Product Description
DC Buck Step Down Voltage Regulator Module 6V-32V 30V 24V 12V to 1.5-32V 5V 5A Adjustable
Product parameters:
Input voltage: 6.5-36V (Input voltage is lower than 6.5V, current accuracy is not accurate, LCD display is abnormal when lower than 5.5V)
Output voltage: 1.2-32V, the factory default output is 5V. Step-down type, the output voltage can only be lower than the input voltage, the minimum voltage difference is 2V)
Output current: It can work stably at 3.5A for a long time, and it can reach about 4.5A with fan to strengthen heat dissipation (adjustable limit current is about 4.2-4.5A)
Output power: Natural heat dissipation 50W (within 3.5A), plus fan to enhance heat dissipation 75W
Voltage display: Resolution 0.05V, range 1.2-32V, approximate resolution accuracy is about ±0.1V (Be cautious for customers with demanding accuracy!)
Current display: Resolution 0.005A, range 0-4.5A, approximate resolution accuracy is about ±0.05A (Be cautious for customers with demanding accuracy!)
Conversion efficiency: About 94%, depending on pressure difference and current efficiency
Working current: About 30mA
Input reverse connection protection: Yes
Anti-backflow at the output: None (If charging the battery, power on the module before connecting the battery, and ensure that the battery voltage is lower than the output voltage; if possible, please connect an anti-backflow diode in series with the positive output)
Short circuit protection: Yes
Size: Length * width * height 70.5*48.4*28mm
Weight: 65g
Function Description:
There are IN/OUT and ON/OFF buttons on the left side of the module: IN/OUT button switches the display of input voltage and output voltage, long press can switch the display of output current and output power; ON/OFF button controls output ON or OFF, long Press to set the default output status of the next power-on to ON or OFF.
There are two buttons + and-on the right side of the module: + press the button once to increase the output voltage by 0.05V, long press to increase continuously, and long press to increase the output voltage by 0.1V, 1V in continuous slow steps;-press the button to decrease the output voltage by 0.05 V, long press to decrease continuously, and long press to decrease 0.1V, 1V continuously in slow steps.
ADJ-I is the current setting potentiometer. Rotate clockwise to increase the set current. When the load current reaches the set current, it enters the constant current state, and the CC constant current indicator (red) lights up. The OUT indicator is an output status indicator, which lights up when there is voltage at the output terminal, otherwise it is off; the CHAR indicator is a charging indicator, which lights up when charging, and the FULL indicator is a full indicator. If the set constant current value is 2A, charge When the current reaches below 0.2A, the lamp will turn on, the FULL indicator will be on, and the CHAR indicator will be off.
How to use:
1. Use as an ordinary step-down module with overcurrent protection capability
(1) Press the button to set the output voltage to reach the voltage value you want.
(2) First turn the ADJ-I current adjustment potentiometer counterclockwise to the end, then use a multimeter to measure the output short-circuit current at 10A current range (directly connect the two test leads to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise Make the output current reach the overcurrent protection value you want to set. (For example, the current value displayed by the multimeter is 2A, then the maximum current when you use the module can only reach 2A, when the current reaches 2A, the red constant current indicator light is on, otherwise the indicator light is off)
2. Use as a battery charger
The module without constant current function cannot be used to charge the battery. Because the voltage difference between the exhausted battery and the charger is very large, the charging current is too large and the battery is damaged. Therefore, the battery must be constant at the beginning. Current charging, when the charging reaches a certain level, it will automatically switch back to constant voltage charging.
(1) Determine the floating voltage and charging current of the rechargeable battery you need; (If the lithium battery parameter is 3.7V/2200mAh, then the floating voltage is 4.2V and the maximum charging current is 1C, which is 2200mA)
(2) Under no-load conditions, the button output voltage reaches the float voltage; (if charging a 3.7V lithium battery, adjust the output voltage to 4.2V)
(3) First turn the ADJ-I current adjustment potentiometer counterclockwise to the end, then use a multimeter to measure the output short-circuit current at the 10A current range (directly connect the two test leads to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise Make the output current reach the predetermined charging current value;
(4) Connect the battery and charge it.
(When setting steps 1, 2, and 3: the output terminal is not connected to the battery without load)
3. Use as a high-power LED constant current drive module
(1) Determine the operating current and maximum operating voltage you need to drive the LED;
(2) Under no-load conditions, press the button to set the output voltage to reach the highest LED operating voltage;
(3) First turn the ADJ-I current adjustment potentiometer counterclockwise to the end, then use a multimeter to measure the output short-circuit current at the 10A current range (directly connect the two test leads to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise Make the output current reach the predetermined LED working current;
(4) Connect the LED and test the machine.
(When setting steps 1, 2, and 3: output no-load without LED light.)
Package includes:
1 x DC Buck Module
Note:
1. Module input IN- must not be short-circuited with output OUT-, otherwise the constant current function will fail.
2. Please make sure that the power of the power supply is always greater than the power required by the output load. Please reduce the power when the module is seriously hot!
