RS485 Modbus Three-Phase AC Power Meter – Voltage, Current, Power & Energy
A compact three-phase AC power and energy acquisition module designed for accurate electrical measurement and seamless integration with PLC, SCADA, BMS, and energy management systems via RS485 Modbus RTU.
This three-phase AC power meter is designed to measure and monitor key electrical parameters in three-phase power systems, including voltage, current, power, power factor, and energy consumption. Using dedicated measurement chips with digital sampling technology, it delivers reliable RMS measurement accuracy for industrial and commercial applications.
The device supports RS485 communication with the Modbus RTU protocol, allowing easy integration into AMR, EMS, PLC, SCADA, and data logging systems. Its compact DIN-rail mounting design simplifies installation in control panels, switchboards, and distribution cabinets.
Compatible with both solid-core and split-core current transformers, the meter is suitable for new installations and retrofit projects, including live upgrades where shutdown is not practical. Built with industrial-grade components, isolation protection, and strong anti-interference design, it ensures stable long-term operation in demanding environments.
