7-5-3. CP Mode
CP Mode When the unit is set to CP mode it will operate as a constant
power operation when connected to a constant voltage
source.
This means the unit will maintain a set CP setting value, up to
the rated current or voltage level, regardless of the load
voltage. When load voltage changes, the unit responds by
changing the current load to maintain the set power level
accordingly (P=IxV).
This is illustrated below.
CP+CV Mode The unit will act as a constant power 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 CP 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.
