Emerson Network Power introduced the latest addition to its line of Liebert uninterruptible power supply (UPS) systems for large facilities Thursday.


The Liebert eXL 800kVA/kW is a large transformer-free single-module system designed for colocation and large enterprise data centers. It runs at 96% efficiency at full load in double-conversion mode, according to the vendor.


Emerson said the product is 10% smaller than competitive systems and delivers 17% more power density per square foot. It integrates seamlessly with the company's data center infrastructure management (DCIM) platform Trellis.


Peter Panfil, VP of global power at Emerson, said that while high availability was still a priority for most data center operators, more and more of them are looking at efficiency performance of UPS systems to reduce operational and capital cost.


“With high operating efficiency, smaller footprint, higher power density, optimal power delivery, scalable architecture and lower installation cost, the Liebert eXL 800kVA UPS is an ideal solution for data centers where maximum efficiency through low TCO might take priority,” Panfil said.


While currently available only as a single-module system, multi-module configurations of eXL will be available in the fall of 2014, according to Emerson's website.


This is the seventh product in Emerson's portfolio of large-facility UPS systems. It is available in the Americas for 480V, 60Hz applications.
