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.
