Buyers need to know that because they are linear, the efficiency will not be very high. To improve efficiency, it is best to have a voltage difference of 3V between the input and output. ≤30V, otherwise it is easy to burn the module.

Because it is a linear step-down DC-DC circuit, the input voltage needs to be more than 3V higher than the output voltage to ensure the stability of the output voltage.

Input voltage: 40V-4.5V (our store measured maximum limit can reach 40V),

Adjustment method: first connect the input power correctly (between 40-4.5), then use a multimeter to monitor the output voltage and adjust the potentiometer (generally clockwise to boost, counterclockwise to step down)

Tips: When adjusting the voltage, please pay attention to adjust the required voltage when no load is added
