I-PC Material Direct Plug-in 18W 24W DC Adapter

Eyodwa, i-adaptha yamandla ekhompyutha ye-notebook ngaphandle kwesibonelo sokulungisa ukuphuma kwe-voltage

Ikhompyutha yamanothi, esetshenziswayo, ngenxa yezinkinga zolayini wokuphakela amandla ukuze i-voltage ikhuphuke ngokuzumayo, okuholele ekushisweni kwe-adaptha yamandla, akukho okukhipha amandla kagesi.

Inqubo yokulungisa: I-adaptha yamandla isebenzisa ukunikezwa kwamandla okushintshayo. I-voltage yokufaka isukela ku-100 iye ku-240V. Amandla kagesi angaphezu kuka-240V Angase ashise i-adaptha yamandla. Vula ikesi lepulasitiki le-adaptha yamandla futhi ubone ukuthi i-fuse iqhume, i-varistor ishile, futhi enye yezikhonkwane ishile. Sebenzisa i-multimeter ukukala isifunda sokuphakelwa kwamandla ngaphandle kwesenzakalo esisobala se-short-circuit. Faka esikhundleni i-fuse ne-varistor ngezicaciso ezifanayo, bese uxhuma i-adaptha yokuhlinzeka amandla. I-adaptha yokunikeza amandla isengasebenza ngokujwayelekile. Ngale ndlela, umjikelezo wamandla okuvikela ku-adaptha yamandla uphelele.

Kusukela ekuhlaziyweni kwesekethe kwangempela, i-varistor ne-bridge rectifier diode input input parallel, umsebenzi wayo uthi: ngesikhathi sokuhlasela kwamandla kagesi aphezulu, kusetshenziswa "i-fuse" yayo, ngaleyo ndlela ivikela ingxenye ye-adaptha yamandla yezinye izingxenye emonakalweni kagesi ophezulu.

Ngaphansi kwesimo se-voltage evamile engu-220V, uma ingekho i-varistor yokucaciswa okufanayo esandleni, ukusetshenziswa okuphuthumayo nakho akukwazi ukufaka ukumelana okwesikhashana.

Kodwa i-varistor kufanele ifakwe ngokushesha ngemva kokuthenga, ngaphandle kwalokho ikusasa alipheli, ukukhanya kuzoshisa izingxenye eziningi ku-adaptha yamandla, okungathí sina kuzoshisa i-laptop.

Ukuze ulungise igobolondo lepulasitiki elisusiwe le-adaptha yamandla, ungasebenzisa i-polyurethane adhesive ukuze unamathisele. Uma ingekho into enamathelayo ye-polyurethane, ungasebenzisa futhi itheyiphu kagesi emnyama ukugoqa imibuthano eminingana egobolondweni lepulasitiki le-adaptha yamandla.
