Martek Power has expanded its Powertron range of DC/DC converters designed specifically for railway applications such as on-board passenger information systems.

The converters are extensions to Martek’s JL series of open frame units.

The JLM and JLHM converters are rated at 35W and 50W respectively and offer all the features and benefits of the standard range – including full EN50155 compliance – in a smaller footprint.

Both JLM and JLHM units can accept the wide range of typical railway input voltages and outputs can be specified between 5 and 110VDC.

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

Martek said this makes the power supply ideal 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.

Martek Power designs and manufactures a wide range of standard and custom AC-DC power supplies, DC-DC power converters, DC-AC power inverters, EMI filters for Military, Aerospace, Medical, Railway, Automotive, Computing, Data storage, Telecom, Laser, Lamps, Networking, and many other industrial applications. Product output power ranges from 1 to 50,000 watts.
