The RPA20-FR series wide range input DC/DC converters have been 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 160VDC and a reinforced isolation barrier rated up to 3kVAC/1min, these high power density converters in a 1.6“ x 1“ case are particularly suited for rolling stock rail applications. Despite their small size, the RPA20-FR converters are fully specified devices with output currents up to 4 amps, up to 90.5% 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, over-current, and over-voltage.
