0.28 inch ultra small digital DC voltage meter digital display adjustable three-wire DC0-100V battery
voltmeter
This voltmeter range DC 0-100V, 2-wire and 3-wire products are common, breaking the conventional
voltmeter, is the latest design, can work directly in 5V, 9V, 12V, 24V and other circuits, no need for
voltage regulation. Equipped with three wires, it is easy to connect to the car/battery car/motorcycle car
line, with reverse connection protection function, the wire connection will not burn. It is used to monitor
the battery voltage, keep abreast of the battery voltage status, 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 three-wire use voltage range is 0-100V, which can also be used for two-wire but the voltage
should be within 40V.
