General description

The CMC series three-phase energy meters are compact and reliable instruments for the precise measurement of active and reactive energy in industrial, residential, or infrastructure installations.
They are designed for indirect connection via CT …/5 A current transformers and feature a 9-digit LCD display for reading total and partial values.

The M-Bus and Modbus RTU versions allow energy data to be transmitted to BMS, SCADA, or EMS software systems for centralized consumption monitoring. The devices support two tariffs (T1/T2), export/import metering, phase diagnostics, and automatic reporting of connection errors.

Compliant with EN 50470-1, EN 50470-3, EN 62053-23 standards, each model offers class II protection, IP51 degree in the panel and continuous operation up to 55 °C. The wide measuring range (from 0.003 A to 5 A on the CT side) makes these meters suitable for both medium-power systems and distribution networks with variable loads.
