The RPA30-AW series are high power density, wide input voltage range 30W DC/DC converters in
an industry standard 1”x1” case size. Despite their small size, the RPA30-AW converters are fully
specified devices with output currents up to 7.5Amps, up to 89% efficiency, no minimum load, 1600VDC
isolation, tight regulation and low ripple/noise figures. The outputs are also fully protected against
over-temperature, short circuits, overcurrent and overvoltage and the single output version
offers a ±10% trim range. A heatsink option is available to extend the operating temperature range.
The converters are UL and EN50155 certified and will find many uses in railway and industrial
applications where board space is at a premium.

OUTPUT TRIM
Output Voltage Trimming
RPA30-AW 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.
