7-5. Operating Mode Description
7-5-1. CC Mode
CC Mode When the unit is set to CC mode it will operate as a constant
current load when connected to a constant voltage source.
This means the unit will sink a designated amount of current,
up to the rated power level, regardless of the voltage.
This is illustrated below.
CC+CV Mode The unit will act as constant current operation after the load
voltage is greater than the +CV setting value. At the +CV
setting value, the unit works as a constant voltage operation.
This mode effectively creates a voltage ceiling before the unit
operates in CC mode.
The diagram below illustrates this.
Note that when the load voltage is less than the +CV setting
value, no current will flow due to very high impedance.
