Measures forward and reverse active energy with accumulation for peak, flat, and valley time periods. Stores power data for previous 12 months.
Monitors voltage, current, power, power factor, frequency, and provides overload protection.
Two sets of rates (sharp, peak, flat, valley) with programmable time periods, supporting 14 time periods within 24 hours.
Remote disconnection and power transmission via RS485 communication interface for load management.
LoRaWAN connectivity for active data upload to platforms with default 4-hour intervals (configurable).
Automatic meter calibration after power-on and LoRaWAN network connection.
The meter features a comprehensive LCD display showing current consumption, previous month data, 12-month cumulative totals, and rate-specific electricity usage. Status indicators provide real-time feedback on communication, reverse power, programming status, and relay state.
Designed for indoor installation with IP54 protection rating. Outdoor installation requires special instrument box protection. Strict wiring procedures must be followed according to the provided diagrams.
18-month warranty from delivery date with comprehensive after-sales service including technical documentation, maintenance training, and software updates. Service response within 12 hours of request.
