Operation
Remote Programming of Output Voltage and Current Limit
Revision A
59
Programming Output Voltage with a 0-5k Resistance
1. Remove the jumpers connecting pins 8 to 9 and pins 20 to 21 on connector J3.
2. Connect pins 9 (voltage programming input/positive) and 21 (1 mA current
source for voltage control) to the counter-clockwise end of the 5 k 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 output voltage from 0 to 100% of
the model rating. The output current limit is set locally by adjusting the front panel
current limit control.

Programming Output Current Limit with a 0-5Vdc Source
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 5Vdc 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.
