Programming With An External Resistance - Xantrex XKW 8-125 Operating Manual

Operation
Remote Programming of Output Voltage and Current Limit
Programming
The output voltage and current limit can be programmed using a 5k ohm external
potentiometer.
With an
External
To program the output voltage, set switch SW1-3 open (default factory setting) and
Resistance
remove the jumpers connecting pins 8 to 9 and 20 to 21 on connector J3. Connect pins 9
and 21 to the counterclockwise end of the 5k potentiometer and connect the tap and
clockwise end of the potentiometer to pin 12. Adjusting the tapped resistance from 0-5k
will vary the output voltage from 0-100% of the rated output.

To program the output current limit, set switches SW1-1 and SW1-2 open (default
factory setting) and remove the jumpers connecting pins 10 to 11 and 22 to 23 on
connector J3. Connect pins 10 and 22 to the counterclockwise end of the 5k
potentiometer and connect the tap and clockwise end of the potentiometer to pin 12.
Adjusting the tapped resistance from 0-5k will vary the current limit from 0-100% of the
rated output.
