basic function
The AMR-C9C series intelligent digital electric meter has a complete power parameter measurement function, providing real-time measurement of the following data:
Voltage V: three-phase phase voltage, line voltage, and their average values
■ Current I: three-phase line current and its average value, neutral line current
■ Active power P: active power of each phase in the four quadrants and active power of the system
Reactive power Q: Reactive power of each phase in the four quadrants and reactive power of the system. The calculation method for reactive power can be selected; Generalized reactive power or narrow reactive power
■ Apparent power S: apparent power of each phase and apparent power of the system
Power factor PF: power factor of each phase and system power factor
Frequency F: When a voltage signal is present, the frequency of the system can be measured
■ Load property indication
■ Load percentage display
■ Four quadrant power display

Power quality parameters
The AMR-C9C series intelligent digital electric meter can monitor the 2-31st harmonic components of three-phase systems in real time and calculate various power quality parameters, making it very suitable for applications that are sensitive to power quality. All power quality parameters can be read from the panel or communication.
