Notification 636 -– Device current limit exceeded

FIX / REFERENCE(S)

Information

Peak primary current exceeds device current limit. This may cause degradation of Power Factor and Harmonics.  

  • Select larger PI device or lower KP (if applicable).  

 

If the current limit is exceeded the current near the top of the voltage waveform will have a nearly flat top, which will increase the individual harmonic content, and degrade power factor.
