Main Function
Lub luag haujlwm tseem ceeb ntawm qhov ntsuas hluav taws xob.
1. Voltage stabilization.
Thaum daim phiaj hluav taws xob hloov pauv sai sai, tus tswj hluav taws xob yuav them rau qhov voltage amplitude nrog cov lus teb ceev ntawm 10-30ms, ua rau nws ruaj khov hauv ± 2%.
2. multi-functional integrated kev tiv thaiv.
Lub voltage regulator ntxiv rau qhov yooj yim tshaj plaws stabilization ntawm lub zog muaj nuj nqi yuav tsum muaj kev tiv thaiv overvoltage (ntau tshaj +10% ntawm cov zis voltage), under-voltage tiv thaiv (tsawg dua -10% ntawm cov zis voltage), theem tsis ua hauj lwm tiv thaiv. , luv Circuit Court overload tiv thaiv qhov yooj yim tshaj plaws tiv thaiv kev ua haujlwm.
3. Spike pulse suppression (yeem).
Daim phiaj hluav taws xob qee zaum muaj qhov siab heev, qhov dav pulse yog qhov nqaim heev, thiab nws yuav tawg los ntawm cov hluav taws xob qis tiv thaiv hluav taws xob.Cov khoom tiv thaiv hluav taws xob ntawm cov khoom siv hluav taws xob tswj tau tuaj yeem ua lub luag haujlwm zoo heev hauv kev tawm tsam xws li cov pulses ntse.
4. Kev rho tawm ntawm cov hluav taws xob EMI electromagnetic cuam tshuam (yeem).
Cov khoom siv CNC ntau AC / DC rectifier + PFC high-frequency fais fab xwm txheej kho, nws tus kheej muaj qee qhov cuam tshuam tib lub sijhawm ntawm qhov cuam tshuam kuj muaj cov cai nruj.Cov khoom siv hluav taws xob tswj tau zoo tuaj yeem cais cov kab sib chaws cuam tshuam rau cov cuab yeej siv tib lub sijhawm kuj tseem tuaj yeem cais cov cuab yeej cuam tshuam rau daim phiaj.
5. Kev tiv thaiv xob laim (yeem).
Yuav tsum muaj lub peev xwm los tiv thaiv xob laim.
Pawg
DC voltage regulator yuav muab faib ua ob pawg.
1, hloov hom
Ib hom sib txawv ntawm cov khoom siv hluav taws xob ruaj khov los ntawm cov kab hluav taws xob tswj hluav taws xob yog qhov hloov pauv hom DC tswj fais fab mov, uas muaj ib hom hluav taws xob ntawm ib leeg-kawg flyback, ib leeg-kawg rau pem hauv ntej, ib nrab-bridge, thawb-rub thiab tag nrho-bridge.Qhov sib txawv ntawm qhov no thiab cov khoom siv hluav taws xob tawm yog qhov hloov pauv tsis ua haujlwm ntawm kev ua haujlwm zaus tab sis kaum ntawm kilohertz mus rau ob peb megahertz.Tube muaj nuj nqi tsis ua hauj lwm nyob rau hauv lub saturation thiab txiav-off cheeb tsam uas yog lub xeev switching;switching power supply li npe.
2, Linear
Lub linear voltage regulator muaj ib tug zoo feature nyob rau hauv hais tias nws lub hwj chim ntaus ntawv regulator raj ua hauj lwm nyob rau hauv lub linear cheeb tsam, cia siab rau lub voltage poob ntawm lub regulator raj kom stabilize cov zis.Vim qhov loj zoo li qub poob ntawm lub regulator raj, ib tug loj kub dab dej yuav tsum tau muab ntsia rau dissipate cua sov rau nws.Lub transformer kuj hnyav dua vim nws ua haujlwm ntawm 50Hz.
Qhov zoo ntawm cov khoom siv fais fab no yog qhov ruaj khov, me me ripple, kev ntseeg siab, yooj yim rau ntau yam, tsis tu ncua adjustable tso zis ntawm cov khoom tiav.Qhov tsis zoo yog tias lawv loj, loj, thiab tsis muaj zog.Hom khoom siv hluav taws xob ruaj khov no thiab muaj ntau yam, los ntawm qhov xwm txheej ntawm cov zis tuaj yeem muab faib ua qhov voltage stabilized fais fab mov thiab tam sim no stabilized fais fab mov thiab teeb voltage stabilization, tam sim no stabilization nyob rau hauv ib tug ruaj khov voltage, thiab tam sim no (dual-stable. ) lub zog.Tus nqi tso zis tuaj yeem muab faib ua cov khoom siv hluav taws xob ruaj khov, hloov pauv-kho, thiab potentiometer tsis tu ncua kho ntau yam.Los ntawm cov zis, qhov qhia tau muab faib ua pointer indication type thiab digital display type, thiab lwm yam.
Qhia
DC hloov hluav taws xob khoom siv.
