4 / 8 page PD-4 REV.: 0/2016 www.recom-power.com DC/DC Converter Specifications measured at Ta = 25°C, nominal input voltage, full load otherwise noted RP20-FR Series External Output Trimming TRIM UP TRIM DOWN Output Voltage Trimming Single output Powerline converters offer the feature of trimming the output voltage over a certain range around the nominal value by using external trim resistors. No general equation can be given for calculating the trim resistors, but the following trimtables give typical values for chosing these trimming resistors. If voltages between the given trim points are required, extrapolate between the two nearest given values to work out the resis tor required or use a variable resistor to set the output voltage. Output can be externally trimmed by using the method shown below.
