600-Watt Regulated Quarter Brick Bus Converters can be Paralleled

GE's Critical Power business introduced its new QBVE060A0S10R4 625-W and the QBVS050A0B 600-W, quarter-brick bus converters. These new modules are part of the company’s Barracuda product series of fully-regulated dc-dc power devices. Each of GE’s new bus converters improve power density by more than 50 percent compared to industry-standard 400-W bus converters. In addition, the new bus converters deliver highly efficient power to the load, with efficiencies exceeding 96 percent. The QBVE060A0S10R4 and QBVS050A0B fully-regulated bus converters provide efficient, reliable power for servers and routers as well as for high-bandwidth streaming applications such as fourth-generation long-term evolution (4G LTE) wireless networks, 100-gigabyte dense wavelength division multiplexing (DWDM) optical networking infrastructure, high-density integrated circuit test equipment and network monitoring and security equipment.

Key features and benefits of the QBVE060A0S10R4 625-W and QBVS050A0B 600-W bus converters include: Designed to support intermediate bus applications where multiple low voltages are generated using point of load converters. Original equipment manufacturer (OEM) designers realize improved power density with minimal board real estate. Fully-regulated devices support distributed power architectures, intermediate bus voltage applications, fan assemblies and other systems requiring tightly-regulated output voltages. The QBVE060A0S10R4 625-W bus converter operates within a 45- to 56-Vdc input range, delivering 10.4Vdc. The QBVS050A0B 600-W bus converter operates within a 52- to 60-Vdc input range, delivering 12Vdc. Modules can be paralleled in sets of three for higher-power applications.
