Technology Microcontroller based intelligent PF Controller Microcontroller based intelligent PF Controller
Measurement True RMS measurement – Operates reliably even under high harmonics load
Assuming balanced load conditions, it measures voltage and current on
true rms basis of one of the phases and computes the power factor
