Светодиодный 0 28 дюймовый микро цифровой дисплей постоянного тока Регулируемый

LED 0.28 inch micro digital DC number display adjustable module

The voltmeter is small and the range is DC 0-100V. 2-wire and 3-wire products are versatile. Break the limits of conventional voltmeters. It is the latest design and can work directly in 5V, 9V, 12V, 24V and other circuits without voltage regulation. Equipped with three wirings, 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 voltage range is 0-100V, which can also be used as a second-line but the voltage should be within 40V.
