4:1 wide input range 3kVAC reinforced insulation for 11Vin 2.25kVDC basic insulation for 24Vin & 48Vin Efficiency up to % No minimum load required EN5155 certified IEC/EN95-1 certified Features Regulated Converter Description The quarter-brick RPQ 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 1VDC with isolated and regulated 5V to 48VDC outputs. The converters have high efficiencies and metal baseplates to permit a wide operating temperature range from - 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 and IEC/EN95 certified. The RPQ-RW series have a three year warranty.
