Murata has announced the 1 kW DRQ-11.4/88-L48 series of quarter brick, intermediate bus, DC/DC converter modules that address the growing power requirements of high-reliability networking and telecommunications infrastructure equipment. The fully regulated DRQ-11.4/88-L48xx Series provides 11.4Vout at 88 A, with a Vin Range of 36 to 60Vdc, operating from 48Vdc battery systems or networking equipment that operates at 54Vin. This fixed frequency, 1 kW rated bus converter boasts an industry leading efficiency level of 97%.

Developed by Murata Power Solutions to the industry standard DOSA high power 1/4 brick specification, the DRQ-11.4/88-L48xx DC-DC converter modules are available with many standard features including parallel load sharing of two or more modules, pre-bias protection, positive or negative on/off logic options, short circuit protection, over current/voltage and over temperature protection. The DRQ-11.4/88-L48 Series supports pre-biased start-up, eliminating reverse current issues during system start and shutdown.

Safety rated for networking and telecommunications applications; the fully isolated modules provide 1,500 Vdc of Input / Output isolation with an operational insulation safety rating. In order to provide industry leading reliability, the DRQ-11.4/88-L48 Series is designed and tested to meet the requirements of IPC-9592 Revision B. The converter's integrated baseplate design enhances thermal performance and its 97% efficiency promotes cooler operation for reliability and longevity.

The primary applications for Murata Power Solutions' DRQ-11.4/88-L48 are networking and telecommunications infrastructure equipment, communications equipment, network security, routers, wireless base stations, telecommunications switches and electronics, computing equipment and other applications requiring power conversion to an intermediate bus voltage of 11.4 V.
