With the rapid development of the national economy, the operating conditions of major colleges and universities in China have also been greatly improved. The conditions and grades of student apartments have been fundamentally improved. Various electrical equipment such as air conditioning, electric heating equipment, and computers have already entered student apartments, causing a rapid increase in electricity load and posing great challenges to electricity safety and traditional electricity management models. Prepaid electricity meters for student apartments are designed for the management of electricity consumption by college students, facilitating safe electricity management in student apartments. The meters developed by our company for student apartments can distinguish between inductive and resistive loads based on their characteristics. When the electrical appliances reach the set value of the meter, the meter itself automatically shuts off, effectively avoiding the occurrence of fires.

● Functional features

※ Prepaid function:

Purchase electricity first, use electricity later, and automatically cut off power without charge. When the remaining electricity on the user's meter reaches the set value, the meter will automatically cut off power until payment is made again and the meter will automatically restore power supply;

※ Power outage alarm:

When the user's remaining power reaches the system set value, the user will automatically power off to remind them to purchase electricity in a timely manner.

※ Dual battery display function:

During the electricity consumption process, users can view parameters such as remaining power on the meter or visually display them through the 485 network administrator terminal;

※ Malignant load control:

When users overload high-power electrical equipment, the system automatically recognizes and shuts off the power. When the load returns to normal, the system automatically resumes power supply.

※ Time period control:

Multiple time periods can be set daily (up to 8 time periods), and the system automatically implements timed power-off and power on functions.

※ Overcurrent protection function:

When the electricity consumption of a household exceeds the system set value, the electricity meter will automatically shut down to protect the meter and electrical appliances.

※ Dual loop control (optional):

For the same user, dual circuit power supply is used, with one circuit for identifying malicious loads and the other circuit being uncontrolled.

※ Free basic electricity (electricity subsidy) setting:

The system can provide students with a unified free electricity gift on a monthly basis;

※ Refund Management:

When students graduate, the system operator can print out a detailed list of all electricity meter refunds and refund fees upon account cancellation;
