Operating Manual for XKW 1kW Series Power Supply

Programming

With an

External

Resistance

The output voltage and current limit can be programmed using a 5k ohm external 
potentiometer.

To program the 

output voltage

, set switch SW1-3 open (default factory setting) and 

remove the jumpers connecting pins 8 to 9 and 20 to 21 on connector J3. Connect pins 9 
and 21 to the counterclockwise end of the 5k potentiometer and connect the tap and 
clockwise end of the potentiometer to pin 12. Adjusting the tapped resistance from 0-5k 
will vary the output voltage from 0-100% of the rated output.

Figure 3.10

(J3 sense line, OVP and current control jumpers shown set for local operation)

To program the 

output current limit

, set switches SW1-1 and SW1-2 open (default 

factory setting) and remove the jumpers connecting pins 10 to 11 and 22 to 23 on 
connector J3. Connect pins 10 and 22 to the counterclockwise end of the 5k 
potentiometer and connect the tap and clockwise end of the potentiometer to pin 12. 
Adjusting the tapped resistance from 0-5k will vary the current limit from 0-100% of the 
rated output.
