DC/DC Converter
RP90Q-RW
90 Watt
Quarter
Brick
Single Output
The quarter-brick RP90Q 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 base-
plates 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 and IEC/EN60950 certified. The RP90Q-RW series have a
three year warranty.

OUTPUT TRIM
Output Voltage Trimming
It allows the user to increase or decrease the output voltage of the module. This is accomplished by connecting an external resistor between the Trim pin and
either the +Sense or -Sense pins. With an external resistor between the Trim and +Sense pin, the output voltage increases. With an external resistor between
the Trim and -Sense pin, the output voltage decreases. The external Trim resistor needs to be at least 1/8W of rated. The values for trim resistors shown in trim
tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.
