7-5-4. CV Mode

CV Mode

When the unit is set to CV mode it will operate
as a constant voltage load when connected to a
constant current source. This means the unit will
maintain a set voltage level, up to the rated
power, regardless of the input current. When the
source voltage is less than the CV level, no
current will flow due to a very high impedance.
This is illustrated below.
