Three-phase energy meter 5A class 0.5S MID M-Bus A9MEM3235

Three-phase energy meter for precise measurement and efficient energy management

This three-phase energy meter, with a Class 0.5S accuracy and MID compliance, is a reliable solution for both installers and end-users. Designed for DIN rail mounting, it measures active and reactive energy in 50 and 60 Hz networks. Thanks to the M-Bus interface, it enables remote data reading and integration with energy consumption monitoring systems.

This meter is ideal for applications requiring high measurement accuracy, such as sub-billing or load profile analysis. Multi-tariff support with external or internal control allows for energy cost optimization. Robust construction and IP20 protection ensure reliable operation in various environmental conditions.

Features and benefits

• High accuracy: Accuracy class 0.5S guarantees precise active energy measurements, which is crucial for correct billing.
• MID compliance: The MID certificate confirms the metrological legality of the device, allowing its use in billing applications.
• M-Bus communication: The M-Bus interface facilitates remote data reading and integration with building automation systems (BMS) and energy management systems. This saves time and costs associated with manual reading.
• Multi-tariff: The ability to configure multiple tariffs allows for optimizing energy consumption depending on the time of day or day of the week – particularly important for businesses and commercial facilities.
• Wide range of voltages and currents: The meter works with networks with a rated voltage of 100 to 480 V and a rated current of 5 A, ensuring its versatility.
• Pulse output: The electrical pulse output (D0) enables recording energy consumption by external systems or devices.
• Compact dimensions: A width of 5 modules (90 mm) makes it easy to mount in electrical panels with limited space.
• Robust construction: IP20 protection provides protection against touch and dust, increasing the durability of the device.

Technical parameters and application

The A9MEM3235 meter is designed to measure electrical energy in three-phase installations (including the neutral wire). It can be used in both consumption and energy return circuits (e.g., in photovoltaic installations). Thanks to the wide range of rated voltages (100…277 V N-L / 173…480 V L-L) and rated current of 5A, it is compatible with various types of electrical installations. It has 9 counter positions to display current parameters and supports up to 500 pulses per kWh/kvarh. Additionally, the lack of a counter lock makes the device flexible in application – although it does not meet the requirements where a legal lock is required.
