900MHz smart prepaid electricity meter


RS232 smart prepaid electricity meter


900MHz 1 phase energy meter

Single Phase DLMS Smart Prepaid Electricity Meter IP54 PLC/RF/GPRS/3G and 4G LTE

This kind of electricity meter is single phase prepaid electricity meter. Single-phase electricity meter has the characteristics of high accuracy, accurate measurement, low maintenance workload, high work efficiency, low requirements for transportation and installation conditions, low power consumption, energy saving, good for reducing line loss, strong anti-power theft function, strong overload ability, low failure rate.The working principle is that when an alternating current passes through the voltage coil and current coil of a single-phase ww-hour meter, the voltage coil and current coil produce two alternating fluxes. These two alternating fluxes and the eddy current generated interact with each other to produce an electromagnetic torque, which pushes the aluminum disk to rotate.The greater the load power, the faster the speed of the aluminum disk.When the current transformer is equipped, the accuracy should not be less than 0.5 level.Single-phase watt-hour meter is applicable to commercial buildings and public infrastructure buildings to realize the measurement and statistics of electric energy consumption in different areas or different loads in buildings.Single-phase watt-hour meter is suitable for the statistics and internal accounting of electric energy consumption of different production lines or loads in industrial buildings.
Our electricity meter can carry GPRS communication module. GPRS module has many advantages, such as:
◆With short message function, support Chinese and English short message
◆ For GPRS data service, embedded TCP/IP protocol stack
◆ Support domain name resolution, can not be fixed IP
◆ Support MMS transceiver, can transfer pictures, files
◆ Standard RS-232 serial port, simple AT command operation
◆ Provide MCU and computer programming source code
◆ Dual frequency band 900MHz and 1800MHz
◆ Working temperature :-35~ +75℃
◆Industry standard design, can work in all kinds of harsh environment
◆Pieces of antenna interface 50 Ω / SMA (Yin)
◆ DC 5~12V power supply, standby current 40mA, transmission time 300mA
Moreover, this product belongs to the pre-paid electricity meter, which can help the supplier to manage the user's use of electricity and monitor the situation of electricity meter.It is convenient for suppliers to collect electricity charges and reduces the occurrence of users defaulting on electricity charges.Users can only use power if they pay in advance for the amount of power they need to use and enter TOKENS to recharge.
Our electricity meters can be topped up directly using the Stronpay vending software and can be topped up remotely via the LORA-RF and LORA-RF module communicating with the AMI system.AMI is Advanced Metering Infrastructure. AMI system is mainly composed of Smart Meter, communication system and equipment, Meter Database Management system, and Meter Database Management system.MDMS).

1. The electricity meter sends information to the Data Concentrator via LORA-RF or PLC;
2. The Data Concentrator contains Lora-RF/PLC and GPRS modules, which will transmit the information to the AMI through GPRS after receiving the information from the water meter.
3. The AMI receives the information, performs remote recharge, and will generate the recharge TOKEN.It is then sent to the Data Concentrator via GPRS;
4. Data Concentrator receives the information and sends it to the electricity meter via LORA-RF or PLC.
Basic Functionality

Function Details
Prepayment STS Standard, recharge by input 20digits TOKEN
Low credit alarm Alarm value can be set by inputting corresponding TOKEN
Prepaid and post-paid switch Meter can be switch to prepaid mode or post-paid mode
Load control function Meter can be programmed for load control threshold, If the current power is more than threshold. The meter will cut off user load.
Event recording Meter can record the tamper event, open cover event, purchase event and TOKENS.
Self-testing Meter has a self-test function, it can test LCD and relay etc. And report the results directly
Anti-tamper Meter will automatically close the valve after detection of magnetic field and open cover event
TOU Tariff TOU Tariff can be set by inputting corresponding TOKEN
Overdraft Collection Electricity Overdraft can be collected day by day or month by month
Communication The meter is available with AMI system through LORA RF or Bluetooth 4.0 on request
Information Inquiry Consumer could check the data like Credit Remain, Total Purchased and Total Credit by input the short code
