Three phase four wire prepaid public electricity meter

Product Details

Three phase four wire prepaid utilityelectricity meterMain functions and features:
1. Standard IC card hardware encryption prepayment, the power supply department sells electricity in advance by selling power cards (IC cards) to collect electricity bills, and users buy before using.
2. Integrating fully digital metering, electricity display, prepaid control, and card reading,intelligentThe integration of multiple functions such as electricity theft prevention has extremely high reliability.
3. Overload protection. If the load exceeds the set maximum current for a continuous period of time, cut off the power supply circuit. The electric energy meter will automatically close after a certain period of delay.
4. The electric IC card is encrypted multiple times through software and hardware, fully ensuring the security, correctness, and reliability of data. Through special design, the electricity IC card records the remaining and cumulative electricity levels of the meter when the user inserts the card, as well as information on whether there is any electricity theft behavior.
5. A comprehensive checkpoint protection circuit can effectively prevent various malicious attacks on the checkpoint.
6. One meter with multiple cards, one card with multiple meters, unlimited access to the same area, power supply when inserting cards, power supply when unplugging cards. The electricity meter screen displays the remaining power in real-time.
7. When the remaining power reaches the pre alarm power level, the remaining power will flash to prompt the user to enter a new purchase power level.
8. When the remaining power in the energy meter is zero, the meter will automatically trip and interrupt the power supply. At this time, the user must bring the purchase card to the electricity sales department to purchase electricity (the power supply department can set an overdraft capacity, and after inserting the purchase card, the user can use a certain limit of electricity). After inserting the purchase card with effective electricity into the meter, the power can be supplied normally.
9. The application of magnetic holding relays not only improves the reliability of power-off actions and reduces power consumption after power-off actions, but also overcomes the disadvantage of contacts being unable to disconnect during long-term high current operation of relays.
10. Automatically save data during power outages and restore data automatically upon incoming calls.
11. The electricity sales management system consists of a computer, a dedicated IC card reader/writer, and billing management software.
12. By comparing and analyzing the recorded information, the management system can list users suspected of stealing electricity, in order to focus on inspection and reduce the workload of preventing and detecting electricity theft.
13. The wiring of the electric energy meter is reversed, and the electric energy meter can also measure correctly.
