4、 Product Features

1. Prepaid function

The ADF400L series electric energy meter supports prepaid operation through remote or RF card. Users can recharge through IC card, and the meter automatically updates the remaining power. When the user's remaining power is insufficient, the system will issue a reminder and even automatically power off according to the settings to ensure electricity safety and cost management.

2. Multiple measurements

This meter can not only measure active and reactive energy, but also monitor parameters such as voltage, current, and power factor in real time. In addition, monitoring the total harmonic content and its sub harmonic content (2-31 times) is supported to help managers optimize the stability of the dormitory power system.

3. Load control

The ADF400L series electric meter supports overload power-off function. When the user's power exceeds the set value, the meter will automatically power off to avoid equipment damage due to overload. And the electricity meter also supports malignant load recognition, which can automatically cut off the power supply when abnormal electricity usage is detected, further improving electricity safety.

6、 Introduction to Acrel Prepaid System

Acrel prepaid system is a system solution mainly based on user side energy consumption measurement analysis and charging, as well as property inspection services. The whole solution includes terminal meter, edge computing gateway and system software developed and produced independently.

System Features

a. Project hosting, no on-site installation: The project site can save a series of work such as configuring prepaid servers and installing databases; Not only can it save a lot of hardware costs, but it can also greatly reduce debugging and maintenance costs.

b. Remote meter reading and remote electricity sales: Meter reading information is uploaded in real-time to the cloud platform through a gateway, which is fast and convenient, eliminating the need for manual meter reading; Centralized financial management, real-time issuance of electricity, and comparison of recharge times to prevent problems; Support one household one electricity price and one household one water price.

c. Cloud deployment, group style prepaid: System software upgrade and maintenance are no longer troubled by customer network environment, cloud unified deployment, easy and fast upgrade; The customer does not need to install the client.

d. Amount warning: Reminders for insufficient or overdue amounts, as well as reminders for meter recharge and receipt, can be promptly notified to merchants via SMS.

e. Remote control: It can perform a series of remote control and parameter setting operations, such as remote tripping or power protection, on any electricity meter for convenient management.

f. System scale: The access table is not limited by quantity or geography, and one account can manage multiple projects. The system design capacity exceeds 100000 measurement points.

g. Energy consumption analysis: Both users and administrators can query the daily energy consumption status of prepaid or control tables; We can provide an integrated comprehensive management report that combines energy consumption analysis and financial trajectory, including user table energy consumption, financial data, and initial and final values of energy consumption and finance.

h. Mobile APP, online payment: Owners can purchase electricity, water, and check energy consumption by logging into the mobile APP.

i. Unrestricted access method: The system will be able to access and make online payments through PC browsers, tablets, and mobile apps without human supervision.

j. Provide warm/cold/hot meter system module: The system can connect to cold/hot meters (warm/energy meters) for meter reading and provide corresponding reports

k. More scientific permission management: accounts are linked to projects, and the financial data of each property environment is independent of each other; Separation of role settings and account settings; Group headquarters users can access multiple projects.

l. Unified third-party API: Provides a unified third-party API or SDK development interface, and third-party platforms can choose to access or take over data.

m. Power station energy management: Provides remote automatic meter reading for substations, floors, and buildings, as well as related energy consumption analysis reports.

n. Prepaid Water Meter System: Provides all water sales related functions similar to prepaid electricity meters, automatically closing valves when the prepaid water volume is used up, such as remote water sales, water consumption reports, remote switch valves, etc., and integrates with the electricity meter as an integrated system.

o. Data security: AES encryption algorithm and key distribution mechanism are used for public network transmission to ensure data security.

p. Student dormitory environment: timed on-off control, malicious load control, basic free electricity, cost control, and mandatory control in the student dormitory environment.
