MunHean MH Blue Multifunctional Digital Panel Meter
Model: MD-VAF | 3-Phase 4-Wire (3P4W) | Volt / Amp / Frequency (VAF) Analyzer
Product Overview
The genuine MunHean MH Blue MD-VAF Multifunctional Panel Meter is a premium, industrial-grade monitoring instrument designed for complete electrical network telemetry. Optimized specifically for 3-phase, 4-wire (3P4W) circuit configurations, this compact electronic unit tracks critical power parameters—including Voltage (V), Current (A), and Frequency (Hz)—on a single, scannable digital display interface. Engineered to eliminate the need for multiple separate single-dial analog meters, it delivers high-visibility readings under varying plant lighting conditions. This makes it an exceptionally reliable choice for modern industrial switchboards, factory distribution panels, and power management retrofits.

Key Features & Operational Benefits
- All-In-One VAF Monitoring: Combines multiple individual analog readouts into a single space-saving block, significantly lowering panel-cutting costs and installation time.
- High-Visibility LED Matrix: Designed with sharp, glowing numeric segments that allow field engineers to scan metrics from a distance, even in dimly lit electrical rooms.
- True-RMS Sensing Logic: Outfitted with sophisticated internal microprocessors that deliver accurate measurement data under noisy electrical loads and harmonic conditions.
- Robust Switchboard Housing: The heavy-duty plastic structural framing features standard rear mounting fasteners to stay firmly locked inside vibration-prone plant control enclosures.
