2 tus pin fais fab qaum nrog VDE ntawv pov thawj Txheej txheem cej luam
2 tus pin fais fab qaum nrog VDE ntawv pov thawjpaub txog nws qhov kev ua tau zoo tshaj plaws. Lub ntsaws ntawm lub computer 2 tus pin fais fab qaum yog cim nrog cov xim kom ntxaws heev. Tshwj xeeb, liab yog +5 V, daj yog +12 V, dub yog "txias" hlau (hauv av).
Tsis tas li ntawd, koj tuaj yeem siv tus pin no los ntsaws rau cov kiv cua txias ntxiv thiab lwm yam khoom siv xws li daim npav duab. Motherboard: Feem ntau suav nrog 20-24 pins nyob ntawm koj lub motherboard. Lwm version ntawm lub ntsaws no yog 20 + 4 pins (pairing 20-pin thiab 4-pin connector ua ke.
2 tus pin fais fab qaum nrog VDE ntawv pov thawjsiv fais fab txuas thiab plugs. Fais fab connector rau central processing unit (CPU) (+ 12V fais fab txuas: Muaj ob hom; plaub-pin thiab yim-pin (feem ntau plaub-pin, qhov chaw tshiab tsim los rau cov laus motherboards). :
1. Yog li Plug rau hard drive, optical drive (ATA interface) (Peripheral connector): suav nrog 4 tus pins.
2. Plug rau floppy drive: suav nrog 4 tus pins.
3. Plug rau hard drive, optical drive nrog SATA interface: suav nrog 4 xov hlau.
4. Plugs rau high-end graphics phaib: suav nrog 6 tus pins.
Qee yam uas koj yuav tsum paub thaum siv 2 tus pin fais fab qaum
Hauv qab no yog qee yam ntawm cov xwm txheej; uas yuav tsum koom nrog2 tus pin fais fab qaum nrog VDE ntawv pov thawj
Tuav lub sij hawm
Lub sij hawm tuav tus nqi txhais tau tias ntev npaum li cas, hauv milliseconds, 2 tus pin fais fab qaum tuaj yeem tuav cov kab tso zis thaum lub zog tawm tswv yim raug txiav tawm (piv txwv li, lub zog tsis ua haujlwm). Ib yam li ntawd, qhov no tseem ceeb heev tshwj xeeb tshaj yog thaum koj nyob hauv thaj chaw uas tsis muaj hluav taws xob tsis ruaj khov
(Piv txwv li, thaum lub hwj chim dheev flashes thiab rov qab los, lub computer tseem tuaj yeem ua haujlwm ib txwm). Lub sij hawm tuav tus nqi ntawm ATX tus qauv yog 17ms thiab lub khoos phis tawj 2 tus pin fais fab qaum yuav tsum muaj qhov ntsuas no siab li qhov ua tau.
Power Factor Correction (PFC) hauv 2 tus pin fais fab qaum nrog VDE ntawv pov thawj
PFC tso cai rau 2 tus pin fais fab qaum kom ua haujlwm tau zoo. Muaj ob hom PFCs tseem ceeb: Active PFC thiab Passive PFC. Tsis tas li ntawd, cov neeg muag khoom muaj ob hom. Active PFC muaj ntau yam zoo. Nws siv lub tshuab hluav taws xob hloov hluav taws xob kom lub zog hluav taws xob tuaj yeem ncav cuag 95% (txoj kev xav).
Tsis tas li ntawd, Active PFC tseem muaj peev xwm tshem tawm cov suab nrov thiab cov kab hluav taws xob sib dhos (tso cai rau koj ntsaws rau hauv ib qho chaw 110V rau 220V qhov hluav taws xob yam tsis tas yuav txhawj txog cov ntsuas). Txawm li cas los xij, vim yog cov qauv tsim ntawm Active PFC, cov khoom siv hluav taws xob siv cov thev naus laus zis no kim heev.
