The DEM-6MC multi-function energy meter features high-accuracy power metering and monitoring, ideal for prepaid management systems in residential, industrial, and commercial applications. It integrates a class 0.2 precision measurement module for real-time acquisition of three-phase voltage, current, power, energy, current unbalance, and harmonic data. Measurement data is transmitted via RS485 or wireless modules (WIFI, 4G, Zigbee, LoRa, IoT) for centralized remote monitoring and management.
