【PHYTR】 Ultra Small Green Digital DC 0.28 Inch Ultra Small Digital DC Voltage Meter LED Voltage Display Adjustable Digital Display Three Wire DC0-100V Battery Voltmeter

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 battery 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 battery voltage and master the battery 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.New and high qualityModel: 0.28 inchWorking principle: electronic watt hour meterPower circuit: DC ammeterType of watt hour meter: reactive watt hour meterparameter2-wire working voltage: 4.0 40v (with reverse connection protection function)2-wire detection voltage: 0.0 40v3-wire working voltage: 4.0 40v (with reverse connection protection function)3-wire detection voltage: 0.0 100vWorking current: 20maDisplay mode: 0.28 led,Color: red yellow green bluePackage includes: 1pcNote:Please refer to the measurement.
