Scope of application:

1. Use as an ordinary step-down module with over-current protection capability

Instructions:

(1) Adjust the constant voltage potentiometer to make the output voltage reach the voltage value you want

(2) Use a multimeter to measure the output short-circuit current with a 10A current file (directly connect the two test leads to the output terminal), and adjust the constant current potentiometer to make the output current reach the predetermined overcurrent protection value. (For example, the current value displayed by the multimeter is 4A, then the maximum current when you use the module can only reach 4A, when the current reaches 4A, the red constant voltage constant current indicator will be on, otherwise the indicator will be off)

Note: When used in this state, since the output terminal has a current sampling resistor of 0.05 ohm, there will be a voltage drop of 0~0.3V after the load is connected. This is a normal phenomenon! This voltage drop is not pulled down by your load, but dropped to the sampling resistor.

2. Use as a battery charger

The module without the constant current function cannot be used to charge the battery. Because the voltage difference between the exhausted battery and the charger is large, the charging current is too large and the battery is damaged. Therefore, the battery must be constant at the beginning. Current charging, when the charging reaches a certain level, it will automatically switch back to constant voltage charging.

Instructions:

(1) Determine the floating voltage and charging current of the rechargeable battery you need; (If the lithium battery parameter is 3.7V/2200mAh, then the floating voltage is 4.2V and the maximum charging current is 1C, which is 2200mA)

(2) Under no-load conditions, the multimeter measures the output voltage and adjusts the constant voltage potentiometer to make the output voltage reach the float voltage; (if charging a 3.7V lithium battery, adjust the output voltage to 4.2V)

(3) Use a multimeter to measure the output short-circuit current with a 10A current file (directly connect the two test leads to the output terminal), and adjust the constant current potentiometer to make the output current reach the predetermined charging current value;

(4) The default charging current of the rechargeable lamp is 0.1 times the charging current; (The current of the battery is gradually reduced during the charging process, and gradually changes from constant current charging to constant voltage charging. If the charging current is set to 1A, then when the charging current is set to 1A, When the charging current is less than 0.1A, the blue light is off and the green light is on, and the battery is fully charged at this time)

(5) Connect the battery and charge it.

(Steps 1, 2, 3, 4 are: the input terminal is connected to the power supply, and the output terminal is not connected to the battery without load)

3. Use as a high-power LED constant current drive module

(1) Determine the operating current and maximum operating voltage you need to drive the LED;

(2) Under no-load conditions, the multimeter measures the output voltage and adjusts the constant voltage potentiometer to make the output voltage reach the highest LED operating voltage;

(3) Use a multimeter to measure the output short-circuit current at 10A current level, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current;

(4) Connect the LED and test the machine.

(Steps 1, 2, and 3 are: the input is connected to the power supply, and the output is no-load without the LED light.)

Note: Please strengthen heat dissipation when this module is used over 3A and 35W! ! !
