Three-phase energy meter 125A class 1 Modbus A9MEM3350

Three-phase energy meter for precise measurement and monitoring

This three-phase Acti9 iEM3350 energy meter is an advanced device designed to measure electricity consumption in installations with a current of up to 125A. DIN rail mounted, it offers reliable operation and measurement accuracy, making it an ideal solution for both professional installers and end users. Thanks to the Modbus interface, it enables integration with monitoring and energy management systems, providing full control over consumption.

Features and application

This meter finds application in a wide range of electrical installations, from commercial buildings to industrial plants. Its compact dimensions (7 module width) allow for easy mounting in switchboards. Equipped with a digital display, it presents key parameters such as active energy, voltage and current. Additional LEDs indicate the status of power supply and communication. The meter is designed for direct current measurement, eliminating the need for additional current transformers in many applications. Accuracy class B ensures measurement reliability in accordance with IEC 62053-21 and IEC 61557-12 standards.

Advantages and benefits

• Versatility: Supports 50 Hz and 60 Hz networks and voltages from 100 to 277 V (phase-neutral) or from 173 to 480 V (phase-phase).
• Modbus communication: Enables remote data reading and integration with building automation systems (BMS) or energy management systems.
• Accuracy: Accuracy class B guarantees precise energy consumption measurements.
