35W & 50W DC/DC Converters
35W & 50W DC/DC Converters for railway applications.
The new JLM and JLHM converters for railway applications 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.
