โมดูลแปลงไฟ Step down จาก 4-38V เป็น 1.25-35V กระแสสูงสุด 5A XL4015 constant voltage buck module voltage and current display

Reminder:  Some customers report that the output voltage of the module cannot be adjusted and is always equal to the input voltage. When you encounter this kind of problem, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally. Because this step-down module leaves the factory, the default output voltage is about 20V.

Module Highlights:

5A high-power, high-efficiency buck and low ripple!
With power indicator light!
On-board voltmeter, the voltmeter can be self-calibrated, there will never be the problem of inaccuracy of the voltmeter! !
With heatsinks!
Free Bronze Pillar!

Module performance and features:

● With power indicator

● With voltmeter display and the voltmeter can be self-calibrated. Using a more advanced voltage microprocessor, the error of the voltmeter is ±0.05V , and the range is 0~40V . (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V )

● Tap the button to switch the measurement input or output voltage, and there is an indicator light to show which voltage is being measured, and save the settings, even if the power is turned off and then turned on again.

● The voltmeter can be turned off, and it can be easily achieved by pressing the left button when not needed.

● With terminals, it is easy to use without a soldering iron, and the connection points of the soldering wires are reserved.

● Input voltage 4.0 ~ 38V . ( The input voltage must be more than 1.5v higher than the output voltage )

● The adjustable output voltage range is 1.25V ~ 35V continuously adjustable. ( The input voltage must be 1.5V higher than the output voltage)

● The output current can reach 5A , it is recommended to use within 4.5A .

● The output power can reach 75W .

● High conversion efficiency, up to 96% (efficiency is related to input, output voltage, current, and voltage difference)

● Load regulation rate S ( I ) ≤ 0.8% , voltage regulation rate S ( u ) ≤ 0.8%

● With overheat protection and short circuit protection

● Size  6 0 *3 7 *18mm

● Weight  28 g

 
On-board voltmeter self-calibration method:

1. When the on-board voltmeter displays the output voltage, press and hold the right button for 2 seconds and then release, the voltmeter and the output voltage indicator " OUT " flash simultaneously, and enter the output voltage adjustment mode; When inputting voltage, press and hold the right button for 2 seconds and then release, the voltmeter and the input voltage indicator " IN " flash simultaneously, and enter the input voltage adjustment mode at this time;

2. Touch the right button to increase the voltage by one unit, and touch the left button to decrease the voltage by one unit; since the voltage value of one unit is less than 0.1V , you need to press 1-5 times continuously to see the voltmeter Changed by 0.1V , the specific number of consecutive keys depends on the currently displayed voltage value, the higher the current displayed voltage, the less the number of times of pressing;

3. After the voltage adjustment is completed, press and hold the right button for 2 seconds and release it, then you can exit the voltage calibration mode, and all parameter settings are automatically saved after power off.

Note: In this adjustment method, you only need to calibrate once to get the accurate voltage value on the entire voltage range. This function is designed to meet your higher accuracy requirements, please use it with confidence.

Application range:

    This module can be used in the step-down field where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supplies, 24V car notebook power supplies, industrial equipment step-down, 12V to 3.3V , 12V to 5V , 24V to 5V , 24V to 12V , 36V to 24V , etc.
