Emerson Network Power Extends Midsize UPS Product Line With Native 480V
Emerson Network Power has introduced five capacities of the Liebert eXM Uninterruptible
Power Supply (UPS) system for native 480V AC configurations. The new models address
critical applications with medium power 480 V requirements, while providing cost control,
efficiency and speed of deployment. The new 480 V AC models are available in 50 to 250
kVA/kW in the Americas.
"With the addition of the new 480 V AC models, the Liebert eXM UPS family now includes
models ranging from 10 to 250 kVA/kW and includes a comprehensive portfolio of native
208 V, 220 V,and 480 V products. Each offers a high efficiency solution for midsize data
centers supporting bigger loads," said Steve McKinney, vice president, general manager of
power management for Emerson Network Power. "This UPS family meets the need for solutions that deliver lower first costs and ongoing operational savings, while allowing for flexibility and shorter deployment schedules in a dynamic IT environment."
The Liebert eXM UPS family includes flexible, optimized ancilliary cabinets. These include options for extended battery, maintenance bypass, distribution, transformer and paralleling.
All models of Liebert eXM UPS offer high operational and cost efficiencies. The ENERGY STAR qualified UPS delivers
among the highest efficiency levels for midsize power applications. During double conversion mode, the transformer-free Liebert eXM UPS delivers up to 97 percent efficiency. When operating in energy-saving Eco-Mode, efficiency
increases up to 99 percent. In addition, the unity power factor design delivers the highest level of power capacity, reducing cabling and installation costs compared to non-unity designs, and saving more than 30 percent in floor space
over comparable configured systems.
All Liebert eXM UPS models can incorporate the integrated Alber battery monitoring option, which improves the
reliability of backup batteries through continuous testing and reporting. Also available, the exclusive LIFE Services
which provides robust lifecycle management via continuous remote diagnostics and proactive service dispatch.
Customers can depend on experts who are prepared to interpret advanced service level data using IP-based communications to anticipate, identify, diagnose and respond to problems before they can cause downtime or hinder
GE Introduces Latest Barracuda-Series DC-DC Converters
GE's Critical Power business has launched its Barracuda-seriesT QBVE094A0S10R7
1,000-watt (W) DC-DC bus converters, providing a power density and lowest costper-rated-watt in a quarter-brick solution. The modules offer 20 percent more
power than standard 800-W solutions.
The QBVE094A0S10R7 DC-DC converters feature an operating input voltage
range of 45-56 volts DC and provide up to 1,000 W output power at output voltages of 10.7 volts. When used in parallel configurations, the QBVE094A0S10R7
converters can deliver 1,800 W output power with two modules or 2,700 W
power with three units. This is particularly useful in high-end networking and
software-defined network applications where one switch is expected to serve many configurable functions.
"In almost any electrical application, achieving more power in less space is a major design challenge. Take large,
hyper-scale data centers for example," said Karim Wassef, general manager - embedded power product line, GE's
Critical Power business. "In these facilities, device and rack-level densities are critical to optimizing operation. Our
high-power, Barracuda-series QBVE094A0S10R7 DC-DC converters provide a power density and configuration flexibility that enables board engineers to design in the negative space."
GE's high-power, PMBus-equipped Barracuda-series DC-DC converters can support 10.7-volt intermediate bus applications where multiple low voltages are subsequently generated using point-of-load modules. Its load-share feature
