    4. How to use
    4.1. Use as an ordinary buck module with overcurrent protection capability
    (1) Press the key to set the output voltage to your desired voltage.
    (2) Turn the ADJ-I current adjustment potentiometer counterclockwise first, then measure the output short-circuit current with the multimeter 10A current range (directly connect the two test leads to the output), and adjust the ADJ-I constant current potentiometer clockwise to make the output The current reaches the overcurrent protection value you want to set. (For example, the current value displayed by the multimeter is 2A, then when you use the module, the maximum current can only reach 2A. When the current reaches 2A, the red constant current indicator is on, otherwise the indicator is off)
    4.2. Use as a Battery Charger
    A module without a constant current function cannot be used to charge the battery. Due to the large voltage difference between the battery and the charger when the battery is exhausted, the charging current is too large and the battery is damaged. So when you start, you need to charge the battery with a constant current, and when it is charged to a certain degree, it automatically switches back to constant voltage charging.
    (1)Make sure you need the float charge voltage and charge current of the rechargeable battery; (if the lithium battery parameter is 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charge current is 1C, ie 2200mA)
    (2) Under no-load conditions, press the button to adjust the output voltage to reach the float voltage; (If charging the 3.7V lithium battery, adjust the output voltage to 4.2V)
    (3) Turn the ADJ-I current adjustment potentiometer counterclockwise first, then measure the output short circuit current with the multimeter's 10A current range (directly connect the two test leads to the output terminal) and adjust the ADJ-I constant current potentiometer clockwise. Make the output current reach the predetermined charging current value;
    (4) Connect the battery and charge it.
    (When setting steps 1, 2, and 3: The output terminal is empty and no battery is connected)
    4.3. Use as a High Power LED Constant Current Drive Module
    (1) Make sure that you need to drive the LED's operating current and maximum operating voltage;
    (2) Under no-load conditions, press the key to set the output voltage to the maximum LED operating voltage;
    (3) Turn the ADJ-I current adjustment potentiometer counterclockwise first, then measure the output short circuit current with the multimeter's 10A current range (directly connect the two test leads to the output terminal) and adjust the ADJ-I constant current potentiometer clockwise. Make the output current reach the predetermined LED operating current;
    (4) Connect the LED, test machine.
    (When setting steps 1, 2, and 3: Output no-load LED light.)
    5. Note
    5.1. The module input 'IN-' must not be shorted to the output 'OUT-', otherwise the constant current function will fail.
    5.2. Please ensure that the power supply power is greater than the power required by the output load. When the module is hot, reduce the power usage!
    5.3. Please read the product description carefully before use. Any damage caused by improper use will not be compensated.
    12A step-down module
    12A step-down power supply module (constant voltage constant current LCD display, with crystal shell)
    note! ! ! Module default output voltage and current is about 18V / 7A, because the module is a step-down module, you need to reduce the output voltage below the input voltage will work, if you receive the module and found that the output voltage can not be adjusted, Clockwise rotation CV voltage regulator potentiometer 20 laps or more, and then use the module to regulate the voltage; the module for the DC to DC buck module, can not enter the AC, such as transformers; The above problems we do not assume the responsibility and shipping costs, thank you Understanding.
    Module default output 18V / 7A or so, the direct short-circuit output current regulation, will have a greater spark prone to danger, it is recommended short output before the first output voltage down to 10V below, CC current potentiometer counter-clockwise Rotate more than 10 turns to the end, and then short the output, turn the CC current adjustment potentiometer clockwise to slowly increase the current value you need.
