0.56″ LED Digital Voltmeter | DC 0V-100V | 3-Wire Precision Panel Meter
Product Overview
The 0.56″ 3-Wire Digital Voltmeter from Pro Tronix is a versatile and reliable tool for real-time voltage monitoring. Unlike 2-wire versions that are powered by the signal they measure (limiting their range), this 3-wire design allows the meter to be powered independently. This enables it to measure voltages as low as 0V DC, making it perfect for monitoring variable power supplies or discharging batteries.
The display features large, easy-to-read digits and a high refresh rate. With its built-in mounting “ears,” it snaps easily into rectangular cutouts on plastic or metal project boxes, providing a professional look to any custom electronic build.

Key Features
-
Ultra-Wide Range: Measures from 0V up to 100V, suitable for everything from logic levels to large battery banks.
-
Independent Powering: Because it is powered by a separate DC source (4.5V-30V), it can accurately measure very low voltages that would otherwise dim or shut off the display.
-
High Visibility: The 0.56″ LED digits are bright enough to be seen from across a room, even in low-light conditions.
-
Simple Installation: Features a compact panel-mount design with pre-soldered 15cm leads for quick integration.
Common Applications
-
Bench Power Supplies: Providing a digital readout for DIY or modified lab power units.
-
Electric Vehicles & Scooters: Monitoring the voltage of 36V, 48V, or 60V battery packs in real-time.
-
Solar Systems: Keeping track of battery charge levels in off-grid solar energy setups.
-
Industrial Monitoring: Tracking the health of DC control circuits and industrial battery backups.
💡 Wiring Tip: > * Red Wire: Power Supply Positive (4.5V – 30V).
Black Wire: Common Ground (Negative).
White/Yellow Wire: Voltage Measurement Point (0V – 100V).
