The RP120H series is a low cost, high power DC/DC converter in an industry standard half-brick case. The input voltage cover the range from 53V up to 154V with a 100mS surge resistance up to 250VDC and it offers regulated and short-circuit protected single outputs up to 24V. The flanged metal baseplate permits efficient cooling by mounting an external heatsink or robust shock and vibration mounting. Typical railway installations include intermediary bus power supplies (for example, dropping a 110VDC supply down to an industry standard 24V) and cost sensitive, higher volume applications which need to be built in to every passenger wagon such as passenger information displays and personalized LED lighting.
