EASTRON SMART METER, three-phase energy meter SDM630 MCT with Modbus

The SDM 630 MCT is a three-phase electrical energy meter designed for accurate measurement of energy consumption and monitoring of key electrical parameters. The meter is mounted on a DIN rail and operates with current transformers (CT) 1/5A, requiring a backup AC or DC power supply.

With the built-in RS485 Modbus RTU interface and pulse outputs, the meter allows remote data reading and integration with energy monitoring and management systems.
