  • Application 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
  • 2.Use as a battery charger Usage: (1). Make sure you need to charge the battery float voltage and charging
