0.28\" 3Wire LED Minimun Digital Voltmeter DC0-100V Reverse Connection Protection

Features: *This voltmeter is small in size, with a range of DC0-100V. It is common for 2-wire and 3-wire products. It breaks the conventional voltmeter and is a new design. * Can work directly in 5V, 9V, 12V, 24V and other circuits without voltage regulation. * Equipped with three wires, it is convenient to connect to the line in the car/battery car/motorcycle. *It is used to monitor the battery voltage, grasp the battery voltage status in time, and can also be used for voltage measurement of other products. *Note that the 2-wire high input voltage cannot exceed 30V, otherwise there is a risk of burning. *The wiring is convenient and simple. It is equipped with three wires, which is convenient and simple in wiring, which is convenient to access the inner line of cars/battery cars/motorcycles. *Measurement accuracy, the voltage table will automatically move the position of the decimal point according to different measurement voltage. *This voltage meter can be used to measure the voltage of mobile phone lithium batteries, nickel -metal hydride battery packs and other battery packs, as well as voltage of batteries such as motorcycles and cars, and can also be used for other voltage meas urement purposes . Specification: 2-wire working voltage: 4.0~40V (with reverse connection protection function) 2-wire detection voltage: 0.0~40V 3-wire working voltage: 4.0~40V (with reverse connection protection function) 3-wire detection voltage: 0.0~100V Working current: Display mode: 0.28"LED, red green yellow ( optional) Dimensions: 30×11.7×9.2 mm (length Х width Х height) Mounting hole: 23×10mm Measuring rate: ≥200mS/time Measurement accuracy: 3‰ limited working conditions Low working voltage: +4.0V High working voltage: +40V Working temperature: -10～+65℃ Working humidity: 10-80% (no condensation) Working pressure: 80～106kPa Sunlight exposure: no direct exposure Package included: 1*voltage table Note: The voltage range of the three-wire is 0-100V, and it can also be used as the second-wire, but the voltage should be within 40V
