The chassis mountable RMD500 series DC/DC converter is designed for railway rolling stock and transportation applications. The unit is designed with 4:1 input voltage range to cover the input voltages from 43.2VDC up to 170VDC for nominal 72V and 110V in one range with isolated and regulated 24V output, based on a reinforced isolation system. The converter has a constant and high efficiency of 95%, and the base plate mounting permits a wide operating temperature for OT4+ST1&ST2 class from -40°C to +85°C without derating. Input reverse polarity protection, inrush current limitation, 10ms hold-up time, remote control, and output OR-ing diode round up the functionality of this fully railway compliant Plug&Play unit.
