0.36 inch DC 0-30V 3-Wire Digital Voltmeter Display Module - Green

This voltmeter has a volume of 0.36 inches , a range of DC 0-32V , and is common to 2 and 3 wire products. It breaks the conventional voltmeter and is the latest design. It can work directly in 5V , 9V , 12V , 24V and other circuits without the need for voltage regulation. Equipped with three wires , it is convenient to access the lines in the car / battery car / motorcycle. It has the function of reverse connection protection . The reverse connection will not burn. It is used to monitor the battery voltage, grasp the battery voltage status in time, and can also be used for voltage measurement of other products. Note that the maximum input voltage of the 2- wire cannot exceed 30V, otherwise there is a risk of burning .
