Three-phase energy meter 5A class 0.5S Modbus A9MEM3250

Three-phase energy meter with Modbus interface – precise measurement and remote reading

The A9MEM3250 energy meter is an advanced device designed to measure electricity consumption in three-phase installations. Mounted on a DIN rail, it offers reliable measurement with a class of accuracy 0.5S, making it an ideal solution for both commercial and industrial applications. Modbus communication enables easy integration with monitoring and energy management systems, providing remote data reading and consumption analysis.

Functionality and application

The device is designed to measure active power consumption in networks with a rated voltage of 100 to 277 V (phase-neutral) or 173 to 480 V (phase-phase) and a rated current of 5A. The meter design allows for direct or semi-direct mounting using external current transformers. The width of 5 modules facilitates integration with existing electrical panels. Thanks to the digital display and Modbus communication, this meter is used in sub-billing systems, partial measurements and monitoring of energy consumption in public buildings, industrial plants and other facilities requiring precise energy billing.
