Centers’ suite increase the reliability of the system and the amount of control you have without even setting foot in the data center.
