Yuav ua li cas paub qhov txawv ntawm LED switching fais fab mov yog qhov tam sim no thiab qhov hluav taws xob tas li?
Peb tau txais cov khoom siv hluav taws xob hloov hluav taws xob los txiav txim seb nws puas yog qhov chaw tam sim no lossis qhov hluav taws xob tsis tu ncua, peb tuaj yeem saib ua ntej ntawm cov khoom siv hluav taws xob hloov hluav taws xob, feem ntau hauv cov khoom siv hluav taws xob hloov hluav taws xob saum lub logo, feem ntau hloov hluav taws xob los ntawm cov khoom siv. hwj chim, voltage, tam sim no thiab tso zis hwj chim, voltage, tam sim no thiab lwm yam coj tsis tau, tab sis kuj nyob rau hauv lub hwj chim mov ntawm lub cim tsis tu ncua voltage los yog tas li tam sim no.
Yog hais tias nyob rau hauv lub tswv yim daim ntawv thov ntawm lub logo saum toj no tsis pom yuav ua li cas peb paub qhov txawv ntawm lub hwj chim mov yog ib tug tsis tu ncua voltage qhov chaw los yog tas li tam sim no qhov chaw, peb muaj peev xwm ntsuas tau, peb coj lub lag luam saum toj no 60W12V5A fais fab mov ua piv txwv, yog hais tias qhov chaw yog qhov tam sim no tsis tu ncua, peb ntxiv 120W load ntawm qhov tso zis ntawm cov khoom siv hluav taws xob, lub sijhawm no, nws cov zis peb ntsuas qhov tam sim no tseem yog 5A, tab sis nws qhov hluav taws xob yuav poob mus rau 6V, yog tias peb thauj khoom lub sijhawm no rau 30W, cov zis tam sim no yog 5A, nws cov zis hluav taws xob yog 24V, peb cov khoom siv hluav taws xob hloov pauv yuav nrog kev hloov pauv ntawm qhov hloov pauv tam sim no, yog tias nws yog qhov hluav taws xob tas li yog nrog kev hloov ntawm lub load, qhov voltage tsis hloov. , thaum tam sim no hloov.
Yog li yuav ua li cas hloov lub zog hluav taws xob ua tiav qhov hluav taws xob tsis tu ncua thiab tsis tu ncua tam sim no? Qhov tseeb, qhov no yuav tsum tau ua nrog rau hauv Circuit Court nyob rau hauv lub sampling tawm tswv yim Circuit Court, yog hais tias lub switching transformer yog ib tug tas mus li tam sim no, ces lub sampling Circuit Court nyob rau hauv lub switching fais fab mov yuav tsum tau sampling tam sim no, yog hais tias lub switching fais fab mov yog ib tug tas mus li tam sim no, ces tus qauv Circuit Court nyob rau hauv lub switching fais fab mov yuav tsum yog sampling tam sim no. cov zis sampling feem ntau yog sampling voltage.
Tam sim no feem ntau ntawm cov khoom siv hluav taws xob yog cov khoom siv hluav taws xob tas li, qhov hluav taws xob tsis tu ncua tam sim no kuj tsawg dua, peb xaiv hom kev hloov hluav taws xob li cas raws li qhov tshwj xeeb Circuit Court los txheeb xyuas thiab sab nraub qaum ntawm qhov yuav tsum tau nqa lub load los txiav txim. Cov kev xav tau ntawm high voltage ntawm qhov kev xaiv ntawm qhov tsis tu ncua voltage, qhov siab tam sim no yuav tsum tau xaiv ntawm qhov tam sim no qhov chaw.
