Functional features:

Strong ability to prevent electricity theft and electromagnetic interference.

By using encryption cards and DES dynamic encryption algorithm, the system data is secure and reliable.

Adopting high-power magnetic holding relay, it has strong overload capacity, sensitive and reliable action.

Electricity consumption data can be transmitted back through meter reading cards, making it easier for management departments to timely collect and grasp electricity consumption information.

When the voltage of the line rises or the voltage of the main neutral line breaks and reaches the warning value, the electricity meter automatically shuts off, timely protecting the user's electrical equipment from being burned out. After 2 minutes of normal voltage, the electricity meter automatically resumes power supply.

When replacing the electricity meter, the data from the original meter can be extracted and transferred to the new meter through the meter replacement card, without causing any electricity disputes due to the replacement of the meter.

Power outage alarm function: When the remaining power reaches the set alarm value, the electricity meter automatically shuts off to remind users to reach the power supply in a timely manner.

Load control function: When the load exceeds the set value, the electricity meter will automatically cut off power. After the load decreases, the electricity meter will automatically restore power supply in about 5 minutes.

IC cards transmit data bidirectionally, with one meter and one card. If a card is lost, no data will be lost. When a new card is used, the original card will be automatically invalidated.

Control power on/off function: Through the 485 network, the management department can control the power on/off of users' electricity meters without leaving their homes.

Network meter reading function: Through the 485 interface, the electricity consumption of each meter can be recorded at any time, making it easier for management departments to calculate monthly electricity consumption.

One card function: It can be used for one card management with water meters. (Optional)
