915 Generation 0.36 Inch DC 2.5-40V 3 Digit Voltage Panel Meter LED Color B

The volume of this voltmeter is 0.36 inches, the range is DC 0-40V, 2-wire access, breaking the conventional voltmeter, is the latest design, can directly work in 5V, 9V, 12V, 24V and other circuits, without voltage regulator.
Equipped with two wires, It is convenient to connect to inside the car/battery car/motorcycle. It has the function of reverse connection protection, and will not burn if it is reversed.
It is used to monitor the battery voltage, grasp the battery voltage status in time, and can also be used for other product voltage measurement purposes.
Note that the maximum input voltage for 2-wire use cannot 40V, otherwise there is a risk of burning.
Note: The operating voltage should be within 40V (many peers can only be within 30V, and the of 30V is also lower). Ultra-low startup voltage, 3.0V. If conditions permit, it is recommended to use the best voltage range DC 4V-30V.
Good product stability and high measurement accuracy.
Appearance adopts standard size, easy to install.
The power supply adopts polarity protection circuit.
