Dual circuit IC card electric meter for school use-Fornitore globale

1st and 2nd floors, Office Area 106, Building 6, Hanlin Yujing, No. 9 Daxue East Road, Xixiangtang District, Nanning City

◆ Instructions for use

The school IC card dual circuit electricity meter uses radio frequency IC card as a medium to input various information into the smart meter. The smart meter automatically closes and supplies power according to the quantity purchased by the user. When the alarm value is reached or exhausted, the power will be automatically disconnected. Students need to purchase electricity again before they can use it. The school IC card dual circuit electricity meter has two live wire outlets, one of which is connected to the dormitory socket for power supply. This electrical device has functions such as power time control, maximum power control, and resistive load recognition. The other live line is connected to the dormitory's general lighting power supply. The school has implemented effective monitoring to avoid dangerous electricity usage and overspending, saving the management department's manpower, material resources, and financial resources, and improving management efficiency.

◆ System Function Implementation

1. Prepay electricity bills, trip for overdue payments, no need for meter reading and payment reminders.

Prepaid electricity fee with IC card, automatically trips and cuts off power when the prepaid electricity fee is exhausted or reaches the alarm value, without the need for meter reading and payment reminders.

2. Remaining battery display

The electronic display screen shows that students can observe the remaining and cumulative electricity consumption at any time through the electricity meter in this dormitory, making it clear at a glance.

3. Electricity consumption time control

The electricity meter is equipped with a built-in clock, which allows for the free setting of multiple power on and off time periods according to management needs, ensuring that students use electricity according to the school's requirements.

4. Resistive load safety control

The electricity meter is equipped with a load waveform automatic detection circuit. If a student uses a resistive load such as hot fast to disable the appliance, the electricity meter will automatically trip and cut off power.

5. Maximum load setting

The electricity meter can set the maximum load of the meter, and if it exceeds the limit, it will automatically trip without overloading, ensuring the safety of students' electricity use.

6. Dual circuit function

The live wire output of the electric meter is divided into two paths, one controlling the general lighting power circuit and the other controlling the socket power circuit. Time control only controls the electrical circuit of the socket to ensure that students have normal lighting and electricity at night.
