10:1 ultra wide input voltage range Features 4.242kVDC/1 minute reinforced insulation DC/DC Converter UL/IEC/EN60950-1 certified CE marked, CB report Regulated Efficiency up to 93% Converter -40C to +100C baseplate temperature range RPA100H-RUW Description 100 Watt The half-brick RPA100H series DC/DC converter is designed for railway rolling stock and high voltage battery applications. It has a 10:1 input voltage range to cover all input voltages from nominal 24VDC Half Brick up to 110VDC in a single product (including EN50155 transients) and offers isolated and regulated 12V, 15V, 24V or 48VDC outputs. The converter has a consistently high efficiency over the entire Single Output input voltage range and comes with a metal baseplate to permit a wide operating temperature range from -40C to +97C (when baseplate cooled). The case is fitted with threaded inserts to allow secure mounting to the PCB or bulkhead for use in high shock and vibration environments. The converter is certified to UL/IEC/EN60950 and comes with a three year warranty. Selection Guide Part Number Input Output Output Efficiency Max.
