The DEM-6MC three-phase DIN-rail multifunction energy meter provides 0.2% high-precision energy measurement and monitoring. It supports measurement and calculation of three-phase AC electrical parameters, cumulative energy recording, harmonic analysis, voltage and current unbalance analysis, multi-tariff energy metering, maximum demand measurement, digital inputs, alarm SOE record and relay outputs.
The meter is equipped with communication interfaces for integration with supervisory systems. It standard equipment RS485 interface with MODBUS protocol and 4G wireless communication with MQTT protocol, and optional other wireless modules (Wi-Fi, Zigbee, LoRa, IoT, etc.), enabling transmission of acquired measurement data and device status for centralized remote monitoring and management.
