Okokuqala: jonga inkangeleko yetshaja yebhetri
Jonga inkangeleko yetshaja yebhetri, nokuba iqokobhe lomelele, nokuba intambo yamandla ijiyile
Okwesibini: jonga ukuba itshaja yebhetri iphumelele isiqinisekiso somgangatho
Jonga ukuba itshaja yebhetri inaso na isatifikethi somgangatho esifanelekileyo, esifana ne-UL, inombolo yokufaneleka yokuhlolwa ye-Quality Supervision Bureau, njl.njl. Jonga ukujonga ukuba ngaba zintathu iimveliso, igama lomenzi, iinkcukacha zoqhagamshelwano, kunye nomhla wokwenziwa kwesithuthi sombane. itshaja.Ukuba le miqathango idibene, ke le tshaja inokuthengwa ngokusisiseko ngokuzithemba.
Okwesithathu: khetha umenzi onamandla
Abavelisi betshaja yezithuthi zombane abaneminyaka emininzi yembali yemveliso bahlala benemiqondo yeshishini elingcono, kwaye inkonzo yabo emva kokuthengisa nayo iqinisekisiwe.Kwaye ngoku baninzi abavelisi be-OEM kwimarike abangavelisi iimveliso zabo, kwaye abakhathali nangomgangatho weemveliso zabo.Baxelisa nje ngobumfama baze benze umgunyathi, beqhayisa ngolwandle, yaye xa isantya sokubuya siphezulu, baya kutyibilika.Abathengi kunye nabathengisi banokuvuma ukuba baneshwa.Umzekelo ingaba unaso na isatifikethi somgangatho we-ISO 9001 okanye Cela umntu wesithathu ojonga indawo.
Njengetshaja elungileyo yebhetri, ukongeza kwiimfuno ezimbini ezisisiseko zokuxhathisa ubushushu obuphezulu kunye nokungavuzi, kufuneka ibe nale misebenzi ilandelayo:
Ukukhuselwa kwesiphaluka esifutshane, ukukhuselwa kwe-overcurrent, ukukhuselwa kwe-overvoltage, ukukhuselwa kwe-polarity reverse kunye nokukhusela okwesibini kokugqithiswa kwe-overvoltage
