Transformer ea 12V hangata ke sesebelisoa sa AC. Ka kutloisiso e thata ea motlakase, transformer e sebetsa ka motlakase o feto-fetohang mme e fetola motlakase oa AC ho tloha boemong bo bong ho ea ho bo bong. Mohlala, transfoma ea khale ea 12V e ka hata 120V AC, 230V AC, kapa tlhahiso e 'ngoe ea AC ho theohela ho 12V AC.
Leha ho le joalo, batho ba bangata ba sebelisa lentsoe "transformer" ka mokhoa o sa reroang ho hlalosa sesebelisoa leha e le sefe se fetolang matla a maholo hore e be tlhahiso ea 12V. Sena se ka baka pherekano. Haeba tlhahiso e le 12V DC, sesebelisoa ha se feela transformer. Hangata ke phepelo ea motlakase, adaptara, mokhanni, kapa converter e kenyelletsang tokiso le taolo. Ke ka lebaka lena sehlahisoa se hlalosoang e le a 12v dc transformer e lokela ho hlahlojoa ka hloko ho netefatsa hore na e hlahisa AC kapa DC.
Ha e le hantle, Transformer e Etsa'ng?
Transformer e fetisetsa matla a motlakase lipakeng tsa mapheo a mabeli ka ho kenella ka motlakase. E ka theola voltage, ea nyolla voltage, kapa ea fana ka ho itšehla thajana lipakeng tsa li-circuits.
