10PCS 0.28 Inch Red Blue And Green Digital LED Mini Display Module DC 4.5V-30V 0-100V Voltmeter Tester Meter Motorcycle | Электронные

Function introduction:
1. Range: 2.5-30V (red) 2.6-30V (yellow) 2.6-30V (green) 3.2-30V (blue)
2. Equipped with two wires, the wiring is convenient and simple, and it is convenient to connect to the car/battery car/motorcycle line;
3. Note that the maximum input voltage cannot exceed 40V, otherwise there is a danger of burning.
4. When the voltage is lower than 3.0V, the display brightness will dim, but it will not affect the correct measurement
5. When measuring voltage below 10V, two decimal places are displayed; when measuring voltage above 10V, one decimal place is displayed. It can not only take care of the battery user's need for measurement accuracy, but also take care of the need for measuring higher voltages.

Two-wire voltage: DC4.5~30V (with reverse connection protection function)
Three-wire voltage: DC0~100V (with reverse connection protection function)
Working current: <30mA
Display mode: 0.28"LED, red blue green yellow (color optional)
Measuring rate: ≥200mS/time
Measurement accuracy: 3‰
 
Extreme working conditions:
Low working voltage: +2.4V
Maximum working voltage: +40V
Working temperature: -10～+65℃
Working humidity: 10～80% (no condensation)
Working pressure: 80～106kPa
Sun exposure: no direct exposure
 
 
For the best measurement accuracy, the voltmeter will automatically move the position of the decimal point according to the measured voltage.
When measuring voltages below 10V, two digits will be displayed after the decimal point;
When measuring voltage greater than 10V, one digit is displayed after the decimal point.
 It can not only take care of the battery user's need for measurement accuracy, but also take care of the need for measuring higher voltages.
This voltmeter can be used to measure the voltage of 18650 batteries, mobile phone lithium batteries, nickel-metal hydride battery packs and other battery packs.
 As well as the battery voltage of motorcycles, automobiles, etc., it can also be used for other voltage measurement purposes
