35mm DIN standard installation complying single phase meter with
DIN EN-5002
General introduction
The meter can exchange information based on TOKEN complying with
STS, it can be charged through network or button, the meter will
automatically disconnect the load when the credit is low and detect
the abnormal circuit; It adopts DIN RAIL standard, with features of
easy installation, small size and light weight.
Main Function

RS801E AMI System General
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.
