DC/DC converters on the rails
17 August 2010
Martek Power will showcase several new railway qualified products at InnoTrans.
Martek’s MBRH series extends the established 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.
In addition, the new JLM and JLHM units are rated at 35W and 50W respectively, and offer all the features and benefits of the standard range, including full EN50155 compliance, but in a much smaller footprint. The open frame version of both products measures 115mm x 85mm x 22mm, which is less than half the overall size of the original units, making them suitable for customers wishing to install a converter in their equipment where space is limited. For chassis mount applications, an enclosed version is also available. The JLM & JLHM series are available with output voltages from 5V to 110V and all the typical railway input voltages are catered for.
InnoTrans, the international show for railway technology, takes place next month in Berlin.
