2.11.2 Programming With an External Resistance
The output voltage and current limit can be programmed using a 5k ohm external potentiometer.
To program the output voltage, set switch SW1-3 open (default factory setting) and 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.
