DC-DC Step Down XL4015 (Peak 5A) w/ Display & USB, Adjustable Voltage & Current, Regulator Module Buck Converter

  • RM30.00

  • Product Code: XL4015 w/ Display & USB
  • Availability: In Stock

With this XL4015 module, you can monitor your project much more easier. The voltage meter can measure the input voltage or output voltage, which is adjustable by the protentiometer, with a precision of ±0.1V. Note that the voltage meter would not work if the input voltage below 4V. Press the button (right) to switch voltage to measure, between the input voltage and output voltage. There are 2 LEDs to indicate which voltage is measuring by the voltage meter. And it has a Power indicator LED (GREEN). You can change the input or output voltage measurement by Short press the button on the right side ,and also can close the voltage meter by pressing the button on the left side.



  • Module Properties: non-isolated step-down (BUCK) switching regulator
  • Input voltage: DC 5.0 - 36V
  • Output Voltage: Adjustable 1.25 - 32V DC (Input must 1.5V greater than output)
  • Output Current: Rated 4A, max. 5A (Heat sink required)
  • Measurement Accuracy: ±0.1V (To ensure the accuracy, keep the input above 4.5V)
  • Conversion efficiency: Up to 96% (Output voltage higher, the higher the efficiency)
  • Minimum dropdown voltage:1.5V
  • Voltage regulation: 0.8%
  • Short circuit protection: Yes (limit current 8A)
  • Switching Frequency: 180KHz
  • Circuit protection: Yes
  • Operating temperature: Industrial grade (-40 to +85°C)
  • Size: 68.2mm x 38.8 mm x 14mm



*Note: Gently rotate the potentiometer counter-clockwise around 7-8 round will drop the output voltage for the first time usage .


How to set-up:

  1. Power up the module with a stable and accurate power supply , such as a 5V power supply, then shot press the button on the right side to select which one do you need to adjust (input or output), and long pressing (press time > 2S) the button(right) makes the module enter the calibration model, after releasing the button, the related LED would blink to indicate which voltage is now calibrating, and the numeric display blinks the correction value.
  2. Short press the button to change the correction value, Short press the button on the right side, voltage increases one unit, Short press the button on the left side, voltage reduce one unit, for example, if your power supply is 5V, but the result of voltage meter is 4.8, you need to set the value to 5V.
  3. Long press button on the right side(press time ≈ 2S), to store the voltage correction value.
  4. Calibrate the output voltage in the same way above; The correction value will be stored in nonvolatile memory.
