Industrial DC/DC converter DHR 150-F1 series

chassis-mountedregulatedfor railway applications

This rugged, industrial quality DC/DC converter is designed for an operating life extending to 30 years. By eliminating optocouplers in the feedback loop and significantly reducing the component count, the MTBF of the unit is greatly improved over conventional designs. All heat generating components are installed on aluminum heat-sink blocks which are cooled via baseplate to a heat-sinking surface and by natural convection. Conformal coating provides additional environmental protection. Large design headroom and the use of components with established reliability also contribute to the long operating life of the unit. Customized versions are available.
