RPA40-11015SFR is a RPA40-FR series wide range input DC/DC converter especially designed for railway applications and are EN45545-2, EN50155, and UL/EN/IEC 62368-1 certified. With an input voltage range from 36 to 110VDC and a reinforced isolation barrier rated up to 3kVAC/1min, these high power density converters in a 2" x 1" case are particularly suited for rolling stock rail applications. Despite their small size, the RPA40-FR converters are fully specified devices with output currents up to 8 amps, up to 90% typical efficiency, no minimum load, UVLO, tight regulation, and low ripple/noise figures. The trimmable outputs are also fully protected against over-temperature, short circuits, overcurrent, and overvoltage.
