Output Voltage Trimming

Single output Powerline Plus 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.
