XL4015 5A Step Down Adjustable Power Supply with LED Voltmeter
The XL4015 5A Step Down Adjustable Power Supply with LED Voltmeter module is a DC/DC module that converts a higher input voltage to a lower output voltage with high efficiency, low ripple, and excellent line and load regulation. It uses a 180 kHz fixed frequency PWM buck (step-down) method. The module has a voltmeter display that shows the input and output voltages. It can also be calibrated for accuracy.
The voltmeter can switch between input and output voltage measurements, with an indicator light. The voltmeter can also be turned off. The board has connection terminals for easy wiring.
The DC/DC buck module is suitable for applications that require a lower output voltage than the input voltage, such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TV portable instrument power supply, telecom/networking equipment, 24V vehicle notebook power supply, industrial equipment buck.
This module can adjust the output voltage and current. It can also act as a dedicated charger for lithium batteries (Li-Ion, LiPo) as it can control both voltage and current. For example, it can convert 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
Voltmeter calibration method :
- Onboard voltmeter shows that the output voltage, long press the right button 2 seconds to loosen, voltmeter, and the output voltage indicator light [OUT] synchronous flash, at this time into the output voltage regulation mode; Similarly, when the input voltage IN the voltmeter display, long press the right button 2 seconds to loosen, voltmeter, and the input voltage indicator light [IN] synchronous flash, at this time into the input voltage adjustment mode.
- Light touch button on the right side, the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit of voltage is less than 0.1 V, so you need to press the 1-5 consecutive can see the voltmeter change 0.1 V, the concrete continuous button several times depends on the current display voltage, current shows that the higher the voltage, the fewer the number of press.
- After the voltage adjustment, long press the right button for 2 seconds, release, to exit the output voltage calibration mode, all the parameters set to automatically power down saving.

Applications & Use Cases
The XL4015 5A Step Down Adjustable Power Supply with LED Voltmeter is a versatile buck converter used across a wide range of applications including voltage step-down for electronics, battery-powered projects, LED driver circuits, microcontroller power supply, and solar power regulation.
Common use cases:
- Converting 12V car battery to 5V for USB devices
- Powering a Raspberry Pi from a drone battery
- Regulating solar panel output for charging
This product is ideal for electronics hobbyists, IoT developers, and power supply designers.
Technical Tip: Buck converters are more efficient than linear regulators (LM7805). Choose one rated for at least 1.5x your required current. Ensure input voltage is at least 2V above output.
