Single Phase Smart Meter with PLC/RF Module
General Introduction
Single Phase Smart Meter with PLC/RF Module can measure the import
and the export active energy, and is with TOU and step function,
and can be with PLC or RF module for communication, and can be
controlled to disconnect and reconnect the load remotely, which
conforms to DLMS/COSEM.
Main functions
1. Display and indication: It is with the wide viewing angle LCD
for displaying, which has backlight and can display the status
indication and the hint characters. The displayed contents can be
switched via push button, and the displayed items can be configured
via communication. It is with one kWh impulse isolation output, one
LED for kWh impulse; one LED for relay ON/OFF, and one LED for
alarm.
2. Measurement: It can measure the import active and the export
active energy and the total active energy. The total active energy
can be selectively combined by the import and the export active
energy.
3. TOU:4 tariffs; Built-in 2 sets of time zone tables and 2 sets of
daily period tables, which can be set as per the requirements.
Moreover, the switching time for both 2 sets of time zone tables
and 2 sets of daily period tables can be set, and the main and
backup switching can be configured. It can be set 8 time intervals
within 24 hours, and 100 holidays.
4. Billing: It can be set 20 billing points per month. It can
maximally record latest 12 times' billing historical data including
import and export active energy of each tariff.
5. Measurements: It measures various parameters, such as voltage.
current(neutral optional), active power, power factor, etc.
6. Event logs: It records the status of meter and the timestamp of
events, such as programming, opening of meter cover, power outage,
time correction, disconnection/reconnection, etc.
7. Remote disconnection and reconnection of the meter
8. Communication interface: Independent RS485/RS232, PLC/RF,
Optical port.
9. Load profile: at least for 40 days with the time interval of 15
minutes.
10. Alarm: The meter will alarm when the meter cover is opened or
the tamper event is happened.
11. Meter reading at power outage: Meter registers can be read via
button or optical port.
12. Communication interface: The meter has one infrared interface,
one RS-485 and one PLC or RF interface. Interfaces are independent.
The protocol of meter conforms to DLMS/COSEM.

Q & A
Q1: What is the smart energy meter? What are the functions of smart
energy meter?
A1: As a new-type energy meter, smart energy meter adopts digital
metering technology, consists of measuring unit, data processing
unit, communication unit, etc., and has various functions such as
energy metering, data processing, real time monitoring, automatic
control, information exchange, etc.
In addition to the above functions, smart energy meter also
supports various actual requirements, such as bidirectional
metering, step tariff, TOU tariff, peak-valley tariff, etc. It’s
also the technology base to achieve distributed power measurement,
two-way interactive service, smart home and intelligent community.
