The device can be used in cars (12V or 24V) to obtain a stabilized output voltage for charging different devices - mobile phones, tablets, and more. After adjusting the required voltage. Adjustment is done via the multi-turn potentiometer. In order to keep the output voltage stable for consumption up to 3A current, the input voltage must be at least 1.5V above the output. The device can not increase - you can not get 12V from input 5V, but just the opposite. The output voltage setting is smooth and you can set any desired value between 0.8 - 34VDC.
