0.36 Inch 0-100V Three Wire DC Voltmeter

This is a 100 volt digital voltmeter with a 0.36 inch LED display that works with input voltages ranging from 3 to 100 volts. The metre's PCB assembly contains two mounting holes, allowing users to easily attach it on a panel or other surface.

This digital Voltmeter comes with 3 wires. Only two wires are required to connect this device to the target circuit for voltages up to 30V, and the same DC voltage utilised by the target circuit is used to power this voltmeter. For applications requiring measurements of more than 30V, three-wires and an additional power supply are used.

Package Includes:

1 X 0.36 Inch Three Wire DC Voltmeter

Applications:

• Project power supply monitoring up to 30V
• Monitor battery voltage of a car, motorcycle, truck or bus which have 12v /24v batteries
• Monitor UPS, Home Inverter Batteries of 12V/24V or Solar Panel voltage.
