5.  Increase the  VOLTAGE setting until the Voltage LED display 

reads the desired value. The  FINE control permits easier setting 
to a specific value. 

6.  Note the load current on the Current LED display. 
7.  If the load current exceeds the preset current limit, the  CV 

indicator will go off and the CC indicator will light. In this case, 
the power supply automatically switches to the constant current 
mode, and further rotation of the  VOLTAGE  control will not 
increase the output voltage. 

 
SETTING CURRENT LIMIT 
 

1. Determine the maximum safe current for the device to be 

powered. 

2. Temporarily short the (+) and (-) terminals of the power 

supply together with a test lead. 

3. Rotate the  Coarse VOLTAGE  control away from zero 

sufficiently for the CC indicator to light. 

4. Adjust the Coarse and  Fine CURRENT  control for the desired 

current limit. Read the current value on the Current LED 
display. 

5. The current limit (overload protection) has now been preset. Do 

not change the CURRENT  controls settings after this step. 

6. Remove the short between the (+) and (-) terminals and hook 

up for constant voltage operation.
