Certification:
STS
Model Number:
STE18-A
Our STE18-A is an STS Standard compliant, keypad type, automatically connection or disconnection prepaid smart electricity meter. It can be top up with Stronpay vending software directly and communicate with AMI system via LORA-RF or PLC module.
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).
How to recharge by AMI System? As shown in the figure below:
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.
