0.56-Inch Green LED AC Voltmeter – 70V-500V Two-Wire Digital Voltage Display Module for AC Mains and Industrial Monitoring

Product Description

Upgrade your power monitoring setup with the 0.56-Inch Green LED AC Voltmeter. This robust two-wire digital display module is engineered for direct measurement of AC mains and industrial power supplies within the wide range of 70V to 500V. Featuring a high-visibility green 7-segment LED display with a matte-finish glass cover, it ensures lucid readability even in bright environments. At Robogears, we recommend this module for its "power-from-source" design, meaning it requires no external power supply to function. Built with reverse connection protection and an auto-shifting decimal point for maximum precision, it is the ideal compact solution for real-time AC voltage tracking in control panels, motor generators, and distribution boards.

Detailed Key Features

• Wide AC Range: Measures from 70V up to 500V AC, covering everything from standard single-phase mains to higher industrial voltage levels.

• Two-Wire Simplified Wiring: Connects directly to the voltage source being measured—no separate auxiliary power supply needed.

• Auto-Precision Scaling: The decimal point automatically shifts based on the voltage magnitude to provide the highest possible measurement accuracy.

• Lucid Day-Time Visibility: The matte finish on the display glass reduces glare, making the green digits clearly visible during daytime or under harsh workshop lighting.

• Integrated Safety: Includes reverse connection protection to prevent damage during accidental miswiring, ensuring industrial-grade reliability.

All Technical Details

• Mounting Type: Panel Mount (Standard Snap-in Design).

• Dimensions: Optimized for standard 0.56-inch cutouts.

• Consumption: Ultra-low power draw (<20mA) minimizes impact on the measured circuit.

• Accuracy Calibration: Pre-calibrated for ±1% error margin at standard AC frequencies (50/60Hz).

• Display Refresh: High-speed 300ms refresh cycle for near-instantaneous voltage feedback.
