Digital Voltmeter Ammeter 30V 10A Red and Blue
A dual-display panel-mount meter that simultaneously shows DC voltage (red) and current (blue) on separate LED displays. Measures up to 30V and 10A with just 15mA quiescent current draw — ideal for monitoring battery systems, power supplies, and electronic projects in real time.
Each unit comes pre-calibrated with a trimpot on the back for fine-tuning after installation.
Specifications
- Voltage Range – 0–30V DC (red display)
- Current Range – 0–10A DC (blue display)
- Quiescent Current – ~15mA
- Calibration – Pre-calibrated, adjustable via rear trimpot
- Wiring – 2-pin harness (ammeter) + 3-pin harness (voltmeter)
Wiring: The thicker 2-pin harness is for the ammeter — wire it into the current return path to ground. The thinner 3-pin harness is for the voltmeter. Connect the ammeter red wire to your system and black to ground. The black wire on the 3-pin voltmeter harness can be left unconnected or tied to ground. The meter cannot display negative values.
Ideal For
- Battery system monitoring and diagnostics
- Power supply and bench setups
- Solar and charging system displays
- Panel-mount instrumentation
