Absopulse Electronics’ BAP 236R-EH Series is a rugged, plug-in (Eurocard) DC/DC converter designed for railway and other harsh-environments. This 200W unit utilizes field-proven topology to deliver any DC output up to 130Vdc. It can be operated from supply voltages of 24Vdc ((14.4–37V), 36Vdc (22–55V), 48Vdc (28V-74V), 72Vdc (42V-110V), 96Vdc or 110Vdc (57V-168V). Other inputs are available on request. A built-in redundancy diode allows for parallel connection to achieve higher output power or N+1 redundancy.

The BAP 236R-EH is designed to meet the requirements of EN 50155 for electronic equipment used on railway rolling stock. It also meets EN 55022 Class B EMI and EN 50121-3-2 (EMI and EMC). The series is rated for operation over a -25 to +70oC temperature range without derating, with natural convection cooling. It features full electronic protection on the input and output, an optocoupler alarm output and optional control input.

This compact plug-in module measures 3U x 14HP x 220mm and is typically used in 19” rack-mount applications. The BAP 236R-EH is heavily ruggedized and conformal coated and designed to meet IEC 61373 Categories 1 A & B shock and vibration standards.
