Operating Manual for XKW 3kW Series Power Supply
Programming Output Current Limit with a 0-10Vdc Source
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 10Vdc 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
“Calibrating for Programming Accuracy” on
page 82 .
