An uninterruptible power supply is the linchpin of the data center backup chain, providing vital protection against power disruptions that would interfere with workloads or even cripple server hardware.
Today’s UPS systems offer a wealth of maintenance and management features that ensure long, reliable operation. UPS choices are vast, with a bewildering spectrum of features to choose from, but a UPS must deliver adequate power to run the load long enough to restore utility power, also called runtime, or to fully shut down. Load power is measured in watts (W) or, more accurately, volt-amperes (VA); UPS systems range from just a few hundred VA up to massive 800 kVA behemoths.
The Liebert® eXM 3-phase UPS is based on a reliable, double conversion power topology that uses an efficient transformer-free design. Excellent efficiencies of 95.4% are generated and can be enhanced to 98% using our unique Eco Mode. A unity power factor delivers more capacity in a smaller footprint.
Fixed capacities of 10, 15, 20, 30, 40, 60, 80, 100, 120, 140, 160, 180 and 200 in native 208V, plus 50, 100, 150, 200 and 250 kVA/kW in native 480V, each utilizing a modular construction design with optimized ancillary cabinets. The new LCD user interface ensures accurate interaction with the system, with a low learning curve. Intelligent controls and communications integrate with Liebert Nform, SiteScan and the Trellis Platform. Life Services provides 24×7 remote monitoring by our expert staff to improve availability and lower labor costs.
