New models to rail DC-DC converter module family ideal for rolling stock applications

Artesyn Embedded Technologies has 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 9VDC to 36VDC, 18VDC to 75VDC or 40VDC to 160VDC. Encapsulated in a 1” x 2” DIP package, the ERM family is protected from atmospheric conditions without additional conformal coating. The DC-DC converter modules have a wide operating temperature range of -40C to 85C 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 ideal for rolling stock applications such as engine management, traction control, door control, video surveillance, communications, entertainment, lighting and other on-board electrical equipment.