PFC fais fab mov; Active thiab Passive
Hauv2 tus pin fais fab qaum nrog VDE ntawv pov thawj;PFC cov khoom siv hluav taws xob yog siv los ua kom muaj zog ntxiv. Qee cov khoom siv hluav taws xob PFC tseem tso cai rau tus neeg siv siv lub hloov pauv uas txiav txim siab cov tswv yim tam sim no. Passive PFC: Qhov no yog ntau hom niaj hnub no. Tsis zoo li Active PFC, Passive PFC dlhos qhov tam sim no los ntawm cov lim capacitors thiab yog li ntawd nws lub peev xwm ua hauj lwm yuav raug hloov raws sij hawm.
Ntxiv mus, nws yuav cuam tshuam los ntawm lwm yam xws li kub, poob siab. Cov khoom siv hluav taws xob siv Passive PFC thev naus laus zis xav kom tus neeg siv kho qhov hluav taws xob nkag ntawm qhov hloov me me. Passive PFC qhov chaw pheej yig dua li Active PFC qhov chaw.
Kho lub lauj kaub hauv qab 2 tus pin fais fab qaum nrog VDE ntawv pov thawj
Qee cov khoom siv hluav taws xob zoo tuaj nrog cov potentiometers me me sab hauv los kho qhov voltages ntawm cov kab hluav taws xob. Qhov tseeb, yog tias koj cov kab hluav taws xob 12V poob qis dua 11.5V, nws yuav ua rau tsis ruaj khov rau tag nrho cov kab ke. Nco ntsoov tias tus qauv ATX tso cai rau qhov voltage ntawm ib kab kom hloov pauv.
Txawm li cas los xij, qhov no yog qhov ua tau zoo tshaj plaws thiab tsuas yog yuav tsum tau ua yog tias koj paub tias koj ua dab tsi. Qee cov khoom siv hluav taws xob tag nrho hloov cov potentiometers tawm rau cov neeg siv hloov pauv dawb, xws li Antec's True Control series.
Soft Power hom thiab 5V. Standby teeb liab
Soft Power yog txoj hauv kev uas lub khoos phis tawj 2 tus pin fais fab qaum qhib lossis kaw, tab sis tsis yog siv lub zog hloov pauv zoo li qub AT tus qauv, nws tau qhib thaum BMC hais kom 2 tus pin fais fab qaum.2 tus pin fais fab qaum nrog VDE ntawv pov thawjyog siv feem ntau hauv cov khoom siv xws li moos, xov tooj cua, thiab lub charger ntawm cov roj teeb.
Koj tuaj yeem tshawb xyuas qhov no yooj yim nrog lub peev xwm kaw lub Windows operating system lossis qhib lub computer los ntawm cov keyboard thiab nas. Txoj cai tseem ceeb rau BMC kom txib 2 tus pin fais fab qaum yog los ntawm cov teeb liab standby ntawm +5V Standby kab.
Cov kab hluav taws xob thiab nws hom
Cov kab hluav taws xob no muaj kev ywj pheej tag nrho los ntawm lwm cov khoom siv thiab yuav muaj teeb liab thaum twg koj ntsaws rau hauv lub hwj chim, qee qhov BMCs tshiab feem ntau muaj lub teeb liab los qhia +5 V Standby xwm txheej. Tsis tas li ntawd, muaj ob peb lwm yam kev pabcuam fais fab ntawm lub khoos phis tawj, suav nrog:
Inductive kab +3.3V (+3.3V Sense): Lub luag haujlwm tseem ceeb yog saib xyuas qhov voltage ntawm +3.3V kab los pub BMC. 2 tus pin fais fab qaum tuaj yeem kho qhov tam sim no kom raug.
Lub kiv cua ua haujlwm li cas nyob ntawm qhov voltage?
Thaum qhov hluav taws xob ntawm cov kab no poob qis dua 1 V, tus kiv cua yuav cia li tua. Thaum tus nqi siab tshaj 10.5 V mus txog, tus kiv cua yuav ua haujlwm ntawm lub peev xwm. Lub luag haujlwm tseem ceeb ntawm qhov kev tsim no yog tso cai rau lub kaw lus kaw kiv cua.
