Digital Voltmeter 3 - 32V

Compact size and easy to use digital voltmeter. Measure voltages between 3V and 32V direct current (DC) quickly and easily with this portable voltmeter, which can be used in countless situations, such as electronic projects, power systems, automobiles, solar energy systems, etc.

Composed of a 0.34'' LED display without housing and an internal circuit to perform the measurement, you can clearly see the measurement without the need to power the device. That is, you will not need to apply external power, since the voltage required for its operation will be taken from the voltage source itself to be measured. This voltmeter also has a protection system in the case of connecting the cables in reverse (without respecting the polarity). You can also fix the voltmeter to any surface without any problems thanks to the two support brackets present.

Cautions

The measuring range of this voltmeter is from 3 to 32V, being 32V the maximum operating voltage of the voltmeter, so it is advisable to leave enough margin when working to avoid permanent damage to the device.

Connection

This voltmeter has 2 wires, the black wire is the communal negative pole and the red wire is connected to the positive pole of the power supply. The measuring circuit and the negative pole of the power circuit are common.
