• Fully railway approved for EN50155 (S2) applications • EN50121-3-2, EN50124-1, EN62368-1, EN61373, EN45545-2 • Plug&Play unit for natural convection cooling • Ultra wide range input for nominal 24V and 110V • Excellent efficiency and functionality • Parallel and redundant operation • Extremely reliable and robust Features Regulated Converter Description The chassis mountable RMD150-UW series DC/DC converter is designed for railway and transportation applications. The unit is designed with 12:1 input voltage range to cover the input voltages from 14,4VDC up to 154VDC for nominal 24, 36, 48, 72 and 110V in one range for all applications - on every vehicle worldwide. The isolated and regulated 24V output works with a reinforced isolation system. Due to the base plate mounting the unit operates with full power within the wide temperature for OT4+ST1&ST2 class from -40°C to +85°C and no addition cooling systems are necessary. Input reverse polarity protection, inrush current limitation, 10ms hold-up time, remote control, and output O-Ring diode and efficiency of up to 95% round up the functionality of this fully railway compliant Plug&Play unit.