Qhov zoo ntawm kev hloov cov khoom siv hluav taws xob yog lawv qhov me me, lub teeb yuag, ruaj khov, thiab kev ntseeg tau.Lawv muaj nyob rau hauv lub zog ntawm ob peb watts mus rau ob peb kilowatts.Nov yog ob peb yam khoom siv hluav taws xob hloov
1. Cov khoom siv hluav taws xob sib txuas lus
Kev sib txuas lus fais fab mov yog qhov tseem ceeb ntawm DC / DC converter hom fais fab mov, tab sis nws feem ntau yog DC-48V lossis -24V fais fab mov, thiab cov roj teeb thaub qab rau DC fais fab mov, DC muab hluav taws xob rau hauv qhov hluav taws xob ua haujlwm, feem ntau yog muab faib rau hauv nruab nrab fais fab mov, txheej fais fab mov, thiab ib lub rooj fais fab mov peb, qhov tom kawg yog qhov kev ntseeg siab tshaj plaws.
2. AC/DC
Hom kev siv fais fab no, tseem hu ua thawj lub zog hluav taws xob, tau txais lub zog los ntawm daim phiaj hluav taws xob thiab tau txais DC high voltage los ntawm high voltage rectification thiab lim rau DC / DC converter kom tau txais ib lossis ntau qhov ruaj khov DC voltages ntawm cov zis, nrog hwj chim xws li los ntawm ob peb watts mus rau ob peb kilowatts.Muaj ntau yam kev qhia tshwj xeeb rau cov khoom zoo li no, thiab cov khoom siv hluav taws xob tseem ceeb (AC220 tawm tswv yim, DC48V, lossis 24V tso zis) hauv kev sib txuas lus fais fab mov kuj yog hom no, nyob ntawm qhov xav tau ntawm tus neeg siv.
3. Modular fais fab mov
Nrog rau txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, kev ntseeg siab ntawm lub zog hluav taws xob, thiab lub peev xwm / ntim qhov sib piv yog nce siab, lub module fais fab mov yog nce qhia nws superiority, nws ua hauj lwm nyob rau hauv ib tug high zaus, me me, muaj kev ntseeg siab, yooj yim installation. thiab kev sib xyaw ua ke ntawm kev nthuav dav, yog li ntau thiab ntau siv dav.Txawm hais tias muaj kev sib raug zoo hauv tsev module ntau lawm, vim tias cov txheej txheem ntau lawm tsis tau ntes nrog cov qib thoob ntiaj teb, qhov ua tsis tiav yog siab.
4. Xov tooj cua fais fab mov
Xov tooj cua fais fab mov input AC220V / 110V, tso zis DC13.8V, lub zog los ntawm lub hwj chim ntawm lub xov tooj cua chaw nres tsheb, ob peb amps, thiab ntau pua amps muaj.Txhawm rau tiv thaiv AC daim phiaj hluav taws xob tsis ua haujlwm los cuam tshuam rau lub xov tooj cua ua haujlwm, thiab yuav tsum muaj lub roj teeb pob ua cov thaub qab, yog li cov khoom siv hluav taws xob zoo li no ntxiv rau cov zis ntawm 13.8V DC voltage kuj muaj lub roj teeb them tsis siv neeg hloov pauv.
5. DC / DC
Hauv kev sib txuas lus, tseem hu ua cov khoom siv hluav taws xob thib ob, nws yog thawj lub zog hluav taws xob lossis DC roj teeb pob los muab DC input voltage, tom qab DC / DC hloov dua siab tshiab ntawm sab tso zis kom tau txais DC voltage lossis ob peb DC voltages.
Txawm hais tias DC / DC module fais fab mov yog kim dua, los ntawm qhov pom ntawm tag nrho cov nqi ntawm cov khoom siv lub voj voog ntev, tshwj xeeb tshaj yog vim qhov system tsis ua haujlwm thiab tus nqi siab ntawm kev saib xyuas thiab kev poob siab, kev xaiv ntawm lub zog module. tseem yog tus nqi zoo, nws tseem tsim nyog hais txog ntawm no yog Roche converter circuit, nws qhov zoo tshaj plaws yog cov qauv yooj yim ntawm lub voj voog, kev ua haujlwm siab thiab cov zis voltage thiab tam sim no ripple tus nqi zero.
6. Cov khoom siv hluav taws xob tshwj xeeb
Cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob tam sim no, cov khoom siv hluav taws xob siab tam sim no, 400Hz input AC / DC cov khoom siv hluav taws xob, thiab lwm yam tuaj yeem raug cais raws li qhov xav tau tshwj xeeb.
Hais txog cov khoom
LM5010 step-down switching regulator nta tag nrho cov haujlwm uas xav tau los siv tus nqi qis, ua haujlwm tau zoo, buck bias regulator muaj peev xwm muab ntau tshaj 1-A load tam sim no.Lub tshuab hluav taws xob siab no muaj N-Channel Buck Hloov, thiab muaj nyob rau hauv cov khoom siv thermally txhim kho 10-pin WSON thiab 14-pin HTSSOP pob.Cov txheej txheem kev cai hysteretic yuav tsum tsis muaj qhov nyiaj them rov qab, ua rau cov lus teb nrawm nrawm, thiab ua kom yooj yim rau kev siv hluav taws xob.Kev khiav hauj lwm zaus tseem nyob tas li nrog cov kab thiab kev thauj khoom sib txawv vim qhov kev sib cuam tshuam ntawm cov input voltage thiab ON-time.Qhov ntsuas qhov ntsuas tam sim no yog teem rau ntawm 1.25 A. Cov yam ntxwv ntxiv muaj xws li: VCC undervoltage lockout, thermal shutdown, lub rooj vag tsav undervoltage lockout, thiab lub luag haujlwm siab tshaj plaws lub voj voog limiter.
