Intelligent electricity meter for single-phase and three-phase measurement. Measured parameters include voltage (V), frequency (Hz), current (A), power (kW/kVA/kVAr), import, export , and total energy (kWh/kVArh). The device can also measure maximum current and power consumption. This device measures and displays characteristics of single-phase two-wire (1p2w), three-phase three-wire (3p3w), and three-phase four-wire (3p4w) current in the network. There is a RS-485 communication port Modbus RTU available.
