Muaj ntau yam kev tiv thaiv Circuit Court ntawm PD fais fab adapter

Lub PD fais fab adapter hloov 220V AC lub zog rau hauv DC lub zog haum rau cov khoom siv hluav taws xob. Nws feem ntau yog tsim los ntawm vaj tse, transformers, inductors, capacitors, tswj ICs, PCB boards thiab lwm yam khoom. Nws yog dav siv nyob rau hauv lub xov tooj ntawm tes, laptops, koob yees duab, set-top boxes, thiab routers. thiab lwm yam khoom siv hluav taws xob. Vim tias nws txuas nrog 220V hluav taws xob hauv tsev, cov tuam ntxhab feem ntau teeb tsa plaub qhov kev tiv thaiv hluav taws xob tshaj plaws hauv Circuit Court kom muaj kev nyab xeeb thiab ruaj khov ntawm kev siv.
1. Kev tiv thaiv luv luv: Nrog kev tiv thaiv luv luv, lub hwj chim adapter tuaj yeem tiv taus qhov cuam tshuam ntawm qhov loj tam sim no los ntawm luv luv Circuit Court. Thaum qhov txhaum ploj lawm, lub adapter tuaj yeem rov qab los ntawm kev tiv thaiv hom thiab muab lub zog ntsuas dua.
2. Kev tiv thaiv overvoltage: Thaum lub voj raug puas, xws li optocoupler puas lossis TL431 voltage divider network cuam tshuam, lub adapter yuav tsum tsis txhob ua haujlwm tam sim ntawd thiab nyob twj ywm hauv lub xeev no kom txog thaum tus neeg siv rov pib lub adapter.
3. Kev tiv thaiv kub dhau: Thaum lub hwj chim adapter hloov 220V AC rau DC, ib feem ntawm lub hwj chim yuav raug siv thiab dissipated los ntawm huab cua nyob rau hauv daim ntawv ntawm tshav kub. Yog hais tias lub tshav kub yog lig dhau mus rau dissipate, thiab sau mus rau ib tug tej yam nqi, qhov kub thiab txias tshaj ib tug tej yam kub. tus nqi, lub adapter yuav raug puas tsuaj. Yog li ntawd, lub thermal sensor tau nruab rau hauv lub hwj huam hluav taws xob dav dav los saib xyuas qhov kub thiab txias, thiab thaum qhov kub siab tshaj qhov txwv tus nqi tsim los ntawm tus tsim, lub adapter yuav cia li kaw lub hwj chim. Thaum tus neeg siv hloov lub zog thiab qhov kub thiab txias, lub adapter rov pib dua.
4. Kev tiv thaiv hluav taws xob ntau dhau: Rau qee cov khoom siv hluav taws xob, nws yog ib qho tseem ceeb uas nyob rau hauv cov xwm txheej phem tshaj plaws - xws li cov khoom siv tam sim no los ntawm kev thauj khoom loj heev, qhov siab tshaj plaws tso zis tam sim no tau khaws cia rau hauv lub xeev tswj, thiab yuav tsis muaj qhov tseeb. luv Circuit Court, UE fais fab mov yuav ua tau.
