Eastron DIN Rail Mounted Three Phase CT SDM630MCT

The Eastron SDM630MCT is a high-performance DIN rail mounted three-phase energy meter designed for accurate electrical energy monitoring in commercial, industrial, and renewable energy installations. Operating with external current transformers (CTs), this multifunction energy meter delivers precise measurement of energy consumption and electrical parameters, making it ideal for sub-metering, energy management systems, tenant billing, building automation, and power monitoring applications. 

Designed for flexibility and reliability, the SDM630MCT supports three-phase four-wire, three-phase three-wire, and single-phase systems. The meter provides comprehensive real-time monitoring of active energy (kWh), reactive energy (kVarh), voltage, current, active power, reactive power, apparent power, frequency, power factor, demand, and total harmonic distortion (THD).

The integrated backlit LCD display allows easy viewing of system measurements, while RS485 Modbus RTU communication enables seamless integration with Building Management Systems (BMS), Energy Management Systems (EMS), SCADA platforms, and industrial automation networks. Bi-directional energy measurement supports both imported and exported energy monitoring, making it suitable for solar PV and other distributed energy systems.
