Martek Power has announced that it will debut several DC/DC converters at Innotrans, an international show for railway applications.

The MBRH series extends the Powertron MBR series to an output power of 25W, while retaining the same physical envelope and mechanical platform as existing 15W models.

Like earlier 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 – and the MBRH units require no additional external components for EMI filtering and 10ms EN51055 S2 hold-up time.

All models are available for either PCB or bulkhead mounting.

Martek will also be exhibiting the latest products from its JL series.

The new JLM and JLHM are rated at 35W and 50W respectively and offer all of the features of the standard range, including full EN50155 compliance, but in a much smaller footprint.

The open-frame version of both products measures 115 x 85 x 22mm, which is less than half the volume of the original range.

This is suitable for customers wishing to install a converter in their own equipment where space is limited.

For chassis-mount applications, an enclosed version is also available.

The JLM and JLHM series are available with output voltages from 5V to 110V and all the typical railway input voltages are catered for.

Innotrans takes place in Berlin, Germany, from 21-24 Sep 2010.
