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.

Bygezhi-tech July 17, 2024September 27, 2025

ukusebenza okukude: ukulawulwa kwento esetshenziswayo ngomyalo ongaqalwa endaweni engabonakali kusetshenziswa izindlela ezifana nezokuxhumana, izilawuli zomsindo noma amasistimu amabhasi.QAPHELA Ukulawula okubomvu kwe-infra-red ngokwako akubhekwa njengokusetshenziselwa ukusebenza kwerimothi. Kodwa-ke, ingahle ifakwe njengengxenye yesistimu efana nokuxhumana ngocingo, isilawuli somsindo noma isistimu yebhasi. Kusuka kokuqukethwe kombhalo kulula ukuqonda incazelo yalesi sigatshana, lapha uhlelo lwezokuxhumana ngokuvamile lubhekisela ocingweni, kuphela kusukela…
