We supply DC/DC converters, ranging from a few watts to several hundred watts, to the rail sector, both from our catalogue of standard products and specifically developed to meet specifications.

Compact, robust and compliant with EN 50155 railway standards, they are designed for on-board applications such as powering signalling systems, braking systems, and radiocommunications, ventilation and lighting equipment.

These converters are intended to be connected to the on-board power supply and offer all the necessary protection to ensure smooth operation.

Certain models offer a wide range of input voltages.
