Large current 5A constant voltage voltage voltage voltage voltage voltage voltage low -voltage power supply module LED drives lithium battery charging

When using this product, do not share the input and output of the module. This will cause the current sampling resistor on the back of the board to be bypass, so that the module cannot adjust the output current.Burning the power chip on the module.

This module is simple and easy to use and powerful!IntersectionIntersection

Two two, application range

1. As a normal antihypertension module with overcurrent protection capabilities

How to use:

(1) Regulate the constant voltage potentiometer so that the output voltage can reach the voltage value you want

(2) Use a multimeter 10A current gear to measure the short -circuit current (the two tablets can be directly received to the output terminal), and at the same time, the constant current potentiometer makes the output current reaches the predetermined overcurrent protection value.(For example, the current value displayed by the multimeter is 4A, so when you use the module, the maximum current can only reach 4A. When the current reaches 4A, the red constant voltage constant current indicator is on, otherwise the indicator light will be extinguished))

Note: When using in this state, due to the current sampling resistor of 0.05 Euros of 0.05 Euros, there will be a voltage drop of 0 ~ 0.3V after the load is connected. This is a normal phenomenon!This pressure drop is not lowered by your load, but to the sampling resistance.

2. Use as a battery charger

The module without constant current function cannot be used to charge the battery. Because the battery consumed by the battery and the charger is very large, the charging current is too large and the battery is damaged.Flow charging, automatically switch back to constant voltage charging when charging to a certain degree.

How to use:

(1) Determine the floating charging voltage and charging current of the battery; (if the lithium battery parameters are 3.7V/2200mAh, then the floating charging voltage is 4.2V, the maximum charging current is 1C, that is, 2200mA)
(2) Under the air load conditions, the universal meter measuring the output voltage, adjust the constant voltage potentiometer to achieve the output voltage to the floating charging voltage; (if the 3.7V lithium battery is charged, the output voltage can be adjusted to 4.2V)
(3) Use a multimeter 10A current file to measure the output short -circuit current (just receive the two tablets to the output terminal), and adjust the constant current potentiometer to achieve the output current to reach the predetermined charging current value;
(4) The current charging rotor current is 0.1 times the charging current; (the current of the battery is gradually reduced during the charging process, and the constant current charging to constant voltage charging is gradually changed.When the charging current is less than 0.1A, the blue light is destroyed and the green light is on. At this time, the battery is charged)
(5) Connect the battery and charge.

(Step 1, 2, 3, 4 are: input terminal connection power, the output end is empty and does not connect the battery)

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

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

(2) Under the air load conditions, the universal meter measuring the output voltage, adjust the constant voltage potentiometer to make the output voltage reaches the highest working voltage of LED;

(3) Use a multimeter 10A current file to measure the output short -circuit current, and adjust the Hengli potentiometer to make the output current reaches the predetermined LED working current;

(4) Connect the LED, test machine.

(Step 1, 2, 3 are: input the power supply, the output is not connected to the LED light.)

Note: When this module is used more than 3A and 35W, please strengthen the heat dissipation!IntersectionIntersection
