Martek Power To Showcase New Railway Power Supply Products At InnoTrans 2010

The MBRH series extends the established and highly popular 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 5 to 48V. All models meet applicable railway industry standards – RIA, EN50155 and EN50121.3.2 and, unlike competitive modules, 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.

Another successful range that has been expanded is the JL series. 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 just 115 x 85 x 22mm, which is less than half the overall size of the original units making them ideal for customers wishing to install a converter in their equipment and where space is limited. For chassis mount applications, an enclosed version is also available. The JLM & JLHM series are available with output voltages from 5 to 110V and all the typical railway input voltages are catered for.
