Product Description
Three Phase LCD Digital Display Lora Wireless Lorawan IoT Smart Electric Energy Meter for Energy Measurement
- 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.
- Functions and features
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 three phase 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/CAT1/Bluetooth (optional) wireless network. The default interval is 4 hours (settable).

- Installation
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.
