Operating Mode Description
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 When CC+CV mode is enabled, the unit will act
as constant current load after the input voltage
is greater than the user-defined CV level. At the
CV level, the unit works as a constant voltage
load. This mode effectively creates a voltage
ceiling before the unit operates in CC mode.
The diagram below illustrates this.
