These are analog voltage inputs to the designated convert-
er modules by which the output voltage is adjusted. A zero
to + 5V input represents approximately -25 to +10% output
change for a converter. This input should be driven from a
source impedance less than 100 ohms and is referenced to
-Sense, Pin 23.
