Product details

This Digital Voltage Display Module is tiny and compact with a red LED Display. The 0.28inch 0-100V Three Wire DC Voltmeter Red Panel requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink.

The red wire is to connect to the positive pole, the black wire is to connect to negative pole and the yellow/white wire is to connect to the positive pole of that source or another source across which we meant to measure the voltage. While measuring the supply voltage of another source make sure that negative pole is joined common. No need to worry even if there is any connection mismatch of the wires, the electric circuit won’t be a boom because it features reverse polarity protection.

Main Features:
● Easy wire connection, just need to connect two wires
● Built-in reverse polarity protection, it won’t be burnt even connect reversely
● The module will move the decimal position automatically according to different voltage to get the best accuracy
● It will correct to two decimal places when voltage is lower than 10V and correct to one decimal place when voltage is higher than 10V

Note: Do not use 30V voltmeter for 24V battery, for the left capacity is insufficient for the voltmeter when battery is fully charged. More over, higher pulse will be produced during charging and working.

Package Includes:

1 x Digital Voltage Display Module 0.36″ 3-Digit 2-Wire DC 4.5~30V Red Light LED
