Martek Power has added to its Powertron family of  DC/DC converters.

The JL series of open frame units were originally designed for on-board passenger information systems.

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