XH-M411 DC-DC Step Up Module

The XH-M411 is a DC-DC step-up (boost) converter module used to increase a lower input voltage to a higher, regulated output voltage. It is a versatile module often used in DIY electronics projects, for powering devices, and with solar panels.

Specifications:

• Model: XH-M411
• Input Voltage: DC 3V to 35V
• Output Voltage: DC 5V to 45V, adjustable via a potentiometer.
• Input Current: 5A (peak).
• Output Current: Peak output is less than 5A, with a maximum of 2.5A from the USB port.
• Voltage Display: A built-in digital voltmeter displays the voltage, with a range of 5V to 30V. The display is not active if the input voltage is below 4.5V.
• Dimensions: Approximately 72 x 48 x 16mm.

Features:

• Adjustable Output: A blue potentiometer knob allows for manual adjustment of the output voltage. Turning it clockwise increases the voltage, while counter-clockwise decreases it.
• Digital Voltmeter: The module has a digital display to provide a more intuitive and accurate reading of the voltage. A button allows you to switch between viewing the input and output voltages.
• USB Port: It includes a USB output with a large current capacity (up to 2.5A), making it capable of charging multiple mobile devices simultaneously.
• Convenient Terminals: The input and output connections are made with screw terminals, which are easy to use for wire connections.
• Heat Dissipation: A built-in heat sink ensures proper heat dissipation during operation.

Applications:

• DIY Regulated Power Supply: Use it to create a stable, adjustable power source for various electronic projects.
• Mobile Power Bank: Combine it with a high-capacity lithium battery to create a portable power bank for laptops and other devices.
• Solar Panel Regulator: It can regulate the output voltage from a solar panel to charge batteries or power other electronics.
• General-purpose Power Supply: Power up a wide range of electrical equipment and digital products that require a higher voltage than your input source. 

Important Notes:

• Boost Function Only: As a boost module, the output voltage must always be greater than the input voltage.
• Troubleshooting: If the output voltage cannot be adjusted and remains equal to the input, turn the potentiometer knob counter-clockwise for several turns. This can re-engage the variable resistance functionality.
• Professional Knowledge: The manufacturer recommends that users have professional knowledge of electronics to safely and effectively use this module.
