0.36'' DC0-100V LED Mini Digital Voltmeter Red LED

This voltmeter is measured in a range of 0-100V, which is a measuring signal and cannot be used as a power source for the voltmeter. So this voltmeter needs to be supplied by the outside to provide a DC voltage of 4.5-30V as a power supply. In the three lines, the black line is the common negative pole, the white line is the voltage positive, the red line is connected to the positive electrode of the work supply, and the balance is negative in the table.

The voltmeter working power supply voltage of 4.5-30V, 30V is the highest limit, please pay attention to leave the table enough allowance, avoid the spark voltage, power supply ripple or other mutations cause permanent damage to the voltmeter too high voltage.

This voltmeter is not moisture proof, waterproof, or shockproof.
