7-5-4.  CV Mode 

CV Mode 

When the unit is set to CV mode it will operate as a constant 
voltage operation when connected to a constant current 
source. 
This means the unit will maintain the CV setting value, up to 
the rated power, regardless of the input current. 
This is illustrated below. 

 

 

 

Note that when the load voltage is less than the +CV setting 
value, no current will flow due to very high impedance.
