Product Description
The M430 is a high-precision, panel-mounted dual digital voltmeter and ammeter module engineered for real-time monitoring of DC voltage and high-current electrical systems. Capable of measuring up to 100A when paired with an external shunt, this module features a crisp, dual-color LED display (Blue for Voltage, Green for Current) that provides immediate, high-contrast visibility even in low-light environments. Built with integrated fine-tuning calibration potentiometers, it allows technicians and hardware engineers to calibrate display readings for absolute accuracy. It features standard industrial panel-snap clips, making it a perfect component for power distribution units, battery charging stations, custom automotive dashboard panels, and test bench setups.
Pinout / Layout Connections
The module includes two separate wire harnesses on the rear side for power and measurement isolation:
-
Thin Wire Harness (Power Supply & Voltage Sensing):
-
Red Wire (VCC): Thin red wire connects to the positive power supply powering the meter itself (DC 4V to 30V max).
-
Black Wire (GND): Thin black wire connects to the system ground or negative supply terminal.
-
Yellow/White Wire (VIN): Thin measurement wire connects to the positive side of the target load or voltage source being monitored (DC 0V to 100V max testing range).
-
-
Thick Wire Harness (Current Sensing via External Shunt):
-
Thick Red Wire: Connects to the load terminal or the output side of the external current shunt resistor.
-
Thick Black Wire: Connects to the main power source negative supply line (System Ground Side) via the input terminal of the external shunt resistor.
-
Applications
-
Automotive & Marine Customization: Real-time battery and alternator monitoring for cars, trucks, motorcycles, and marine vessels.
-
Industrial Power Control: High-current monitoring panels for DC solar arrays, off-grid power banks, and battery backup banks.
-
Laboratory Test Benches: Variable DC bench power supply output display upgrades and custom diagnostic load stations.
-
Charging Infrastructure: Monitoring heavy-duty industrial battery chargers, electric vehicle (EV) charging setups, and power distribution racks.
