Programming With An External Current Source - Xantrex XKW 8-125 Operating Manual

Programming
The output voltage and current limit can be programmed using an external 0-1mA
current source.
With an

Source
and 21 of connector J3. Connect the external current source between pins 8 (positive)
and 12 (return) of connector J3. Varying the current source from 0-1mA will vary the
output voltage from 0-100% of the rated output.

To program the output current limit, set the current control to maximum, set switches
SW1-1 and SW1-2 open (factory setting) and remove the jumper between pins 22 and
23 of connector J3. Connect the external current source between pins 11 (positive) and
12 (return). Varying the current source from 0-1mA causes the current limit to vary from
0-100% of rated maximum.