Ntxuam saib (Ntxuam saib): Qhov no yog ib tug khub rau tus kiv cua tswj feature; nws tso cai rau saib xyuas cov kiv cua kev sib hloov ceev hauv qhov system. Nws lub luag haujlwm tseem ceeb yog ceeb toom cov neeg siv thaum qee lub kiv cua txias ua haujlwm tsis zoo thiab tsis ua haujlwm.
Cov ntsiab lus tseem ceeb ntawm lub computer zoo 2 tus pin fais fab qaum
Kev ruaj ntseg ntawm cov zis hluav taws xob: Qhov hluav taws xob tsis sib txawv los ntawm ntau dua -5 txog +5% ntawm qhov ntsuas hluav taws xob (qhia rau ntawm 2 tus pin fais fab qaum) thaum lub hauv paus ua haujlwm rau nws lub peev xwm tsim.
Cov zis voltage yog tiaj tus, tsis muaj kev cuam tshuam.
Kev ua haujlwm siab, ncav cuag ntau dua 80% (Tshaj tawm / tawm tswv yim txog> 80%)
2 tus pin fais fab qaum nrog VDE ntawv pov thawjTsis txhob siv cov khoom sib nqus, hluav taws xob, cuam tshuam rau lwm qhov chaw nyob ib puag ncig nws thiab yuav tsum tiv thaiv cov hlau nplaum, hluav taws xob, cuam tshuam los ntawm lwm yam khoom nyob ib puag ncig nws.
Thaum lub sijhawm ua haujlwm, 2 tus pin fais fab qaum ua kom muaj cua sov me ntsis, thiab lub suab nrov me me.
Cov xov hlau tso tawm muaj ntau haiv neeg, nrog ntau tus qauv pins, zoo zoo qhwv thiab tiv thaiv kev cuam tshuam.
Ua kom ruaj khov ua haujlwm nrog lub peev xwm tsim rau lub sijhawm ua haujlwm ntev.
Nco tseg: Ib yam uas koj yuav tsum nco ntsoov yog tias cov khoom siv hluav taws xob txheem yuav tsum muaj cov ntawv pov thawj zoo, nrog rau cov kev txwv xws li lub zog muaj peev xwm, qhov hluav taws xob, thiab lwm yam.
Yuav ua li cas yuav txoj cai 2 tus pin fais fab qaum nrog lub peev xwm ntawm kev suav?
Yog lawm, nyob rau hauv tsab xov xwm dhau los, kuv tau qhia kuv qhov kev paub ntawm kev suav lub computer siv zog. Yog tias koj tsis tau nyeem nws, thov tshuaj xyuas cov lus qhia no: Ntxiv mus, koj yuav pom cov lus qhia rau kev suav lub zog siv ntawm lub khoos phis tawj desktop (PC).
Yog koj xaiv; ib qho 2 tus pin fais fab qaum uas tsis mus txog qhov cim; nws yuav cuam tshuam rau koj qhov system ua haujlwm. Nws yog thawj zaug yuav tsum muaj 2 tus pin fais fab qaum, uas ua haujlwm zoo tshaj rau koj. Koj yuav tsum coj qhov no mus rau hauv tus account thiab ua rau cov2-pin fais fab qaum nrog VDE ntawv pov thawj. Nws yuav muab rau koj xav tau specifications.
Epilogue
Okay, uas yog cov ncauj lus kom ntxaws thiab meej, puas yog? Cov no yog cov kev paub uas kuv pom zoo heev thiab muaj txiaj ntsig zoo uas koj yuav tsum paub txog cov khoom siv hluav taws xob hauv computer. Yuav kom paub meej ntxiv, nws yuav siv sij hawm ntev dua, tab sis peb tsuas yog xav paub cov ntsiab lus saum toj no thiab nws zoo heev
