0-30 V Green Panel Voltmeter

Overview

This product is a small voltmeter that can be mounted by two screws. It has a very small error (1%) and has a resolution of 0.1 V. It has a maximum measured voltage of 30 V and is sufficient for most common applications.

This voltmeter is useful in building your own power source that consists of a power transformer and a power-down switching voltage.

The voltmeter has a volume of 0.36 inches and a range of DC DC0-100V. It is universal 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 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 wired 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 for two-wire but the voltage should be within 30V.
