Emerson Network Power has announced that 11 models of its Liebert® GXT3 uninterruptible power supply (UPS) earned ENERGY STAR® Version 1.0 qualification. All 11 qualified models of the Liebert GXT3 are available across North America.

The Liebert GXT3  is ENERGY STAR qualified for the following rack/tower convertible models: 120V input 700, 1000, 1500, 2000, and 3000 VA models; 208V input 3000, 6000VA models; and 120/208V input 5000, 6000, 8000, and 10000VA models . The Liebert GXT3 enables IT managers to pack higher capacities into smaller spaces while ensuring optimized efficiency. The system provides continuous uptime for the connected equipment, with capacity and battery backup delivered in compact cabinets that use 2U to 6U of rack space.

“The ENERGY STAR UPS program helps customers make informed purchasing decisions as they consider ways to efficiently design and apply UPS from small server deployments to large data centers,” said David Sonner, vice president, marketing, Emerson Network Power in North America. “The U.S. Environmental Protection Agency (EPA) has worked closely with the IT industry to identify ways in which energy efficiency can be measured, documented and implemented in data centers, and we are proud to be an ENERGY STAR partner.”

To qualify for the award, which was first instituted by the U.S. EPA in 2012, the Liebert GXT3 was subjected to testing by a UPS-specific certification body, and was examined based on average power, efficiency and efficiency variation for determination of steady-state. UPS products meeting the requirements of the U.S. EPA program use an average of 35% percent less energy than their standard counterparts.

The Liebert APM UPS also earned ENERGY STAR certification in October 2012.
