Operation
Remote Programming of Output Voltage and Current Limit
Revision A

Programming Output Current Limit with a 0-1mA Source
1. Remove the jumper between pins 22 and 23 of connector J3.
2. Connect the external programming source between pin 10 (current limit
programming input/positive) and pin 12 (return) of connector J3.
Varying the current source from 0 to 1mA will vary the current limit from 0 to 100%
of the model rating. The output voltage is set by adjusting the front panel voltage
control.

Programming Output Current Limit with a 0-5k Resistance
1. Remove the jumpers connecting pins 10 to 11 and pins 22 to 23 on connector J3.
2. Connect pins 10 (current limit programming input/positive) and 22 (1mA
current source for current control) to the counterclockwise end of the 5k
potentiometer and connect the tap and clockwise end of the potentiometer to pin
12 (return).
Adjusting the resistance from 0 to 5k will vary the current limit from 0 to 100% of
the model rating. The output voltage is set by adjusting the front panel voltage
control.
