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:
Note7: The 24VDC & 48VDC input standard modules meet EN55022 & EN55011 Class B with just an input capacitor,
the 110VDC input module meet EN55022 Class A with an input capacitor and Class B with an EMC Filter.
Note8: An external input filter capacitor is required if the module has to meet EN61000-4-4, -5.
The filter Recom suggests: 24VDC and 48VDC input.Nippon chemi-con KY series, 220µF/100V.
