lm2596 cc cv adjustable dc to dc step down led driver charger battery

LM2596 DC-DC Step Down Adjustable CC/CV Power Transformer Supply Module Voltage Converter LED driver Charging Board
Features:

1.Fixed turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full);
2. Increased input reverse polarity protection diode;
3. Using dedicated reference IC, and high-precision sampling resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%).

Particularly suitable for LED driver

Battery use:

* Make sure of the voltage and current of the battery you need to charge
* Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
* Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease)
*Use the multimeter in 10A current scale to measure output short-circuit current,
and adjust the current potentiometer to make sure the output current to the expected charging current value
* The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
* Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power sour
