Power solutions specialist Murata has announced the RBE series of fully isolated dc/dc converters.

The modules are designed for a range of applications, including 12VDC intermediate bus architectures or distributed power based applications used in servers, wireless base stations, data storage, telecom switches and networking equipment. The RBE-12/20-D48 model offers a regulated 12V output at 240W from a nominal 48VDC input and an efficiency of 94.5%. For applications where there is no forced air cooling or the operating temperature range is high, an optional baseplate is available that will allow for attaching a heat sink. The RBE dc/dc converter has been designed to meet the requirements of the Distributed power Open Standards Alliance (DOSA) eighth brick configuration measuring 58.42 x 22.86 x 10.16mm. The standard module is a through hole mounted package, configured as an open frame converter with 4.6mm pins and negative logic. Optional configurations include various pin lengths to eliminate secondary process for trimming pins, positive logic control, conformal coating and the base plate for conduction cooling applications. Protection features include thermal shutdown with auto restart (hiccup), over current/short circuit protection with auto restart, and input under voltage lockout. The converter is fully isolated to 2250VDC with a basic insulation system meeting the requirements for PoE applications and is compliant with the internationally recognized safety standards UL/EN/IEC 60950.
