DDZY88C Single Phase Charge Control Smart Energy Meter
I.Overview:
The single-phase charge-control smart electric energy meter has a
measurement function that uses an independent measurement chip to
sample live and neutral currents at the same time. It has LCD
display, RS485, infrared communication and remote control power on
and off functions. The communication protocol of this electric
energy meter complies with DL/T 645—2007 multi-function electric
energy meter communication protocol.
The technology and specifications of this electric energy meter
meet the following standards:
DLT698.45 Object-oriented communication protocol
DLT698-2010 Electric Energy Information Collection and Management
System
Q/GDW 1354-2013 functional specification of smart energy meter
Q/GDW 1355-2013 single-phase smart energy meter type specification
Q/GDW 1364-2013 Technical Specification for Single-Phase Smart
Energy Meter
II. Main parameters:
1. Accuracy: Class 2.0
2. Rated voltage: 220V
3. Basic current: 1.5(6)A 5(30)A 5(60) A10(60)A 20(80)A.
4. Dimensions: 160mm×112mm×71mm
5. Installation size: 140 (150) mm×100mm
6. Basic error: meet the requirements of GB/T17215.321-2008.
7. Operating environment: The electric energy meter should be
installed in a dry and ventilated environment, the installation
height is 1.8 meters, the installation environment is free of
corrosive gas, the temperature is -40℃~+70℃, and the relative
humidity does not exceed 85%.
The main function:
1. It has the functions of forward and reverse active electric
energy and time-sharing measurement.
2. The clock adopts a built-in hardware clock circuit with
temperature compensation function, and has automatic conversion
functions for calendar, timekeeping, and leap year. In addition,
broadcast school time is not restricted by passwords and hardware
programming switches
3. Support 4 rates of sharp, peak, flat and valley.
4. It has the ability to clear the stored electric energy, freezing
amount, event record, load record and other data stored in the
electric energy meter.
5. It can store the two-way total electric energy and electric
energy data of various tariffs for 12 settlement days. In the case
of power failure of the electric energy meter, all data related to
settlement shall be kept for at least 10 years, and other data
shall be kept for at least 3 years.
6. It has functions such as timed freezing, instantaneous freezing,
daily freezing, agreed freezing, and hourly freezing. The frozen
content and identifier comply with the requirements of DL/T
645-2007 and its filing documents.
7. It can record the total number of power failures, the total
number of programming, the total number of time calibrations, the
total number of meter openings, and the permanent record of the
time of the electric energy meter clearing event and the electrical
energy data at the time of clearing.
8. With RS485 communication, infrared communication and other
functions, and all follow the DL/T 645-2007 protocol and its filing
documents.
9. It has the functions of electric energy pulse output and
multi-function signal output. 0
10. It has two display modes: automatic cycle and button.
11. The electric energy meter has the function of double protection
measures of programming switch and programming password
12. The realization of the cost control function is divided into
two ways: local and remote.
13. There are two sets of tiered tariffs, and another set of tiered
tariffs can be activated at the set point in time.
14. In the state of power failure, the display of the electric
energy meter can be awakened by pressing the button to facilitate
the reading of data.
15. When the electric energy meter performs parameter setting,
pre-stored electricity charges, information write-back and remote
control command operation for the electric energy meter through
solid or virtual media, it needs to pass strict password
verification or security certification such as ESAM module to
ensure the safety of data transmission reliable.
