Product Description


Lorawan Wireless Three Phase Smart Electric Energy Power Meter LCD Display IoT Insulation Corrosion Resistance


  • Product Overview
DTZY2397 three-phase four wire charge control intelligent electric energy meter is a new generation of intelligent high-tech remote electric energy metering product. It is based on MCU+measurement chip technology. Large scale digital signal processing chip is adopted. It is designed and manufactured according to the relevant international (IEC) standards of electric energy meters and China's electric power standards. With LoRaWAN/CAT1/Bluetooth wireless communication modules, communication distance and networking problems are solved. It has the characteristics of high precision, low power consumption and good stability. An important part of the modernization of distribution management can be realized without complex cabling. It can be widely used in the measurement of three-phase AC power in cities, rural areas or factories and enterprises.
  • Highlights:
1. Metering positive active, negative active and ABC split phase active electric energy function. It can measure, store and display the ABC voltage, current, total and three-phase active power, total and threephase power factor, frequency and other operating parameters and status of the current watt hour meter. It has overload protection function.
2. 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.
3. Active upload/two-way transparent transmission function: actively transmit data to the corresponding platform through LoRaWAN wireless network. The default interval is 4 hours(settable).
4. Measurement and control unit (MCU) : Responsible for measuring electrical parameters (kWh, power, current, voltage, etc.).
  • Indicator display description:

​​• Trip indicator: yellow. Normally off closing state, normally on opening state.

• Active pulse indicator: red. It is off at ordinary times and flashes during metering.
• On-line indicator: green. If it is always on, it means that the module is online. Flashing indicates that the module is going online. Off              means not online.
