Notes:

Note9: For the single output: Maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is

not being use, the +Sense should be connected to its corresponding +Vout and likewise the -Sense should be

conneted to its corresponding -Vout.

Note10: The dual output required a minimum loading on the output to maintain specified regulation. Operation under no-

load condition will not damage these devices, however they may not meet all listed specification

Note11: Load regulation for dual output: Min load to 100% load balanced on all outputs.

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.
