Product Description

Single Phase LCD Digital Display Lora Wireless Lorawan IoT Smart Electric Energy Meter for Energy Measurement



  • Product Overview
DDZY2397 single-phase charge control intelligent electric energy meter is a fully digital intelligent electric
energy meter developed by our company. Adopt SOC high integration chip. In addition to the active electric
energy metering function, it also has a variety of functions such as online power display, intelligent power
theft prevention, overload control, remote centralized meter reading, etc. The data is transmitted to the
corresponding platform through LoRaWAN/CAT1/Bluetooth wireless network. It has the characteristics of
high precision, low power consumption and good stability, and can be widely used in the measurement of
single-phase AC power in urban, rural or factory enterprises.
  • 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 LoRaWAN/Cat. 1/Bluetooth (optional) wireless network. The default interval is 4 hours

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.


  • Safety instructions

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.
