Description:
The range of this voltmeter is DC dc0-100v. 2-wire and 3-wire products are common. It breaks the conventional voltmeter and is the latest design. It can work directly in 5V 9V 12V 24V and other circuits without voltage stabilization.
Equipped with three wires it is convenient to connect to the lines in cars / cars / motorcycles. It has the function of reverse connection protection and the wires will not burn in reverse connection.
It is used to monitor the voltage and master the voltage status in time. It can also be used for voltage measurement of other products. Note that the maximum input voltage of line 2 cannot exceed 30V otherwise there is a risk of burning.
The voltage range of three wires is 0-100V and it can also be used as two wires but the voltage should be within 40V.
The product has good stability high measurement accuracy standard size for appearance convenient installation and polarity protection circuit for power supply.
