The output current limit can be programmed using a 0-5 Vdc or 0-10 Vdc external voltage
source. Selection of the programming voltage is done using switches SW1-1 and SW1-2 as
indicated below:

To remotely program the output current limit, set switches SW1-1 and SW1-2 as shown above,
remove the jumpers connecting pins 10 to 11 and 22 to 23 of connector J3 and connect the
external voltage source between pins 10 (positive) and 12 (return). Varying the voltage source
from 0-100% causes the current limit to vary from 0-100% of the rated maximum.

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.
