I believe everyone is familiar with the three phase electricity meter , so do you know what its super capacity alarm is like? How is the electric card used?

Over-capacity alarm: During the operation of the meter, if the "alarm indicator" flashes quickly, it will warn the user that over-capacity has been used; if the user is set to the over-capacity power-off limit mode, the over-capacity power consumption will be 30 seconds later, The gate will be opened for 3 minutes, and the power supply recovery time will be displayed in a countdown mode (180 seconds); if the user inserts the card, the power supply can be restored immediately.

Electricity card usage: Insert the electricity purchase card into the cardholder. If it is a valid card, the meter will automatically read the data into the meter. The LCD meter display will display in turn: electricity purchase, total purchase electricity, number of electricity meters, alarm electricity, credit limit, Limited capacity power. Then take the card and keep the electric card properly.

Besides, the same is true for kilo watt-hour meter .
