DC/DC converters suit demanding embedded power applications

The ERM family is designed to meet the power demands and safety standard requirements of railway rolling stock applications. An advanced circuit topology enables a high efficiency of up to 92%. Encapsulated in a compact quarter-brick form factor with metal base-plate, the converters are protected from atmospheric conditions without additional conformal coating being required. The isolated base-plate with threaded inserts can accept an optional heat sink or be used to cold-wall mount the new modules. The ERM family features a reinforced insulation system as required by the general specification of high voltage input and low voltage output. Combined with high EMC immunity, this qualifies the devices for demanding embedded power applications in railway and other transportation systems. The converters comply with the railway industry's EN 50155 and 50121-3-2 specifications and have been tested to the vibration and thermal shock requirements of EN 61373. They are suited to rolling stock applications such as engine management, traction control, door control, video surveillance, communications, entertainment, lighting and other on-board electrical equipment. The first two series in the ERM family, the ERM75 and ERM50, offer 75 and 50W maximum power output, respectively. Each series includes eight models with 5, 12, 15, or 24V outputs and input ranges of 43 to 101Vdc or 66 to 160Vdc.
