Description

Overview

A round panel-mount voltmeter with a bright LED digital readout, made to sit in a dashboard cut-out and be read at a glance. It is waterproof, with blue, red or green digits in a DC 3.3-30V or DC 12-24V range.

Specifications

  • Display: LED digital numeric
  • Range: DC 3.3-30V or DC 12-24V, by variant
  • Colours: blue, red, green
  • Body: round, panel mount
  • Sealing: waterproof
  • Serves 12V and 24V systems

Purpose

Charging and battery faults show up as a drifting voltage long before anything stops working. A permanently fitted gauge keeps that number in view.

Applications

  • Car, van and truck dashboards
  • Motorcycle battery monitoring
  • Camper and boat panels
  • Solar battery-bank displays
  • 12V and 24V pump or winch setups

How to Use

  1. Pick the range bracketing your system: DC 12-24V for vehicles, DC 3.3-30V for wider coverage.
  2. Choose digit colour, cut a round hole to suit the body, seat the bezel.
  3. Positive lead to the measured point, negative lead to ground.
  4. Compare against a trusted meter at rest and under load.
  5. Stay inside the rated range; a 12-24V unit on a higher-voltage bank will be damaged.
