The half-brick RP75H 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 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 -40°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 EN50155, UL60950 and IEC/EN60950 certified.
The RP75H-RW series have a three year warranty.

OUTPUT VOLTAGE TRIMMING
Output Voltage Trimming
RP75H-RW converters offer the feature of trimming the output voltage over a certain range around the nominal value by using external trim
resistors. The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may
slightly vary; they also can be calculated with below shown equation.

An external input filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5.
The 24Vin and 48Vin version recommend 2pcs of aluminium elecrolytic capacitor to connect in parallel.
Recom suggest: 220µF/100V.
The 110Vin version recommend 2pcs of aluminium electrolytic capacitor to connect in parallel.
Recom suggest: 150µF/200V
