Features:
This is a powerful DC-DC boost power supply module for electrical equipment, digital products, etc. You can use it to DIY a regulated power supply, input voltage is 3V-35V, the output voltage can be adjusted from 5V-45V. Monolithic integrated circuit, digital programming, precise control, reliable and durable.
0.9WH power inductor adopts brand new original IC input and output switching display, input and output terminals adopt screw terminal design to facilitate wire connection and disconnection. USB and 2.5A high current output design can identify resistance and simultaneously Telephone charging.
Module has inductor coil, copper heat sink, high precision potentiometer (clockwise boost, counterclockwise step down), digital tube voltage display (display voltage is more intuitive), input indicator and output indicator and other parts. More convenient to use, more comprehensive functions.
Power supply for your electronic equipment, you can set the output value according to your system voltage. DIY a high-power notebook mobile power supply with a large capacity 12V lithium battery, use your notebook as you like. DIY high current mobile power supply with a single-cell lithium battery. It comes with USB interface and identification resistor, and has a large current output of 2.5A, charge several mobile phones at the same time. Solar panel regulator power supply.
After inputting the power supply (3 - 35V), the input indicator lights up and the module works normally, adjust the blue potentiometer knob (usually rotate clockwise to increase the counterclockwise rotation and step down) and use the multimeter to detect the output voltage until it is needed. If the module output voltage cannot be adjusted, it is always equal to the input voltage.

Specifications:
Model: XH-M411
Input Voltage: 3V-35V
Output Voltage: 5V-45V
Input Current: 5A(Peak)
Voltage Display Range: 5V-30V(if input voltage is lower than 4.5V, it will not display)
Voltage Display Error: ±0.1V
Size: about 72*48*16mm / 2.83*1.89*0.63"

Notes:
This is a boost module so output voltage should be higher than input voltage.
Peak output current is less than 5A.
This kit requires professional knowledge and ability, please make sure you know how to use it.

Instructions:
1. Connect the module to power supply (4.5-40V), the input indicator light is on, and module is working normally.
2. Adjust the blue potentiometer knob (generally turn clockwise to step up and turn counterclockwise to step down) and check the output voltage with a multimeter until it meets requirement.
3. If the output voltage of the module can not be adjusted, which means it is always equal to the input voltage, please turn the potentiometer counter-clockwise for several circles then the voltage can be adjusted normally.

Package Included:
1 x XH-M411 DC-DC Boost Adjustable Step Up Converter 5V-45V Power Supply Module LED Voltmeter Digital Display.
Instructions are NOT included. We don't provide technical assistance please make sure that you are familiar with the product before purchasing.
