The three-phase multifunctional rail type electric meter is mainly composed of a microcontroller processing system, a liquid crystal display screen, a far-infrared communication system, an internal system structure, and a body. These parts constitute the basic components of the electric meter. It can be seen that the structure of the electric energy meter is relatively simple and easy to operate, without the need for professional personnel to guide and read the user manual. It can be directly operated and used. Due to its simplicity in circuit design and specifications, it has extremely high safety and reliability during use, while also achieving high precision. The biggest feature of this energy meter is the combination of software and hardware, which allows the device to measure up to 20 different electrical parameters such as current, voltage, power, etc. during operation.

The addition of communication function to the three-phase multifunctional rail type electric meter gives it excellent performance characteristics in terms of anti-interference and anti attack. It can be used in different working environments and conditions with large temperature differences, and can ensure long-term stable operation and work. The display screen of the electric energy meter adopts a high-quality LCD display screen, which can clearly and accurately display data such as current and voltage. The display screen can display 8 digits, in addition to 6 integers, it can also display 2 decimal places, and can support backlight display function
