DC/DC converters

Our DC/DC converters are fitted and used on rolling stock (trains, metros, ...) all over the world and comply with the most severe technical constraints in terms of noise, electromagnetic compatibility (EMC), residual ripple, high efficiency, operating temperature range, insulation level, ... and more generally our converters are adapted to the specific standards and specifications imposed by the railway sector.

Our wide range of DC/DC converters can supply any type of load requiring a constant and stable DC supply voltage, such as LED modules, LED cards, various electronic cards, halogen spotlights, etc.

The current power range extends from 5 to 200W.
