Single Phase Smart Energy Meter with Operation voltage of 0.8un ~
1.2un
General introduction
Single Phase Smart Energy Meter with Operation voltage of 0.8un ~
1.2un can measure the import and the export active energy. It is with TOU
and step tariff function, and can be with PLC or RF module. It can
be controlled to disconnect and reconnect the load remotely.
Main functions
1. Display and indication: Large screen LCD, abundant graphics and
hinting text. The displayed contents can scroll automatically or be
trigged by button, and the displayed items can be configured as per
the requirements. It has 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 active energy 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.Moreover, the switching time for both 2 sets of time
zone tables and 2 sets of day profile table can be set and smoothly
switch. It can be set 14day profile and 254 holidays(special day).
4. Data snapshot: It supports various ways of freezing, which
include 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 and reconnection, reset of events, reset of
meter, etc.
6. Communication interface: The meter has one far infrared
interface, one RS485 and one PLC/RF(PLC and RF can be
interchangeable.)module interface. Interfaces are independent.
Communication protocol of meter conforms to DL/T645-2007.

AMI System advantages
1. Flexibility of configuration:
1.1 Function modularization: It can customize the equipment and
separately deploy the modules according to the size of the
management scale.
1.2 The function is hierarchically designed, which can guarantee
clear logic, convenient maintenance and the stable operation.
2. Diversity of management:
Managing range covers the different types of energy consumed
objects, such as Substations, Users with special transformer,
Distribution transformers, Residential Users, etc. It can configure
the relevant managing function according to the type of object.
3. Compatibility of equipments:
The users can choose the appropriate mode of network (such as GPRS,
PLC, WSN or 485), the collection equipments (such as various energy
meters or concentrators) and the operation protocol of equipments
according to their own situation. The system can provide support or
expansion.
