Main highlights- Solderable Power Cord: The soldering wire connection point is retained on the board, so you can choose whether to solder the power cord according to your needs; If not necessary, you can also connect the power cord to the terminal block
- Practical DC-DC Buck Converter: Step down power converter can lower the voltage. Input voltage range 4.0-40V, output voltage range 1.25-37V; output current 2A, output power 15W, operating frequency: 150KHZ. If the output voltage does not match the electrical equipment, you can manually adjust the output voltage
- Note: When the output voltage cannot be adjusted and is always equal to the input voltage, please turn the potentiometer counterclockwise for more than 10 turns before you can use the module normally. This is because the default output voltage is 20V when it leaves the factory
- LED Display: Buck converter has the function of displaying voltage and can accurately measure the voltage value. If you need to switch the display of input or output voltage, just press the button on the right; if you want to turn off the digital display, please press the button on the left
- How to Use: Connect the power adapter to the input terminal of the buck converter and check the output voltage. If the output voltage does not match the electrical equipment, use a screwdriver to twist the potentiometer. Clockwise rotation increases the voltage, counterclockwise rotation decreases the voltage. After confirming that the output voltage is OK, connect the electrical device to the output terminal
