The main functions of the multi-user combination prepaid electricity meter networking type are:

1. Equipped with overload protection function, when the user's load exceeds the allowable maximum load, the user will automatically power off for protection.

2. Adopting large-scale integrated circuits specifically designed for electric energy meters and high-precision current transformers, with low heat generation, good electrical isolation effect, strong overload capacity, and longer service life. Low power consumption, simple meter structure, and stable performance.

3. Adopting modular design, each household measures independently, displays centrally, and does not affect each other.

4. Equipped with remote networking power on/off function, it is conducive to collecting electricity bills.

5. By connecting to the internet, users can check the electricity usage and power on/off status of each household at any time.

6. The communication circuit design is stable and can effectively avoid signal interference caused by lightning strikes and other factors.

7. It can directly display the room number and cyclically display the electricity consumption of each household, with clear and intuitive display for users to easily read the electricity consumption.

8. It has real-time power display function, which can display the user's electricity load in real time and facilitate on-site meter calibration.

9. The internal power supply is three-phase, but the power supply is out of phase, and the electricity meter is working as usual; It has the function of indicating power phase loss.

10. The watch case is formed by one-time stamping, with good sealing performance and equipped with lead seal, in compliance with GB/T17215-2002 standard.

11. Using dedicated wiring terminals and double bolt crimping, it is reliable to use.
