Three-phase energy meter 63A class 1 MID M-Bus A9MEM3135

Three-phase energy meter with M-Bus communication

The Acti9 iEM3000 energy meter is an advanced device designed for precise measurement of electricity consumption in three-phase installations. DIN rail mounted, with an LCD display, it offers comprehensive network parameter monitoring, making it an ideal solution for both professional installers and end users. Thanks to its compliance with the MID directive, it ensures measurement reliability, and the M-Bus interface enables easy integration with building automation systems and remote reading.

Functionality and application

This model measures both active and reactive power, as well as active and reactive energy, providing a complete picture of network load. Support for four tariffs allows for cost optimization by billing consumption in different time intervals. The meter is designed for sub-billing applications and energy consumption monitoring in commercial and industrial buildings. A wide range of rated voltages (100…277 V N-L and 173…480 V L-L) and rated current of 63A make it versatile and can be used in various types of installations.

Key features and benefits

• High accuracy: Accuracy class B guarantees precise energy measurements, which is crucial for correct billing.
• M-Bus communication: Enables remote data reading and integration with energy management systems – saving time and costs associated with manual reading.
• Multi-tariff: Support for four tariffs allows for cost optimization by billing consumption depending on the time of day or day of the week.
• MID compliant: Ensures the legality of measurements and the possibility of using the meter in billing applications.
• Compact dimensions: Width of 5 modules (90 mm) makes it easy to install in switchboards with limited space.
• Versatility: Can be used in single-phase installations with neutral wire, three-phase and three-phase with neutral wire.
• Pulse output: Allows integration with external data logging systems or load control. The D0 output allows easy connection to BMS or other monitoring devices.
• LED signaling: Built-in LEDs indicate correct operation, overload alarms and communication status – quick diagnostics of problems.
• Solid construction: IP20 protection rating provides protection against touch and dust, increasing the durability of the device.
