Product Features:

WL type multi-user intelligent energy meter

1、 Remote reading of real-time data from the table (remaining battery level/cumulative battery level).

2、 Real time power outage: Through the 485 network, the property management department can control the power on and off of users' electricity meters without leaving their homes, and the data inside the meters will not be lost.

IIIClearing the entire table/single table: The software can be used to reset the entire table or single account.

4、 Set the time period through the clock to give away battery power.

5、 SMS power purchase reminder function: When the remaining power in the user's meter does not reach a certain value (which can be set through software), the power sales system can send a text message to the user through the SMS platform to remind them that the remaining power in the meter is low and to purchase electricity in a timely manner.

6、 Implement stop and refund function: Implement user stop and refund function through software operation.

7、 Report query: Real time query of sales records, electricity sales records, and electricity consumption statistics, which can be imported into Excel spreadsheets.

8、 Network electricity price change function: When the electricity price changes, the new electricity price information can be transmitted to the meter through the 485 network.

9、 Malignant load control: When users use "malignant loads" such as electric heaters, electric stoves, and fast heating, the system automatically recognizes and cuts off power. After the malignant load is removed, the system automatically restores power supply.

10、 Load control: A limited current can be set for each household. When the electrical load exceeds this limit, the system will automatically shut down and restore power supply after the load is reduced.

11、 A minimum current can be set for each household. When the user's electricity current is below this limit, the system will no longer identify malicious loads, so that users can use low-power appliances with "malicious load" properties such as electric lights normally.

12、 Time period control: 12 time periods can be set, and the system automatically implements timed power on and off functions.

13、 Power outage alarm: Each household can set a power outage alarm level. When the user's remaining power reaches this set value, the household will automatically power off to remind them to purchase electricity in a timely manner. Users can restore power by pressing the button on the cabinet or swiping their IC card until the electricity is depleted and the meter is powered off again. Users need to purchase electricity before power can be restored.

14、 WeChat recharge. Users only need to bind their own room and dormitory number, follow the school's WeChat official account account, and then realize the functions of electricity query and recharge.
