Main functions
- UIU communication interface: PLC, RF or twist-wire is optional.
- Friendly power supply: Support emergency credit.
- Events logs: Detecting and recording events such as current reverse, magnetic
influence, phase bypass, meter cover open, terminal cover open,
overvoltage, under voltage, etc.

the load when verload.
- Communication interface: Optical port and RS485 interface are available.
- Step tariffs
- TOU: Four tariffs; two sets of time zone tables; two sets of time
period tables; support public holidays and weekends
Q&A
Q1: What are the differences between smart energy meter and
ordinary energy meter?
Q1: What are the differences between smart energy meter and
ordinary energy meter?
A1:
1) Ordinary energy meter only has the energy metering function.
Smart energy meter is added many new functions, such as measurement
information management, information management of energy consumed,
monitoring of energy quantities consumed, etc.
2) Smart energy meter has the bidirectional metering function and supports the
distributed energy utilization. It can record the export and the
import 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.
Q2: What is the smart energy meter?
A2: As a new-type energy meter, It adopts digital metering
technology, consists of measuring unit, data processing unit,
communication unit, etc.And 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.
