3.2.2 Constant Voltage Mode (CV)

In constant voltage mode, the DC load will cause a constant voltage to appear
at its terminals.
Input voltage

3.2.3 Constant Resistance Mode (CR)

In constant resistance mode, the DC load will behave as a fixed resistance
value.As shown below,the load linearly changes the current value with the
rising of input voltage.

3.2.4 Constant Power Mode (CW)

In constant power mode,the DC load will cause a constant power to be
dissipated in the load.As shown below,the load current is decreasing with the
rising of input voltage,while power always maintain the setting value.
