1.Use as a step-down modules with overcurrent protection capabilities  Usage:
(1) adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
(2) use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined overcurrent protection value. (For example, the meter displays the current value of 4A, then you can use the module to a maximum current of 4A)
(3) Connected to the load.
