Features Regulated Converter 4:1 wide input range 3kVAC reinforced insulation for 11Vin 2.25kVDC basic insulation for 24Vin & 48Vin Efficiency up to 91% No minimum load required UL695-1, EN5155 & IEC/EN695-1 certified DC/DC Converter RP24H-RW Description The half-brick RP24H series DC/DC converters are designed for railway rolling stock and high voltage battery applications. Each series has three 4:1 input voltage range options to cover all input voltages from 9VDC up to 16VDC with isolated and regulated 5V to 48VDC outputs. The converters have high efficiencies and metal baseplates to permit a wide operating temperature range from -4 C to +85 C (when mounted on a suitable heatsink). 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 converters are EN5155, UL695 and IEC/EN695 certified. The RP24H-RW series have a three year warranty. 24 Watt Half Brick Single Output Selection Guide Part Number Input Output Output Input (1) Output Efficiency (1) Max.
