LoRaWAN Three-phase Smart Prepaid Energy Meter with Predictive Analytics and Real-time Monitoring
- 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 wireless network. The default interval is 4
hours(settable).
