Absopulse Electronics' RWR 212 is a 200W DC/DC converter for electronic equipment used on railway rolling stock and other extreme environments.
The RWR 212 offers high levels of isolation and has a built-in voltage limiter circuit to ensure input voltage surge and transient withstand capability to meet RIA 12 (3.5Vn for 20msec).
It meets EN 50121-3-2 (EMI and EMC) and EN 55022 Class B EMI performance requirements.
This converter operates from 24VDC (14.4 - 37V), 36VDC (22 - 55V), 48VDC (28 - 74V), 72VDC (42 - 110V), 96VDC or 110VDC (57 - 168V) supply voltages and uses push-pull topology to deliver 12V, 24V, 36V and 48VDC.
Housed in a 3.7 x 2.4 x 9in enclosure, this converter is potted in a thermally conductive MIL-spec silicon rubber compound to ensure immunity to humidity and moisture.
It meets IEC 61373 shock and vibration standards as well as those specified in RIA 13 and RIA 20.
The RWR 212 is also designed for continuous operation at full specification from -40C to +70C cold plate temperature.
