Programming Output Voltage
Programming Output Voltage with a 0-5 Vdc Source
1. Remove the jumpers connecting pins 8 to 9 and 20 to 21 on connector J3.
2. Connect the external programming source between pins 9 (voltage programming
input/positive) and 12 (return).
Varying the programming voltage from 0 to 5 Vdc will cause the output to vary from 0 to 100%
of the model rating. The output current limit may be programmed using another source or set
locally by adjusting the front panel current limit control.

Programming Output Voltage with a 0-10V Source
1. Set jumper JMP1 to its A-B location.
2. Remove the jumpers connecting pins 8 to 9 and 20 to 21 on connector J3.
3. Connect the external voltage programming source between pins 9 (voltage programming
input/positive) and 12 (return).
Varying the programming voltage from 0 to 10 Vdc will cause the output voltage to vary from 0
to 100% of the model rating. The output current limit may be programmed using another source
or set locally by adjusting the front panel current control.
Note:
Resetting internal jumpers may require a recalibration of the programming circuit to
maintain programming accuracy. See
