Ingcaciso yeMveliso

Ikhusela kwi-voltage engaphezulu nangaphantsi kwe-voltage kuyo nayiphi na i-phase kwezi zintathu kunye nokulahleka kwe-phase enye okanye ezingaphezulu. Ukuqhawuka ngenxa yempazamo yefrikhwensi ye-mains okanye impazamo ye-phase sequence iyafumaneka njengokhetho.

Ngokungafaniyo ne-AVS303, I-AVS3P-0 yenzelwe ukusebenzisa isekethe yokulawula yangaphandle okanye i-contactor enokuba yinxalenye yesiqalo semoto okanye ezinye izixhobo. I-AVS3P-0 inomnxibelelwano wokutshintsha ongena-volt njengesiphumo.
