Overview:
Three-phase intelligent power meter is a kind of high precision measuring instrument which integrates measurement, monitoring, LCD display and digital communication. It can bewidely used in multiple scenarios and fields, such as intelligent buildings,power systems, low-voltage distribution, industrial automation, energy management systems and automation.
Features:
The real-time measurement of current, phase and line voltage,active reactive and apparent power, power factor, frequency, angle, load characteristic.
LCD display shows three-phase voltage, current, power, frequencyand other electrical parameters display, active and reactive energy display.
2-31 harmonics measurement of each phase voltage /current.
RS485 communication interface for data exchange.
The communication rate of the RS485 can be set in 1200bps,2400bps, 4800bps, 9600bps, and the default rate is 9600bps..

LCD Display Screen: The electric meter uses digital backlight LCD display which shows three-phase voltage, current, power, frequency and other electrical parameters display, active and reactive energy display.
RS485 Communication: With a RS485 communication interface to host computer for data exchange, the digital power meter comply with the Modbus-RTU protocols, the terminals are marked A and B.
Real Time Alarm: The three-phase power meter can do real-time alarm of loss of press, over-voltage, under-voltage, phase failure, loss of flow, over-current, current cutoff, overload and so on.
Harmonic Measurement: Intelligent Power Meter can measure 3-37 harmonics of each phase voltage /current(graded harmonic content, total distortion rate, odd total distortion rate, even total distortion rate).
Compound rate energy：Time-sharing active, reactive, and apparent energy metering functions, accumulating, storing total, sharp, peak, flat, and valley energy according to the corresponding time period，And the electric energy meter has two sets of time zone tables and two sets of daily timetables.
