Description

The Eastron SDM630-Modbus is a versatile, DIN-rail mounted multifunction energy meter designed for high-precision monitoring of three-phase electrical systems. Supporting direct loads up to 100A, it eliminates the need for external current transformers, simplifying installation in space-constrained distribution boards. With MID B+D certification, the SDM630-Modbus is authorized for fiscal sub-metering and billing applications across Europe, providing reliable data on over 40 electrical parameters including total harmonic distortion (THD), bi-directional energy (Import/Export), and demand.

Core Capabilities

Multi-Parameter Analysis Tracks kWh, kVarh, Watts, Amps, Volts, PF, Frequency, and THD for complete system oversight.
Bi-Directional Metering Perfect for solar PV and EV charging by measuring both Import and Export energy flows.
RS485 Modbus RTU Enables remote data collection and integration with Building Management Systems (BMS) and LoRaWAN DTUs.
Backlit LCD Display High-visibility screen with intuitive touch buttons for easy local parameter navigation.

Target Applications

• Commercial Sub-metering: Accurate energy billing for office spaces, retail units, and industrial facilities.
• EV Charging Stations: Reliable energy measurement for commercial EV chargers and residential complexes.
• Energy Management: Identifying load profiles and inefficiencies to optimize building energy performance.

Technical Integration

The SDM630-Modbus supports 1P2W, 3P3W, and 3P4W wiring configurations, making it compatible with various global electrical systems. Housed in a 4-module (72mm) DIN-rail enclosure with IP51 protection, it is designed for ease of installation. Remote configuration is available via free Eastron software, allowing for quick setup of Modbus parameters and pulse output rates. For large-scale integration projects or LoRaWAN energy monitoring architecture, contact the ShopIoT engineering team.
