The RPA60-FW series are high power density, wide input voltage range 60W DC/DC
converters in an industry standard 2”x1” case size. Despite their small size, the RPA60-FW converters
are fully specified devices with output currents up to 12Amps, up to 93% efficiency, no minimum load,
UVLO, 1500VDC / 1 minute isolation, tight regulation and low ripple/noise figures. The trimmable
outputs are also fully protected against over-temperature, short circuits, overcurrent and overvoltage.
The converters are UL/IEC/EN60950 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
RPA60-FW 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.
