DDSF217 Single Phase Multi-tariff Electronic Meter

General introduction

1) DDSF217 Single Phase Multi-tariff Electronic Meter adopts advanced ASIC, LCD, SMT technology with TOU or step tariff functions.

2) It is featured with high accuracy and reliabity, low power consumption, long life, etc.

3)The Billing can record latest 12 time's billing historical data including total kWh and kWh of each tariff. If billing time is missed during a power outage,all billing data will be supplemented with latest 12 times when the power is on.

4 ) The communication has infrared and RS485 interface.

Q&A

Q: What is the AMI System ?

A: Advanced Metering Infrastructure (AMI) is the technology of automatically collecting data from energy metering devices and transferring that data to a central database by communication technology for remote control and analyzing. RS801E AMI system is composed of management software, remote communication channel, power management terminal, regional summary meter, local communication channel, user energy meter and other equipments. Power companies can build AMI system to replace the manual meter reading to save human resources, reduce meter reading costs and improve meter reading efficiency and success rate. The AMI system reduces the error rate, the electricity loss and eliminates the false meter reading by personnel. The AMI system also can monitor the status of the users and find the abnormal information to alarm in time. It also collects data from regional summary meter and the regional line loss can be calculated. The software system is developed by Java and it can be deployed on Windows, Unix, and other major operating systems. The system is developed based on Enterprise-class Jave EE standards, a three-tier technical architecture (client / middleware server / database server) as the basis for the system. The system has excellent openness, scalability, flexibility and high reliability. Many advanced computer and communication technologies are used on this AMI system to satisfy the needs of power companies in different environments.
