Each series has three 4:1 input voltage range options to cover all input voltages from 9VDC up Half Brick to 160VDC with isolated and regulated 5V to 48VDC outputs. The converters have high efficiencies and metal baseplates to permit a wide operating temperature range from -40C to +85C (when mounted on a suitable Single Output 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 EN50155, UL60950 and IEC/EN60950 certified. The RP75H-RW series have a three year warranty. Selection Guide (1) (1) Part Number Input Output Output Input Output Efficiency Max.
