3-wire DC 0-100V 0.28 inch Ultra-small Digital Voltmeter Digital Display Adjustable Reverse Connection ProtectionItem NO.: 3-wire DC 0.28inch

0.28 inch Ultra-small Digital DC Voltmeter

Product Information:

The wiring is convenient and simple, making it easy to connect to the wiring inside the car/battery car/motorcycle. It has a reverse connection protection function, and the wiring will not be burned when reversed. It has a fine adjustment function. The module code is: AS is red, AG is green, AB is blue, and AY is yellow

Function Introduction:

1. Range: 0-100V

2. Equipped with three wires, the wiring is convenient and simple, making it easy to connect to the wiring inside the car/battery car/motorcycle;

3. It has a reverse connection protection function, and the wire connection will not be burned when reversed, with a fine adjustment function;

4. Please note that the maximum input voltage cannot exceed 100V, otherwise there is a risk of burning out.

When the voltage is below 3.0V, the display brightness will darken, but it does not affect the correct measurement

6. When measuring the voltage below 10V, two digits will be displayed after the Decimal separator; When measuring the voltage above 10V, a digit will be displayed after the Decimal separator.

7. It can not only meet the needs of battery users for measurement accuracy, but also meet the needs of measuring higher voltages.

Product Parameters:

● Working voltage: three wire [DC2.4-40V (with reverse protection function)]

● Detection voltage: three wire [0.0~100V]

● Working current:<30mA

● Display method: 0.28 "LED, red, blue, green, and yellow (four colors optional)

● Measurement rate: ≥ 200mS/time

● Measurement accuracy: 3 ‰

Extreme Working Conditions:

● Low working voltage:+2.4V

● Maximum working voltage:+100V

● Operating temperature: -10~+65 ℃

● Working humidity: 10~80% (without condensation)

● Working air pressure: 80-106kPa

● Sunlight exposure: no direct exposure

● For the best measurement accuracy, the Voltmeter will automatically move the position of the Decimal separator according to the different measured voltages. When measuring the voltage below 10V, two digits will be displayed after the Decimal separator; When the measured voltage is greater than 10V, one digit will be displayed after the Decimal separator. It can not only meet the needs of battery users for measurement accuracy, but also meet the needs of measuring higher voltages.

● This Voltmeter can be used to measure the voltage of 18650 batteries, mobile phone lithium batteries, Nickel–metal hydride battery and other battery packs, as well as the voltage of motorcycles, cars and other batteries, and can also be used for other voltage measurement purposes

Main Features:

1. Good product stability and high measurement accuracy

2. The appearance adopts standard size, which is convenient for installation

3. The power supply adopts polarity protection circuit
