Ine-automatic voltage detector ezovikela isekethe, kungaba uma i-overvoltage noma i-undervoltage. Izovala ngokuzenzakalelayo ngokushesha nje lapho isekethe ibuyisela i-voltage evamile. Lesi yisisombululo esiphelele kakhulu sokuguquguquka kwesekethe yangempela, njengoba incane, futhi i-MCB ithembekile ngempela.

Imiyalelo ephaneli engaphambili

I-Auto:HW-MN izohlola i-voltage yomugqa ngendlela eqondile, futhi izokhubeka lapho i-voltage isiphelile noma ingaphansi kwe-voltage evamile.
