The uninterruptible power supply ( UPS ) is the linchpin of the critical energy system, providing battery backup and power conditioning that increases availability and system performance.

Power protection from the desktop to your entire facility
From desktop to rackmount to room systems, no one delivers power protection with more reliability and flexibility than Emerson Network Power and its Liebert family of UPS (Uninterruptible Power Supply) products.

Liebert UPS systems are available in a wide range of sizes so they can be matched to the exact needs of the application. This eliminates the undersizing that can reduce reliability and the oversizing that can add to costs. When you need to grow your system, Liebert technology gives you unique ways to expand your systems, including software-based scalability and uneven paralleling.

Liebert technologies are available in passive standby, line interactive and double conversion topologies to meet the requirements of any application.

Online double conversion systems provide better protection than other types of UPS because they completely isolate sensitive electronics from the incoming power source, remove a wider range of disturbances and provide a seamless transition to battery power. Always the preferred choice for the data center, double conversion systems are increasingly displacing other types of UPS in network access rooms as overall network availability requirements rise.

Liebert UPS systems are marketed under the Liebert PowerSure, Liebert GXT, Liebert Nfinity, Liebert Npower, Liebert NX, and Liebert 610 product names. Emerson complements its UPS solutions with a family of static transfer switches, control cabinets and load balancing systems that support redundancy in high availability power systems.
