The Liebert® eXM UPS is based on a reliable, double conversion  power topology that uses an efficient transformer-free design.  Operating efficiencies as high as 96% are generated in double-conversion mode and as high as 99% using our unique Eco Mode. The unity power factor delivers more capacity in a smaller.

Scale in 20kW increments from 10-200kVA/kW (208V) or 50kW in 50-250kVA/kW (480V) utilizing a modular construction design with optimized ancillary cabinets. The new Touch-screen Control Panel uses “glove friendly” technology that is both easy to read and use to reduce errors and enhance control.

Intelligent controls and network communications integrate with Liebert Nform, SiteScan and the Trellis Platform as well as 3rd party DCIM, BMS and monitoring systems. LIFE Services provides 24x7 remote monitoring by our expert staff to improve availability and lower labor costs.
