High Voltage DC/DC Converter & Battery Starter

This product is available from Milexia UK

This new solution from Premium PSU, the CVS-280 series offers a wide input voltage range from 400 to 1100Vdc and has been primarily planned to support battery starting applications in the railway sector.

It has been designed to operate directly from the main catenary line when batteries discharge and use it to start the train, avoiding all hazards related to starting a light rail or trams’ battery. It also minimizes maintenance costs and optimizes repairs.

This DC/DC converter meets the requirements of EN50155 (electronic equipment for rolling stock applications), EN50163 (railway applications – Supply voltages of traction systems), EN50121-3-2 (railway applications – electromagnetic compatibility) and EN45535 (fire protection on railway vehicles).

In addition to the wide continuous input range, the CVS-280 includes an innovative active catenary filter that protects itself from surges up to 3kV. The devices are available with 24V, 36V, 72V or 110V outputs and can be connected directly to battery terminals for battery charging applications.
