200W, DC-DC Railway Converter in Plug-in (Eurocard) format for 19″ Rack-mount applications

The BAP 236R-EH series of railway DC-DC converters in plug-in (Eurocard) format are designed for  19″ rack-mount applications. The 200W units employ field-proven topology to deliver any DC output up to 130Vdc. They operate from railway supply voltages of 24Vdc (14.4–34Vdc range), 36Vdc (22–51Vdc), 48Vdc (29V-67Vdc), 72Vdc (43V-101Vdc), 96Vdc (58 – 135V) or 110Vdc (66-154Vdc). Other inputs and outputs are available on request. A built-in redundancy diode allows for parallel connection to achieve higher output power or N+1 redundant operation, including hot-insertion.

The BAP 236R-EH railway converters meet the requirements of EN50155 for electronic equipment used on railway rolling stock. They have heavy filtering on the input and output and comply with EN50121-3-2. The converters also meet EN61000-4-2, EN61000-4-3, EN61000-4-4 and EN61000-4-6. Full electronic protection includes 3000Vdc input-output isolation, overload protection, thermal protection and current limiting.

The series is rated for operation over a -25 to +70oC temperature range without derating, with natural convection cooling. Heat generating components are installed on an aluminum heatsink block, which is connected to the heatsink plate on the side of the module. This also provides exceptional mechanical ruggedness. This compact plug-in module measures 3U x 14HP x 220mm and is typically used in 19” rack-mount applications. The BAP 236R-EH converters are heavily ruggedized and conformal coated and meet IEC 61373 Categories 1 A & B shock and vibration standards.
