3P+N Smart Energy Monitor with 3 CT Clamps, Modbus RS485, 120 A, DIN Rail

This smart energy monitor uses Modbus RTU over RS485 to integrate three-phase-with-neutral (3P+N) or single-phase energy measurements into industrial control systems. The DIN-rail monitor and three included 16mm split-core current transformers measure each phase independently without requiring the existing conductors to be disconnected.

Monitoring and communication

• Measures voltage, current, active power, electricity consumption and frequency in real time, with current measurement up to 120A per phase.
• Modbus RTU (RS485) provides stable wired communication for industrial or commercial installations. A reset button is provided.
