I-adaptha ye-AC ye-PC Material IP44 Outdoor Vertical Enclosure AC

Iyini i-adaptha yamandla?

Noma yimiphi imishini kagesi idinga i-adaptha yamandla e-dc ukuze ihlinzeke ngomsebenzi wesekethe, ikakhulukazi imikhiqizo kagesi eqhutshwa yi-adaptha yamandla egridi yamandla. Ukuze uzivumelanise nokuguquguquka kwe-voltage yegridi yamandla kanye noshintsho lwesimo sokusebenza sesekethe, kuyadingeka ukuthi ube ne-adaptha yamandla elawulwa yi-dc ukuze uzivumelanise noshintsho lwe-voltage yegridi yamandla kanye nomthwalo. Ukushintsha i-adaptha yamandla esilawuli se-voltage kwenziwa ngokushintsha i-dc ibe yi-pulse ephezulu yemvamisa, bese kuba ukuguqulwa kwe-electromagnetic ukuze kufezwe ukuguqulwa kwe-voltage kanye nokulawulwa kwe-voltage. I-adaptha yamandla esilawuli se-linear voltage ixhunywe ngqo ochungechungeni ngesici sokulungisa esingalawuleki ukuze kuhlukaniswe i-voltage ye-DC yokufaka ukuze kufezwe ukuguqulwa kwe-voltage kanye nokulawulwa kwe-voltage, okulingana kakhulu ne-resistor eguquguqukayo exhunywe ochungechungeni.

Ama-adaptha kagesi okulawula ukushintsha asebenza kahle futhi angakhuphula noma anciphise i-voltage. Ama-adaptha kagesi okulawulwa ngomugqa angagudluza kuphela futhi awasebenzi kahle. Ama-adaptha kagesi okulawulwa ukushintsha akhiqiza ukuphazamiseka kwemvamisa ephezulu, kuyilapho ama-adaptha kagesi okulawulwa ngomugqa engenakuphazamiseka. Ngayinye inezinzuzo nezinkinga zayo.

Eminyakeni yamuva nje, ngentuthuko yobuchwepheshe be-elekthronikhi kanye nocwaningo lwabantu mayelana nendlela yokuthuthukisa ukusebenza kahle kokuguqulwa kwe-adaptha yamandla ezinzile, ukuthuthukisa ukuzivumelanisa nezimo negridi yamandla, ukunciphisa usayizi nokunciphisa isisindo, i-adaptha yamandla yaqala ukuba khona. Ngawo-1970, i-adaptha yamandla isetshenziswa ku-receiver yethelevishini yasekhaya, manje isisetshenziswa kabanzi kuma-TV ombala, kuma-camcorder, kumakhompyutha, ezinhlelweni zokuxhumana, kumadivayisi ezokwelapha namathuluzi, embonini yezezulu nakwezinye izimboni, futhi kancane kancane yathatha indawo ye-adaptha yochungechunge lwamandla olulawulwa ngomugqa wendabuko, okwenza ukusebenza komshini wonke, ukusebenza kahle kanye nokuthembeka kuthuthukiswe kakhulu.

I-adaptha yamandla elawulwayo yochungechunge oluvamile ifakwe ne-transformer ye-adaptha yamandla, enezinzuzo ze-voltage yokukhipha ezinzile kanye ne-ripple encane, kodwa ububanzi be-voltage buncane futhi ukusebenza kahle kuphansi. I-voltage yokukhipha i-adaptha yamandla elawulwayo ehambisanayo izinzile kakhulu, kodwa umthamo womthwalo mubi, ngokuvamile usethuluzini lokubhekisela kuphela.
