300W, Rugged DC/DC Converter with built‐in RIA 12 Protection for Railway Applications
BAR 65 Series
The BAR 65 Series rugged, railway quality DC/DC converter uses field proven topology to generate 300W output power. This design meets the requirements of EN50155 for electronic equipment used on railway rolling stock and has the input voltage surge withstand capability to meet RIA 12 (3.5Vn for 20msec). Cooling is via baseplate to a heat‐sinking surface and by natural convection. Ruggedizing and conformal coating provide additional immunity to shock, vibration and humidity. An optional redundancy diode allows parallel connection to achieve higher output power or N+1 redundancy. Other options include a Form C output fail alarm and remote shutdown. Low component count, large design headroom, and the use of components with established reliability result in a high MTBF. The unit meets the requirements of EN50155 for electronic equipment used on rolling stock. The BAR 65 is manufactured at our plant under strict quality control. Customized versions are also available.
