DC/DC Railway Converter with Wide Input Voltage Ranges in Eurocard (Plug-in) format for 19" Rack-mount Applications

Absopulse Absopulse Electronics’ DCW 100R-EH Series is a plug-in dc/dc converter with wide input ranges designed for railway and other heavy-duty applications. It can be operated from 48Vdc (28V to 74Vdc range), 72Vdc (42V to 110Vdc), 96Vdc or 110Vdc (57V to 168Vdc) supply voltages. This 100W field-proven converter provides output voltages of 12V, 24V, 48V or 110Vdc. Other input and output configurations are available on request.

The DCW 100R-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 unit features full electronic protection on the input and output, high efficiency and reliability.

This compact plug-in module measures 3U x 10HP x 160mm is mostly used in 19” rack-mount applications. DCW 100R-EH is heavily ruggedized and conformal coated and designed to meet IEC 61373 Categories 1 A & B shock and vibration standards. Cooling is by natural convection and it performs to full specification at temperatures from
-25°C to 70°C (Class T1).
