1 Composition: The buck converter consists of 36u thickened circuit board, high Q inductor with output LED indicator, and solids state capacitor that can effectively filter high frequency noise. Suitable for all kinds of electronic projects 2 Use Method: Connect to the power supply, use mini screwdriver to increase or decrease the output voltage by adjusting the screws on blue potentiometer, and use multimeter display voltage to get the desired voltage, clockwise to increase the voltage, counterclockwise to buck 3 Simple Operation: The voltmeter can be turned off, press and hold the switch for more than 1s, and less than 4s to turn off the switch, once the voltmeter is off, just press the switch to turn on the voltmeter 4 High Efficiency: 150KHz internal oscillation frequency, low power consumption and high efficiency, when output voltage cannot be adjusted and always equal to input voltage, please turn potentiometer counterclockwise more than 10 times, then adjust the voltage normally 5 Basic Specifications: Input voltage is 4.0V - 40V, output voltage is 1.25V - 37V, output current is 2A (normal and stable) and 3A maximum
What's in the box
