5A Li-lion Lithium Battery Charger Module Step Down Buck Converter Constant Current Voltage LED Driver 5V-32V to 0.8V-30V

★ This module is an adjustable buck module, the output voltage can be changed by adjusting the blue adjustable resistor on top of the module. The input and output voltage difference is 1V and a small output voltage of 0.8V is possible.

★ The IN-(input negative), IN+(input positive), OUT-(output negative), OUT+(output positive) marked on the module must be connected correctly, otherwise the module may be damaged.

★ Taken battery charge method of use:

 

1. Make sure you need to recharge battery float charging voltage and charging current, input voltage module;

2. Adjust the constant-voltage potentiometer, the output voltage regulation to around 5 v.

3. The output short circuit current is measured with a multimeter 10 a current block, and regulate the flow of constant potentiometer output current reaches a predetermined charging current value;

4. The lamp current charging the default delivery is 0.1 times the charging current (constant current value). 

5. Adjust the constant-voltage potentiometer to output voltage float charging voltage;

6. Battery is connected, try to charge.

(1, 2, 3, 4, 5 steps for input power management module, the output light batteries!)

 

★ Taken the LED constant current drive method of use:

 

1. Make sure you need to drive the LED working current and maximum working voltage;

2. Adjust the constant-voltage potentiometer, the output voltage regulation to around 5 v.

3. The output short circuit current is measured with a multimeter 10 A current block, and regulate the flow of constant potentiometer output current to the expected LED working current;

4. Adjust the constant-voltage potentiometer to make the output voltage LED highest working voltage;

5. Plug in the LED, commissioning.
