Mini Voltmeter LED 0-100V DC 0.28 Inch 3 Wire Yellow/Orange ***LOCAL STOCK***

Mini Voltmeter LED 0-100V DC 0.28 Inch 3 Wire Yellow/Orange

This is a mini DC voltmeter with LED display. Thanks to the small dimension it can be easily integrated into your project. It has three wires (yellow, red and black) and can measure up to 100V.

High precision
Reverse connection protection
The decimal point is automatically shifted
Able to adjust voltage resistance - Turn clockwise to lower voltage, it can work directly in 5v, 9v, 12v, 24v.
Three-wire connection, but it can also change three lines to 2-wire connection.

Usage Guide

This voltmeter has three wires, and they are:

Yellow: Anode of measured voltage
Red: Anode of power supply for the voltmeter
Black: Common cathode of measured voltage and power supply

If the actual measured voltage is higher than 3.5V and is lower than 30V, you can also join the red and yellow wires. In this case the measured voltage will also work as the power supply for the voltmeter.

Displays are available in other colours.
