Mini Digital DC Voltmeter 0-100V 3 Wire LED Display 7N028-V4.0
Price in Sri Lanka

This is a 100-volt digital voltmeter with a 0.36-inch LED display that works with input voltages ranging from 3 to 30 volts. The metre's PCB assembly contains two mounting holes, allowing users to easily attach it to a panel or other surface.

This digital voltage meter comes with three wires. Only two wires are required to connect this device to the target circuit for voltages up to 100V, and the same DC voltage utilised by the target circuit is used to power this voltmeter. For applications requiring measurements of more than 30 volts, three wires and an additional power supply are used.
