1. Remove the jumpers connecting pins 10 to 11 and 22 to 23 on connector J3.
2. Connect the external programming source between pins 10 (current limit programming
input/positive) and 12 (return).
Varying the programming voltage from 0 to 5 Vdc will cause the current limit to vary from 0 to
100% of the model rating. The output voltage is set locally by adjusting the front panel voltage
control.

1. Set jumper JMP2 to its A-B location.
2. Remove the jumpers connecting pins 10 to 11 and 22 to 23 on connector J3.
3. Connect the external current programming source between pins 10 (current limit
programming input/positive) and 12 (return).
Varying the programming voltage from 0 to 10 Vdc will cause the output current limit to vary
from 0 to 100% of the model rating. The output voltage is set locally by adjusting the front panel
voltage control.
Note: Resetting internal jumpers may require a recalibration of the programming circuit to
maintain programming accuracy. See Section 6.3 Calibrating for Programming
Accuracy.
