TimeWave 220V LoRaWAN Single-phase IoT smart wireless high accuracy energy meter DDZY2397
DDZY2397 single-phase IoT intelligent electric energy meter adopts
digital signal processing chip, permanent storage of information,
standard LoRaWAN communication interface, LCD and other
technologies. The advanced SMT surface mounting process is adopted
for the electric energy meter. The shell is made of high-strength, flame retardant and
environment-friendly materials, which is novel, beautiful and
applicable. It has high insulation strength and corrosion
resistance. The meter integrates many functions, including electric
energy metering, information storage and processing, information
interaction, etc.
1. Metering of positive and negative active electric energy. The electric energy shall be accumulated and stored separately for tip, peak, flat, valley and other periods and the total electric energy. It can store and display various electric quantities in the last 12 months. 2. It can measure, store and display the current voltage, current,
power, power factor, frequency and other operating parameters and
status of the electric energy meter. It has overload protection
function. 3. There are two sets of rates (tip, peak, flat and valley) and
time periods that can be programmed at will, and another set of
rates and time periods can be used at the set time point. At least
2 time zones can be set for each set of rate periods throughout the
year. At least 14 time periods can be set within 24 hours; The
minimum interval between periods is 15 minutes. The time period can
be set across zero points. 4. It has such freezing functions as instantaneous freezing,
regular freezing, daily freezing, agreed freezing, and hourly
freezing. 5. It has the functions of event recording such as zero clearing,
programming, timing, power failure, switching on and switching
off. 6. Remote power off and transmission function: send power off
command through RS485 and other communication interfaces to cut off
the user's load circuit. Or send the power transmission command to
connect the user load circuit. 7. Active upload/two-way transparent transmission function:
actively transmit data to the corresponding platform through
LoRaWANwireless network. The default interval is 4 hours
(settable).
The electric energy meter adopts LCD display. It can indicate the cumulative total electricity consumption and electricity consumption at various rates of the current and last January to last December. Status indicator lamp: The electricity meter uses a bright, long-life LED as a pulse
indicator light. It has active power pulse indicator light: red, usually go out,
flashing when measuring active power. LoRaWAN/Cat.1 Module status indicator: green. Always on indicates
online, and flashing indicates going online.
Among them, 5 and 6 are reactive pulse output (empty). 7 and 8 are
active pulse output. 9 and 10 are clocks. 11 and 12 are RS485. Live installation of wiring is strictly prohibited! The electricity meter shall be installed indoors as far as
possible. Special instrument box protection shall be used for
outdoor installation. The installation bottom plate shall be fixed
on the wall with strong fire resistance and not easy to vibration.
There must be no corrosive gases in the surrounding air where the
meter is installed. Avoid dust, salt spray, etc. When using the electricity meter, the wiring must be conducted
strictly according to the wiring diagram in the tail cover of the
meter. It is recommended to use copper wire for the lead connected
to the terminal seat. The screws of the fixed lead in the terminal
seat should be tightened to avoid burning the electricity meter due
to bad contact and heating.
Ammeters must be transported and stored under the original packaging conditions. Products shall not be severely impacted during transportation and unpacking, and shall be transported and stored according to GB / T 25480-2010 Basic Environmental Conditions for Instrument Transportation and Storage and Test Methods as stipulated in 2010. The products should be stored in the warehouse and placed on the platform frame. The stacking height shall not exceed five layers. No corrosive gases shall be present in the stored environment.
If the user complies with the transportation, storage and
installation operation specifications, and the lead seal of the
manufacturer is still complete.If there is a quality problem, our
company is responsible for free repair or replacement within 18
months from the date of delivery the electricity meter. |
