Product Description
LoRaWAN Three-phase Wireless Energy Meter for Advanced Energy Real-time Monitoring and Remote Control
- Product Overview
The DTZY2397 intelligent electricity meter has the functions of electric energy measurement, power parameter measurement, time-sharing measurement, real-time freezing, on-off control, LoRaWAN communication,etc.It is suitable for three-phase power consumption occasions.
- 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 wireless network. The default interval is 4 hours(settable).
