Eastron Electricity meter SDM630MCT V2 MID, 1/3 phases x/5A, no coils

A modern smart energy meter (V2 version) designed for single-phase and three-phase indirect measurement using current transformers (CT) with a 5 A secondary (e.g., 100/5 A, 250/5 A). It allows detailed monitoring of a wide range of electrical parameters, including voltage (V), frequency (Hz), current (A), power factor (PF), power (kW/kVA/kVAr), energy (kWh/kVArh), and energy flow direction (import/export). The device provides accurate measurement and clear display of characteristics in single-phase two-wire (1p2w), three-phase three-wire (3p3w), and three-phase four-wire (3p4w) networks. For integration with higher-level systems, it is equipped with a RS-485 communication port (Modbus RTU). Current transformers (CT) are not included in the package.
