Single Phase Multi-tariff Electronic Meter adopts advanced ASIC,
LCD, SMT technology
General introduction
1) Single Phase Multi-tariff Electronic Meter adopts advanced ASIC,
LCD, SMT technology with TOU or step tariff functions. It is
featured with high accuracy and reliabity, low power consumption,
long life, etc.
2 ) 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.
3 ) The communication has infrared and RS485 interface.

Main functions
It adopts wide viewing angle LCD with backlight and the meter can
be read and inquired with backlight. The displayed contents can be
switched via button, and the displayed items can be configured as
per the requirements.One kWh impulse isolated output and one kWh
impulse LED.
Import, export and total kWh metering, the total kWh can be
combined by import and export kWh.
4 tarifs; Built-in 2 sets of time zone tables. Calendar and clock
are available. It can set 8 time periods with minimum 15 minutes in
24 hours.
It 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.
It can measure various parameters such as voltage,
current(neutral), power, power factor, etc.
It can record programming, meter cover open, terminal cover open,
power outage, time correction with timestamp, etc.
- Meter can be read during power outage.
Q&A
Q1:What are the differences between smart energy meter and ordinary
energy meter?
A1:
1) 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. Besides, it is provided with
multiple functions, such as forward and reverse measurement, TOU
measurement, remote meter reading, remote monitoring and control,
electrical parameters measurement, security protection of consumed
energy information, event logs, etc.
2) Ordinary energy meter only has the energy metering
function.Compared with previous energy meters, smart energy meter
is added many new functions, such as measurement information
management, information management of energy consumed, monitoring
of energy quantities consumed, etc., which can better provide users
with accurate and timely billing function.
3) It has the bidirectional metering function and supports the
distributed energy utilization. In addition to recording the import
energy, it also can record the export energy. If the user is
self-built with distributed clean energy generation facilities,
such as wind energy, solar energy, etc., it can realize to transmit
the spare energy to power grid when the generated power cannot be
exhausted, thus achieve energy conservation and environmental
protection to reduce carbon dioxide emissions, create low carbon
life and improve the users' economic benefits.
