- APFC (kVAR) -

Product Description

RTPFC is designed to compensate the reactive power on real time basis for extremely rapid acquisition of the power factor within the range of 40 – 60 msec. Connection and disconnection of the capacitor to and from the network occurs at zero crossing. This smooth connection avoids transient effects like waveform distortions, generation of switching spikes etc., typically created by electromechanically switched contactor based system. The response time of this is much higher than electromechanically switched systems.
