The chassis mountable RMD300 series DC/DC converter is designed for railway rolling stock and transportation applications and is compliant with all relevant standards: EN50155, EN50121-3-2, DB-EMV06, EN50124-1, EN50125-1, EN61373 1B, EN62368-1, EN45545-2. The unit is designed with 12:1 input voltage range to cover the input voltages from 14.4VDC up to 170VDC for nominal 24, 36, 48, 72 and 110V in one range with isolated and regulated 24V output and reinforced isolation system. 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 and efficiency of up to 94.8% round up the functionality of this fully railway compliant Plug&Play unit.
