• 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 2-31 harmonics of each phase voltage /current(graded harmonic content, total distortion rate, odd total distortion rate, even total distortion rate).
• Wide Applications: This meter is applicable to campus dormitories and large-scale of electrical energy metering, can also be used in enterprises and institutions for power management assessment.
