Eastron SDM72D-M-2-MID Multifunctional electricity meter with bidirectional measurement, three-phase 100A

Eastron SDM72D-M-2-MID

A three-phase electricity meter that, in addition to measurement of active energy (kWh) and power (W), supports communication via RS-485 RTU Modbus, which allows easy integration into monitoring and control systems. This model is designed for direct measurement up to 100 A, which is ideal for applications where accurate consumption monitoring is required. IP51 protection provides protection against dust and water, ensuring reliability in harsh conditions. In addition, it supports bidirectional measurement, which means it can record both energy taken from the grid and energy returned to the grid.

The electricity meter meets the strict European standards and requirements of the Directive 2014/32/EU for Measuring Instruments (MID), which guarantees its accuracy and reliability.
