Energy Meter iEM3155 63 A Class 1 Modbus MID

The iEM3155 energy meter, reference A9MEM3155 by Schneider Electric, is an advanced tool for energy monitoring, designed to accurately measure active, reactive, and apparent energy in three-phase and single-phase electrical systems. This compact meter, with a width of just 90 mm and a height of 95 mm, is easily installed on a DIN rail, making it ideal for sub-metering, energy management, and optimising energy consumption in residential, commercial, and industrial environments.

Applications:

The iEM3155 is designed to be an efficient and accurate solution for energy monitoring and sub-metering in electrical networks. With its ability to measure active and reactive energy in four quadrants, it is particularly useful in installations where detailed energy consumption control is required, both in single-phase and three-phase systems. The meter is ideal for installations where energy efficiency programmes need to be implemented, savings opportunities identified, or for the accurate billing of consumption in shared installations such as offices, light industries, or commercial complexes.

Main Features:

• Class 1 Accurate Measurement: The iEM3155 has a Class 1 accuracy according to the IEC 62053-21 standard for active energy measurement, ensuring reliable readings that meet the most demanding international standards. This is crucial for applications where high accuracy in electricity consumption measurement is required, such as sub-metering or real-time monitoring of large installations.
• Multi-tariff Capability: This meter can handle up to 4 tariff programmes, allowing for the differentiation of consumption rates throughout the day or according to demand, ideal for energy management in installations with different tariff periods.
• Modbus Compatibility: The meter includes a Modbus 485 communication port, allowing easy integration with building management systems and other remote monitoring systems, facilitating data centralisation and control of electrical consumption. Additionally, it features a programmable digital output for use in control or additional monitoring applications.

Technical Specifications:

• Nominal Current: The meter is designed for a nominal current of 63 A, making it suitable for a wide range of applications, from small installations to higher consumption systems in light industries.
• Nominal Voltage: Compatible with systems from 100 to 277 V AC and 173 to 480 V AC, the iEM3155 can operate in both single-phase and three-phase networks, ensuring its flexibility in different types of installations.
• LCD Display: The meter features a clear LCD display that provides instant readings of key parameters such as active energy, reactive energy, current, and voltage. It also includes LED indicators for local signalling, facilitating accuracy verification, overload alarms, and communication status.

Additional Advantages:

• Four Quadrant Energy Monitoring: The iEM3155 measures energy in four quadrants, meaning it can measure both imported energy and exported energy, making it ideal for installations that generate their own energy, such as those including solar panels or generators.
• Compact Design: With a size of just 5 modules of 18 mm, the meter is extremely compact, occupying minimal space in the electrical panel, facilitating its integration into new or existing installations.
• MID Certification: This meter is certified in accordance with MID regulations, ensuring its validity for sub-metering and official billing applications, being a reliable option for managing electrical consumption in shared installations.

Additional Specifications:

• Class 1 (IEC 62053-21) and Class B (EN 50470-3) Accuracy Class: This ensures the accuracy of the active energy measured by the device, ensuring compliance with the highest quality standards for sub-metering applications.
• Programmable Digital Input and Output: The meter includes a digital input and output that can be used to generate signals based on certain events or to emit consumption pulses, allowing for flexible integration into control systems and remote monitoring.
• Network Frequency: Designed to operate in both 50 Hz and 60 Hz systems, ensuring compatibility with electrical networks in different regions.
• International Certifications: The meter holds various certifications, including CE, UL, EAC, and MID, ensuring compliance with international safety and performance standards, providing confidence and reliability in its use.

Benefits of the iEM3155:

• Efficient Energy Management: Thanks to its precise and multi-tariff monitoring capability, the iEM3155 allows businesses and building managers to identify energy saving opportunities and manage consumption efficiently.
• Easy Integration: With its Modbus port and compact size, the meter can be easily integrated into energy and building management systems, facilitating installation and allowing for centralised control.
