Three-phase energy meter Eastron SDM630MCT Modbus + 3 ESCT-T24 250A/5A sensor

A set consisting of a three-phase SDM630MCT Modbus meter and three ESCT-T24 250A/5A current sensors (transducers).

The three-phase meter SDM630MCT Modbus allows you to read electrical network parameters via the Modbus RTU bus.
Our Lan Controller series devices – LK3.5+, LK4, and LK4mini – support this meter, enabling integration with a remote monitoring system.

Compared to the simpler SDM72D-M model, the SDM630MCT Modbus meter offers access to a wider range of measurements, including voltage, current, and power for each phase separately, as well as total energy.

NOTE: Once the current transformer (CT) type is selected and confirmed in the meter menu, it cannot be changed!
This limitation is due to MID certification requirements.

Basic features

• Bidirectional measurement of active energy: consumed (import), fed into the grid (export), total.
• Bidirectional measurement of reactive energy: consumed (import), fed into the grid (export), total.
• Measurements of voltage, current, active power, and reactive power separately for each phase.
• Measurement of total active power (positive values ​​- energy consumption, negative values ​​- energy fed into the grid).
• Outputs: 2 pulse outputs, 1 RS-485 output with Modbus RTU protocol.
• Certified according to EU Directive 2014/32/EU.
• MID certificate number 0120 / SGS0142.

Main applications (using the LAN Controller)

• Monitoring of energy drawn from the grid (import) and fed into the grid (export), taking into account the phases at the connection point.
• Monitoring of other grid parameters at the connection point.
• Controlling the operation of additional loads depending on the energy balance on the meter.
