DC-DC Buck Converter Module Constant Current Voltage Regulator Step Down Converter Charging Board DC 5V-32V


Specification:

Input voltage range: 5~32VDC (Note: the input voltage does not exceed 32V)

Output voltage range: 0.8-30VDC adjustable

Output current: 0-5A (adjustable)

High efficiency: up to 95%

Input reverse polarity protection: None (if necessary, a high-current diode in series with the input).


Feature:

Built-in thermal shutdown function, current limiting function, output short circuit protection function.

Fine workmanship and good performance.

high efficiency.

Easy to use.

long lasting.


As a battery charger


Modules without constant current function cannot be used to charge the battery, because the charger puts a lot of pressure on the complete consumption of the battery, causing the charging current to be too large and causing damage to the battery. Therefore, when the battery starts to use constant current charging, the battery will be charged to a certain level. Automatically switch back to constant voltage charging.


Usage:

1. Determine the float voltage and charging current of the battery that needs to be charged.

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

3. Use a multimeter (10A) to measure the short-circuit current and adjust the constant current potentiometer to make the output current reach the predetermined charging current value.

4. The charging current defaults to 0.1 times of the charging current (constant current value).

5. Adjust the output voltage of the constant voltage potentiometer to a floating voltage.

6. Battery, try charging.

(Steps 1, 2, 3, 4, and 5 provide power for the input of the module, and the output is no-load and non-battery.)


Used as an ordinary step-down module with overcurrent protection function

1. Determine the operating current that needs to drive the LED.

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

3. Use a multimeter (10A) ammeter to measure the short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current.

4. Constant voltage potentiometer makes the output voltage reach LED. High working voltage.

5. LED testing machine.

(Steps 1, 2, 3, and 4 provide power for the module input, and no LED lights on the output.)

This module is greater than 5A when in use to enhance heat dissipation.

Package Included:

1 x DC buck converter


Notes:

When using this module, the input GND and output GND cannot be combined.

The IN (input negative), IN+ (input positive), OUT- (output negative), and OUT+ (output positive) on the top of the module must be correct, otherwise the module may damage the module.
