Product Details


This module is different from the market LM2596, XL4005 buck module,They use chips Design power, respectively 15W, 50W, buck shop this module uses the chip upgrade, the input and output voltage range, output power, efficiency than similar products, power To be 75W, with a very high price.

Module Highlights:

  1. 5A High Power High efficiency step-down Low ripple!
  2. With power indicator light!
  3. Onboard voltage meter, voltage meter can self-calibration, will never exist without accurate voltmeter problem! !
  4. With heat sink!
  5. Get pillars! ! !



Module performance and features:


  • With power indicator light
  • With a voltage meter and voltmeter can display self-calibration. It uses a more advanced microprocessor voltage, voltage meter error 0.05V , Range 0 ~ 40V . Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage 4.5V the above
  • Touch the button to switch measuring input or output voltage, and has a light show which is being measured voltages, and save the settings, even if the power is turned on again.
  • Voltmeter can be turned off when not needed, touch the left button can be easily achieved.
  • Band terminals, no iron can also be easy to use, and retention wire connection points.
  • Input voltage 4.0 ~ 38V . ( Input voltage must be higher than the output voltage 1.5v the above )
  • Adjustable output voltage range 1.25V ~ 36V Continuously adjustable. ( Input voltage must be higher than the output voltage 1.5V)
  • Output current Up 5A Recommended 4.5A Internal use.
  • Output Power Up 75W .
  • High conversion efficiency, Up 96% Efficiency and input and output voltage, current, pressure related
  • Load Regulation S I 0.8% , Voltage regulation S u 0.8%
  • Overheating protection and short circuit protection
  • size 66 * 39 * 18mm
  • Weight 33 g



Onboard voltage meter self-calibration method:

1. When the board voltmeter shows the output voltage, long press on the right button 2 Seconds after the release, voltmeter and an output voltage indicator OUT Synchronous flashing, this time into the output voltage adjustment mode; Similarly, when the input voltage voltmeter display, press the button on the right side 2 Seconds after the release, voltmeter and input voltage indicator IN Synchronous flashing, this time into the input voltage adjustment mode;

2. Touch the button on the right side, the voltage increases a unit, touch the button on the left side, a voltage reduction unit; since the voltage value of less than one unit 0.1V , So you need to continuously press 1-5 Times to see changes in the voltmeter 0.1V Specific continuous button several times depending on the voltage value currently displayed, the current display higher the voltage, the less the number of press;

3. After the voltage is adjusted, press the button on the right side 2 Seconds after the release, this time to exit calibration mode voltage, All parameters set to automatically power-down save .

NOTE: You only need to adjust the way this one can obtain accurate calibration voltage value across the entire voltage range, this function is more accurate to meet your requirements and design, ease of use.




This module can be applied in the field of blood pressure is higher than the output voltage of the input voltage, such as batteries, power transformers, DIY Adjustable power supply, 24V Car T of this power, industrial equipment buck, 12V turn 3.3V , 12V turn 5V , 24V turn 5V , 24V turn 12V , 36V turn 24V Wait.
