ABSOPULSE Electronics’ RWR 155 series of fully encapsulated railway quality dc-dc converters deliver up to 150W output power
They meet the requirements of EN50155, and with an input voltage surge withstand capability of 385Vdc for >1 second (3.5Vn for 20msec min.), they meet also RIA12. The converters accept 24Vdc, 36Vdc, 48Vdc, 72Vdc, 96Vdc or 110Vdc with wide EN50155 input ranges. They deliver a single, regulated output of 12V, 24Vdc, 48Vdc or 110Vdc. The units are fully encapsulated with a thermally conductive MIL-grade silicon rubber compound with a UL94V-0 flammability rating and meet environmental criteria as requested in MIL-810C, D. Cooling by conduction and convection enable operation over a -40°C to +70°C for full specification.
