Polyphase Power Smart meter was designed with chips and technology. Under the premise of ensuring quality and stability, it also has the advantages of small size and convenient installation. The instrument uses a large-screen multi-line LCD liquid crystal display, which can communicate with RS485. The communication interface and the host computer and equipment realize the data exchange function, and realize the digital and networked intelligent measurement control system.

It greatly facilitates the automatic management of electricity consumption, mainly for the three-phase voltage, three-phase current, and active power in the power line. Real-time measurement and display of power, reactive power, power factor, frequency, electricity and other parameters. Limit alarm, switch input and output functions, which can replace conventional measurement indicating instrument, electric energy meter, multi-function.

The meters and related auxiliary units are widely used in various control systems, energy management systems, substation automation, distribution network automation, smart buildings, smart switchboards, switch cabinets.

Product features
