50/60Hz Single Phase AMI Smart Energy Meter
General introduction
50/60Hz Single Phase AMI Smart Energy Meter can measure the import and the export active energy,and is with TOU
and step tariff functions, and can be with PLC or RF module for
communication, and can be controlled to disconnect or reconnect the
load remotely.
Main functions
1. Display and indication: It adopts a large screen LCD with abundant graphics and hint text. The displayed contents can be scrolled automatically or by button, and the displayed items can be configured as per the requirements. It is with backlight. Meter can be read during power outage.
2. Metering and measurements: It can measure the import and the export active energy and the total active energy. The total active energy can be configured by the import and the export active energy as per the requirements. It can measure voltage, current, power, power factor, neutral current(optional), etc.
3. TOU:4 tariffs; Built-in 2 sets of time zone tables and 2 sets of
daily period tables, which can be configured as per the
requirements. The switching time for both 2 sets of time zone
tables and 2 sets of daily period tables can be set and achieve the
mutual switching. It can set 14 time intervals and 254 holidays.
4. Data Snapshot: It supports freezing which includes daily freezing,hourly freezing, occasional freezing, immediate freezing.
5. Event logs: It can separately record latest 10 times events, such as power outage, programming, time correction, meter cover open,disconnection/re-connection, reset of events, reset of meter, etc.
6. Communication interface: The meter has one far infrared
communication interface, one RS-485 communication interface and one
PLC/RF (PLC and RF can be changeable.) communication module
interface. Interfaces are independent with each other. The protocol of meter
conforms to DL/T645-2007.
