10W and 20W DC-DCs for Railway Applications

Artesyn Embedded Technologies today added 72 new models to its ERM family of dc-dc converter modules designed to meet the power demands and safety standard requirements of railway rolling stock applications. Covering 10W and 20W power output ratings, each series includes models with single 5V, 12V, 15V, 24V, or dual ±12V or ±15V outputs and input ranges of 9- to 36-Vdc, 18- to 75-Vdc or 40-Vdc to 160-Vdc.

Encapsulated in a 1-inch by 2-inch DIP package (25.4 x 50.8), the ERM family is protected from atmospheric conditions without additional conformal coating. The dc-dc converter modules have a wide operating temperature range of -40 to +85 degrees C with derating. An optional heat sink can help heat dissipation and improve performance at high operating temperatures.

A reinforced insulation system with 3000Vac RMS I/O isolation, combined with high EMC immunity, qualifies these new dc-dc converters for the many demanding embedded power applications in railway and other transportation systems. It is well-suited for rolling stock applications such as engine management, traction control, door control, video surveillance, communications, entertainment, lighting and other on-board electrical equipment.
