Note that when the source voltage is less than
the CV level, no current will flow due to a very
high impedance.

CR Mode

CR Mode

When the unit is set to CR mode it will operate
as a constant resistance load when connected to
a constant voltage source. This means the unit
will maintain a set resistance, up to the rated
power, regardless of the input voltage. When
input voltage changes, the unit responds by
changing the current load to maintain the set
resistance according to ohm’s law. This is
illustrated below.
