13.This module can change the output voltage by adjusting the blue adjustable resistor on top of the module. The input and output voltage difference is 1V, which can output a voltage of 0.8V.
Usage of LED constant current drive:
1. Determine the working current and high working voltage that you need to drive the LED;
2. Adjust the constant voltage potentiometer to adjust the output voltage to around 5V.
3. Use a multimeter to measure the output short-circuit current in the 10A current range, and adjust the constant current potentiometer to adjust the output current to the predetermined LED working current;
4. Adjust the constant voltage potentiometer to increase the operating voltage of the output voltage LED;
5. Connect the LED and test the machine.

Application range:
Charging for lithium-ion batteries: when the lithium ion battery when the voltage is low, if the direct use of constant voltage charging, due to pressure, leading to the charging current is too large, resulting in damage to the battery, so from the beginning to use the constant current charging the battery when charging, to a certain degree of automatic switch back to the constant voltage charging.
