Output Voltage Trimming
RPA100H-RUW 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.

TRIM UP
Trim down:
Vout = 24V,
DVout = -8% (22V)
Trim Up:
Vout = 12V,
DVout = +10% (13.2V)
