The Eastron SDM630MCT MODBUS MID V2 is a high-precision three-phase multi-function energy meter compatible with both single-phase and three-phase networks. It uses the latest microprocessor technology and has a blue backlit display showing 16 measured parameters, including a negative power reading to indicate reversed CT installation or incorrect connection. Built-in RS485 Modbus RTU and pulsed outputs make it fully compatible with BMS and remote monitoring platforms.

The unit ships with three ESCT-T24 250/5A split-core current transformers. Their split-core design permits current measurement via magnetic field induction without disconnecting the primary conductor, allowing fast and safe installation. An internal precision burden resistor provides a safe low-voltage secondary output. Four-module DIN rail mounting fits standard distribution boards.
