Eastron SDM72D-M-2-MID, Multifunction power meter, three-phase, 100A

Three-phase electricity meter that, in addition to measuring active energy (kWh) and power (W), supports communication via RS-485 RTU Modbus, allowing easy integration into monitoring and control systems. This model is designed for direct measurement up to 100 A, making it ideal for applications that require accurate energy monitoring in three-phase systems. The IP51 protection rating provides dust and water protection, ensuring reliability in demanding environments. Additionally, it supports bidirectional energy measurement, meaning it can record both energy consumed from the grid and energy fed back into the grid.

The meter complies with strict European standards and the requirements of directive 2014/32/EU for measuring instruments (MID), ensuring its accuracy and reliability.
