Vôn kế điện tử 0.28 inch DC 0-100V 3 có đèn LED

Giới thiệu Vôn kế điện tử 0.28 inch DC 0-100V 3 có đèn LED

100% brand new and high quality.
Description:
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 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: The three-wire use voltage range is 0-100V, which can also be used for two-wire but the voltage should be within 40V.

Features:
1. Good product stability and high measurement accuracy
2. The appearance is standard size and easy to install
3. Power supply uses polarity protection circuit
