Advanced Operation Sorensen DCS Series 3kW Supplies
WARNING
Exercise caution when resetting internal jumpers. Review Section 2.2 Safety and
follow procedures for removing the cover and resetting jumpers in Section 4.2.3.
Programming Output Current Limit with a 0-1 mA 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 1 mA will vary the output voltage from 0 to 100% of the
model rating. Adjusting the front panel voltage control sets the output voltage.
Figure 4-10 Programming Output Current Limit with a 0-1 mA Source
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 (1 mA 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. Adjusting the front panel voltage control sets the output voltage.
