Description
3 Wire Red 3-bit 0-100V DC Digital Car Voltmeter Gauge LED Digital Tube Digital Display Voltage Meter Voltmeter
Features
The voltage meter is small and 0.36-inch with a shell, the range DC0-100V DC, the need for additional auxiliary power supply. Auxiliary power supply voltage range is wide, up to 4-30V, can work in 5V, 9V, 12V, 24V, etc., no regulator. Equipped with three wiring, easy access to the car / battery car / motorcycle car lines, with reverse protection function, the line will not burn. Used to monitor the battery voltage, to grasp the battery voltage status, can also be used for other products voltage measurement purposes. Note that the maximum input voltage can not exceed 30V, otherwise there is the risk of burning. Display devices are used bright LED digital tube, display stunning. Using automatic SMD process manufacturing, exquisite workmanship.
parameter
Opening size: 32 mm * 21 mm
Dimensions: 35mm * 23mm * 20mm
Product weight: 10 grams
Range: DC0.0-99.9V
Display: three 0.36 LED digital tube
Display color: red / green / blue / yellow / white
Measurement accuracy: +/- (1% + 1 words)
Supply voltage: DC4-30V (independent power supply)
Wiring instructions
Red line: power supply positive, need to access DC 4-30V range of power positive
Black line: the public negative, both the power supply negative, but also the reference reference negative
Yellow line: Measured signal input positive
Note
The head needs to be powered independently, the power supply range is DC 4-30V, red and black lines between the power supply, the meter will display 0.0, then the yellow line and the black line can be connected between the measured voltage, The voltage range is DC 0-99.9V
