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 resistor required or use a variable resistor to set the output voltage. Output can be externally trimmed by using the method
shown below.

Notes:
Note8: The standard module meets EMI Class A or Class B with external components.
Note9: An external input filter capacitor is required if the module has to meet EN61000-4-4 and -4-5.
The RP40-24xxFR requires an aluminum electrolytic capacitor (Nippon chemi-con KY series, 220µF/100V) and a TVS (SMDJ58A,
58V, 3000Watt peak pulse power) connected in parallel.
The RP40-48xxFR requires an aluminum electrolytic capacitor (Nippon chemi-con KY series, 220µF/100V) and a TVS
(SMDJ120A,120V, 3000Watt peak pulse power) connected in parallel.
The RP40-110xxFR requires 3pcs aluminum electrolytic capacitor in parallel (Ruby-con BXF series, 68µF/200V) and two TVS
(SMDJ90A, 90V, 3000Watt peak pulse power) in series, connected in parallel.
