instructions：

This module is an adjustable voltage reduction module that can change the output voltage by adjusting the voltage potentiometer. The input and output voltage difference is 2V. The IN - (input negative), IN+(input positive), OUT - (output negative), and OUT+(output positive) marked on the module must be connected correctly, otherwise it may cause damage to the module.

1. Battery charging usage method:

① Determine the float charging voltage and charging current of the rechargeable battery you need, as well as the input voltage of the module;

② Adjust the constant voltage potentiometer to adjust the output voltage to around 5V;

③ Measure the output short-circuit current with a multimeter in 10A current mode, and adjust the constant current potentiometer to achieve the predetermined charging current value

④ The default shipment of the charging to lamp power supply is 0.1 times the charging current (constant current value). If adjustment is needed, please adjust the lamp current potentiometer; (Usually does not require adjustment)

⑤ Adjust the constant voltage potentiometer to make the output voltage reach the float charging voltage;

⑥ Connect the battery and try charging.

(Steps 1, 2, 3, 4, and 5 are to connect the module input to the power supply and the output to no load without connecting the battery)

2. Usage of LED constant current driver:

① Determine the operating current and maximum operating voltage required to drive the LED;

② Adjust the constant voltage potentiometer to adjust the output voltage to around 5V.

③ Measure the output short-circuit current with a multimeter in 10A current mode, and adjust the constant current potentiometer to achieve the predetermined LED operating current;

④ Adjust the constant voltage potentiometer to make the output voltage reach the working voltage of the LED;

⑤ Connect the LED and test the machine.

(Steps 1, 2, 3, and 4 are to connect the module input to the power supply, and the output is unloaded without connecting the LED light)
