Operating Instructions:
1. Connect the input terminal of XH-M411 to the power supply. The applicable power supply voltage is 4~35V. Pay attention to its positive and negative poles.
2. Turn on the power switch, and the XH-M411 screen will display the current boosted output voltage.
3. If the output voltage is not enough to meet the working voltage of the load, the voltage can be adjusted through the potentiometer.
4. Connect the output terminals to the load, paying attention to the positive and negative poles between them.
5. Press the voltage switch key to switch between output voltage and input voltage.

Package include:
2 x DC to DC boost converter module

Note:
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.

• DC-DC boost power supply module input voltage is 3V-35V, the output is 5V-45V
• Boost converter 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.
• 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
• DC boost converter for electrical equipment, digital products
• The DC-DC digital boost board has a voltage display function, which can display the input voltage or the output voltage, just press the button to switch
• the voltage it tests is very accurate, and it can also manually adjust the output voltage (5V-45V)
