Description

The Eastron SDM630MCT is a high-specification multifunction energy meter designed for DIN-rail mounting in transformer-operated three-phase systems. By utilizing external 1A or 5A current transformers (CTs), the SDM630MCT can monitor electrical loads far beyond the capacity of direct-fed meters, making it the preferred choice for industrial mains and large-scale facility management. With MID B+D certification, it ensures billing-grade precision (Class 0.5s) for fiscal sub-metering applications while offering real-time data on over 40 electrical parameters.

Core Capabilities

Scaleable Current Range Programmable CT primary ratios allow for monitoring of virtually any high-current industrial load.
THD & Harmonic Analysis Monitors Total Harmonic Distortion for both voltage and current to safeguard industrial equipment.
Import/Export Tracking Measures active and reactive energy in both directions, critical for renewable energy integration.
Industrial Comms Equipped with Modbus RTU (RS485) and pulsed outputs for seamless integration with BMS and DTUs.

Primary Applications

• Industrial Sub-metering: Efficient energy allocation for heavy machinery, HVAC systems, and manufacturing floors.
• Commercial Energy Billing: Accurate, MID-certified energy measurement for shopping malls and multi-tenant offices.
• Smart Buildings: Remote energy monitoring via LoRaWAN gateways or local building automation systems.

Technical Integration

The SDM630MCT supports standard 35mm DIN rail mounting and is compatible with 1P2W, 3P3W, and 3P4W electrical systems. It features a high-visibility backlit LCD and intuitive buttons for easy field configuration of CT ratios and Modbus parameters.
