EASTRON SDM630-MCT V2 Three-Phase CT Operated Energy Meter with Modbus RTU, 5/6A MID Certified 32105

Electrical engineers and facility managers use the EASTRON SDM630-MCT V2 to monitor power consumption in commercial buildings and industrial panels. This three-phase energy meter connects via current transformers (CTs) and provides accurate measurements for billing and energy management.

Key specifications

• Three-phase measurement (3P4W/3P3W)
• CT operated with configurable 5A or 6A secondary current
• Voltage inputs: 3x 230V AC (L-N), 3x 400V AC (L-L)
• Active energy accuracy Class 1 (MID B), reactive energy Class 2
• RS485 Modbus RTU communication
• Two configurable S0 pulse outputs
• Backlit LCD display
• DIN rail mounting, 4-module width
• Operating temperature -25°C to +55°C
• Measures kWh, kvarh, V, A, Hz, PF, kW, kvar, kVA

Why choose it

MID certification ensures legal compliance for sub-billing in the EU. The Modbus interface integrates with building management systems, and the pulse outputs enable connection to external monitoring devices. Its compact DIN rail design fits standard distribution boards.

Ideal use cases

• Sub-metering in commercial buildings
• Energy monitoring in industrial control panels
• Integration with SCADA or BMS via Modbus
• Cost allocation for tenants or departments

Good to know

The meter requires external current transformers (not included) with 5A or 6A secondary. Configuration of CT ratio and communication parameters is done via Modbus or the front panel buttons.
