railway dc-dc converter convection cooled 1kW

This series of rugged DC-DC converters is designed for an operating life of up to 20 years in railway environments. This design eliminates optocouplers in the feedback loop, which contributes to an MTBF of over 175,000 hours at 45°C. Very low component count, large design headroom, and full electronic protection also contribute to the long operating life of the units.
