Isigaba sesi-3 – Iqondwa kanjani incazelo “yebanga lefrikhwensi elinganiselwe”

Bygezhi-tech July 14, 2024September 27, 2025

ibanga lefrikhwensi elinganisiwe: ibanga lefrikhwensi elinikezwe umshini ngumkhiqizi, ovezwa imikhawulo yawo ephansi nangaphezulu.

Ngakho-ke, ngincoma ukuthi umake imvamisa elinganiselwe njengo-50/60Hz ngokuqondile.
Therefore, I recommend marking the rated frequency as 50/60Hz directly.
