Voltmeter Digital Mini DC 0-100V 0.28 inch – Biru

This voltmeter has a DC range of DC0-100V . It is common for 2- wire 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 connect to the lines in the car / battery car / motorcycle. It has the reverse connection protection function. 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 danger of burning . Note: The voltage range of the 3-wire is 0-100V, and it can also be used as the 2-wire but the voltage should be within 40V technical parameter 2- wire working voltage: 4.0 ~ 40 V ( with reverse connection protection function ) 2- wire detection voltage: 0.0 ~ 4 0V 3- wire working voltage: 4.0 ~ 40 V ( with reverse connection protection function ) 3- wire detection voltage: 0.0 ~ 100V Operating Current: < 2 0mA Display: of 0.
