Emerson Network Power Increases Capacity and Flexibility of UPS

Emerson Network Power announced a new higher-capacity version of the Liebert GXT UPS. Configurable as a tower or rack-mount model, the 10kVA Liebert GXT delivers online double-conversion UPS protection for up to 8,000W of equipment in just 6U of rack space. Paralleling capabilities allowing multiple units to work together to deliver 16,000W of protection for high density racks are scheduled to be available toward the end of 2006.

The higher capacity and increased flexibility of the new Liebert GXT increase the ability of IT and network managers to adapt to the requirements of new applications. VoIP and Power over Ethernet (PoE), in particular, are driving power and availability requirements to unprecedented levels in network closets and equipment rooms. Paralleling capabilities available toward the end of 2006 will allow the GXT to be configured as a 16kW system, or as 1+1 or 2+1 parallel redundant system.

"Network convergence is driving increased power requirements and higher availability levels for IP switches in network closets and equipment rooms," said Kevin McCalla, Liebert Marketing Director, Uninterruptible Power Systems. "The Liebert GXT provides our customers with the power to meet those requirements by combining the high availability of online double conversion technology with the flexibility of Liebert Adaptive Architecture™."

Additional product features of the Liebert GXT include: the device automatically detects the input phase angle and adapts the output voltage to 208/120 or 240/120 Vac without the need to select any voltage taps. An integrated maintenance bypass function in the 6U cabinet allows complete removal of the power module and battery modules for service or maintenance. It also allows the UPS to support the critical load without having to transfer to battery, extending system availability for when battery back-up is truly needed. Furthermore, it detects and matches line input frequencies of either 50 or 60Hz, and automatically tests unit electronics and batteries to simplify maintenance and troubleshooting. It also automatically detects connection of extended battery cabinets and adjusts the reported battery runtime based on the number of extended battery cabinets installed.
