The Liebert EXM is based on a reliable, double conversion power topology that uses an efficient transformer-free design. The equipment provides economical operation with a flexible power system. The demands of midsize IT and critical power applications are unique and the scalable and redundant features are optimized to meet those needs. The comprehensive, easy to use touchscreen control panel is intuitive and customizable. Available in a fixed capacity or a scalable, redundant configuration from 10-200kVA/kW in 208V and 50-250 kVA/kW in 480V, each utilizes a modular construction design with optimized ancillary cabinets designed to save on footprint and cost. The optimized ancillaries and unity power factor provide a smaller footprint for better use of space and lower installation costs. The Liebert EXM offers an integrated Alber battery monitoring option which can prevent pending battery issues, the most common cause of UPS failures.
Other features include: Industry leading efficiency rating: 97% for double conversion mode, and 99% for eco mode, ENERGY STAR qualified, UL924 listed for Emergency Lighting, Efficiency Winning operating efficiencies that remain high across multiple load scenarios, bypass cabinet option allows maintenance without shutting down the critical load, distribution panel board option to add more circuits, and UPSs can be paralleled to obtain more capacity or add system level redundancy.
