Peb paub tias raws li kev hloov pauv hluav taws xob, nws cov khoom siv hluav taws xob optocoupler tau txais los ntawm qhov hluav taws xob thib ob ntawm lub tshuab hluav taws xob ntau zaus, thaum cov zis hluav taws xob raug txo qis rau ntau yam laj thawj, cov lus tawm tswv yim tam sim no yuav raug nce ntxiv, lub voj voog lub luag haujlwm tseem yuav. ua correspondingly loj, qhov tshwm sim ua rau cov zis voltage nce; Yog hais tias qhov tso zis voltage nce, ces tam sim no yuav ua me me, lub luag hauj lwm voj voog kuj yuav raug txo, ua rau cov zis voltage qis.
Thaum lub sij hawm nruab nrab ntawm lub siab zaus transformer yog overloaded los yog lub switching Circuit Court yog faulty, tsis muaj optocoupler fais fab mov, lub sij hawm no lub optocoupler tswj lub switching Circuit Court tsis tau pib, thiab nws thiaj li tiv thaiv lub hloov raj los ntawm raug hlawv los ntawm kev puas tsuaj. , yog li lub optocoupler nyob rau hauv lub switching fais fab mov feem ntau plays lub luag hauj lwm nyob rau hauv kev sib cais, muab cov lus qhia tawm tswv yim thiab hloov peb.
Cov duab hauv qab no yog kev sib txuas ntawm photocoupler PC817 thiab voltage regulator switching power supply circuit, ib co switching power supplys kuj yuav nrog TL431 los ua ib tug ntau dua precision Circuit Court. Nco ntsoov tias qhov optocoupler no feem ntau yog linear optocoupler.
Optocoupler muaj ib txoj kev kis tau tus mob, thiab cov kev tawm tswv yim thiab cov zis kom ua tiav cov hluav taws xob sib cais, kom cov teeb liab tso zis tsis cuam tshuam rau cov tswv yim, yog li nws yog dav siv nyob rau hauv ntau yam kev sib cais circuits, rau lub hwj chim electronics, nyob rau hauv AC load. daim ntawv thov yog ntau, los ntawm cov muaj pes tsawg leeg ntawm ib tug muaj zog tiv thaiv kev cuam tshuam muaj peev xwm cais Circuit Court ua ke nrog thyristor, raws li nram no, nco ntsoov hais tias kom nce lub tam sim no limiting resistor, ntxiv rau cov zis load kom lub RC absorption Circuit Court los yog thaum uas tig mus ib tug varistor, uas pab tiv thaiv lub nra.
Yuav kom ua tiav tshaj xoom qhov tseeb, muaj ntau txoj hauv kev, muaj ob txoj hauv kev diode hauv series, tab sis kuj los ntawm optocoupler los hloov, raws li hauv qab no.
Kev siv ob lub optocouplers, AC inputs, ob optocouplers nyob rau hauv lub rov qab parallel, nyob rau hauv qhov zoo thiab tsis zoo ib nrab ntawm cov nqi hluav taws xob ob optocouplers yog nyob rau hauv lem, thaum lub nqi hluav taws xob tsis nyob rau hauv lub over-zero point, tsuas yog ib tug optocoupler rau, cov zis. qib qis, thaum lub nqi hluav taws xob tig mus rau qhov chaw tshaj xoom, ob lub optocouplers tsis nyob, lub sijhawm no vim yog lub luag haujlwm ntawm R3, tus pin tso zis siab, yog li lub sijhawm ntawm qhov tso zis kom tau txais cov teeb liab mem tes ntawm 10ms. Txij li thaum lub Circuit Court no yog cais los ntawm lub luag hauj lwm ntawm lub optocoupler, yog li no over-zero detection Circuit Court muaj kev ruaj ntseg ntau tshaj li hom Circuit Court nrog series diodes.
Ntxiv rau peb qhov no, muaj lwm yam kev siv ntawm optocouplers, xws li trigger circuits, logic circuits, mem tes amplification circuits, thiab lwm yam.
Zhejiang NeoDen Technology Co., Ltd. tau raug tsim thiab xa tawm ntau yam me mexaiv thiab tso cov tshuabtxij li xyoo 2010. Ua kom zoo dua ntawm peb tus kheej nplua nuj kev paub R&D, kev cob qhia zoo, NeoDen yeej lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.
Nrog lub ntiaj teb muaj nyob hauv ntau dua 130 lub teb chaws, kev ua tau zoo heev, qhov tseeb thiab kev ntseeg siab ntawm NeoDen PNP cov cav tov ua rau lawv zoo meej rau R& D, kev tshaj lij prototyping thiab me me rau nruab nrab batch ntau lawm. Peb muab kev daws teeb meem ntawm ib qho khoom siv SMT nres.
Hauv peb lub ntiaj teb Ecosystem, peb koom tes nrog peb cov neeg koom tes zoo tshaj plaws kom xa cov kev pab cuam muag khoom ntau dua, kev ua haujlwm siab thiab kev txhawb nqa zoo.
Peb ntseeg hais tias cov neeg zoo thiab cov neeg koom tes ua rau NeoDen yog ib lub tuam txhab zoo thiab tias peb txoj kev cog lus rau Innovation, Diversity thiab Sustainability kom ntseeg tau tias SMT automation yog nkag tau rau txhua tus neeg nyiam nyiam nyob txhua qhov chaw.
