Product description:

Input voltage range: DC 3.2V to 40V (input voltage must be 1.5V higher than output voltage).

Output voltage range: DC 1.25V to 35V continuously adjustable voltage, maximum output current is 3A.

Steps to use: Turn on the power (3-40V), the power indicator light, the module is working normally, adjust the blue potentiometer knob (usually turn clockwise to raise the voltage, counterclockwise to lower it), use a multimeter to monitor the output voltage until it reaches the required voltage. The module can be used to debug various systems working voltage range.

Applications: Widely used in DIY mobile power supply, monitoring power supply, electric car, communication equipment power supply and so on.

Package includes:6pcs DC buck variable voltage regulators
