Product Description

TimeWave 220V LoRaWAN Single-phase IoT smart wireless high accuracy energy meter DDZY2397


  • Product Overview
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.
  • Functions and features

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).

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.
