Martek Power UK has added the MBRH series to its Powertron family of railway standard DC/DC modules.

The MBRH series takes the output power up to 25W while retaining the same physical envelope and mechanical platform as existing 15W models.

Martel said its use of the latest manufacturing techniques at its UK facility allows it to offer the MBRH high-power modules at the same cost as the lower-power MBR models.

The MBRH units are fully encapsulated DC/DC converters available in single- and dual-output configurations with outputs available from 5V to 48V.

All models meet applicable railway industry standards: RIA, EN50155 and EN50121.3.2.

Unlike competitive modules, the MBRH units require no additional external components for EMI filtering and 10ms EN51055 S2 hold up time.

A variety of mounting options, including PCB and DIN rail, can be made available, but Martek believes that the bulkhead option with the use of zero-halogen flying leads will provide most popular.

The company will further extend the MBRH series with the introduction of a 230VAC input version of the 25W module during quarter two 2010.
