DC 0-99V 3 Wire LED Digital Display Panel Mount Voltmeter Car Boat Caravan Green


9 in stock

Back In Stock

These have a Large 0.56″ Display

These high quality LED voltmeters are ideal for DC voltage measurement up to 99.9 volt.

Remember this is the 3 wire Version module, which means with the supply voltage maintained, and with the measuring voltage at 0v the display will still be on, so you can see the full swing of the measuring voltage from 0v to 99.9v. Unlike 2 wire versions where the display will start to dim and turn off when the measuring voltage starts to drop below 5v, since the 2 wire version uses the measuring supply to also power the unit.

Supplied in a professional and well-finished case, they will fit into your front panel – providing a professional looking finish!
