All about the product
SDM 72 DM MID Modbus Three-Phase Energy Meter
Purpose
The “VCX/Eastron” three-phase energy meter “SDM 72 DM MID Modbus” is a modern digital meter designed for direct electrical energy measurement in three-phase devices up to 100 A. The device measures active energy (kWh) and power (W), and due to bi-directional measurement, it is suitable for both consumer devices and PV generation (measuring consumed and exported energy). The integrated RS485 interface with the Modbus RTU protocol allows remote data reading and integration with energy monitoring systems, building automation, and BMS systems. The illuminated LCD screen ensures easy parameter reading even in poorly lit distribution panels.
Application
- Energy measurement in three-phase 3×230/400 V installations in residential, commercial, and industrial buildings.
- Energy consumption control in high-rise distribution boards, installation of individual meters for apartments, commercial premises, and tenants.
- Monitoring the energy production and consumption of photovoltaic systems (measuring energy import and export).
- Integration with energy monitoring systems (Modbus RTU), building management systems, PLC controllers, data loggers.
- Commercial applications requiring compliance with MID regulations – issuing energy bills among end users.
Key Features
- Three-phase digital energy meter, mounted on a 35 mm DIN rail.
- Current range up to 100 A (direct connection – without transformers).
- Measurement of active energy (kWh) and active power (W), indicating the direction of energy flow (import/export).
- Bi-directional measurement – ideal for photovoltaic and microgeneration systems.
- RS485 interface with Modbus RTU protocol for remote data reading and system integration.
- Pulse output for energy calculation by external systems.
- Illuminated, clear LCD screen displaying key parameters.
- Accuracy better than Class 1/B – reliable energy measurement.
- Compliance with MID regulations – can be used for financial energy settlements.
