Applications:

1. Constant current working mode (CC): The load always consumes a constant current regardless of how the input voltage changes.

Applicable scenarios:

? Load modulation test of power supply

? Battery discharge time and life test

? Battery consumption test

? Simulated on-load current of windshield wiper

2. Constant voltage working mode (CV): The load will consume enough current to keep the load input voltage constant at the set value.

Applicable scenarios:

? Mobile phone charging test

? Current limit test for foldback function of power supply

? Battery consumption test

? Current source test

3. Constant resistance working mode (CR): The load is equivalent to a constant resistance, and the load input current will be adjusted with the change of the load input voltage

Applicable scenarios:

? Slow startup test of communication power supply

? Driver test of light emitting diodes (LEDs)

? Simulated load condition of car temperature controller

4. Constant power working mode (CP): The load will consume a constant power, and the load input current will be linearly adjusted with the change of the load input voltage to ensure that the power consumption remains unchanged.

Applicable scenarios:

? Constant power supply test

? Battery capacity and life test
