major function
Real time measurement of phase voltage, line voltage, current, active power, reactive power, apparent power, power factor, three-phase active power, three-phase reactive power, three-phase apparent power, three-phase power factor, frequency, etc.
● Supports dual energy accumulation, which means it can measure both conventional energy and rate energy. The former includes forward active energy, reverse active energy, forward reactive energy, reverse reactive energy, total active energy, and total reactive energy, respectively.
The latter includes forward active energy, reverse active energy, forward reactive energy, and reverse reactive energy.
● Statistics and recording of demand.
Measurement of power quality such as voltage imbalance, current imbalance, three-phase voltage harmonic content, three-phase current harmonic content, voltage odd, even distortion rate, current odd, even distortion rate, voltage peak coefficient, current K Factor, etc.
● Expandable external I/O module, which can be connected to 8 switch input modules (A), 4 switch input and 2 switch output modules (A), 6 analog input (voltage/current) modules (A), 2 switch output modules (B), 4 analog temperature acquisition modules (B), and 2 analog input (voltage/current) modules (B). The external module can be installed as any single module or any combination of an A-type module and a B-type module.
