LoRaWAN Single-phase Smart Prepaid Energy Meter with Predictive Analytics and Real-time Monitoring
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 the functions of event recording such as zero clearing, programming, timing, power failure, switching on and switching off.
5. 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.
6. 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).
