Dab tsi yog adjustable tswj fais fab mov
Cias muab tso, qhov tso zis voltage yog adjustable, thiab tom qab raug kho rau tus nqi tso zis, cov zis yog ruaj khov thaum lub zog input thiab voltage fluctuations tsis loj heev.
Feem ntau, muaj ntau hom khoom siv hluav taws xob kho tau uas tuaj yeem hloov AC rau DC, thiab kev faib tawm ntawm DC rau DC kuj txawv raws li ntau hom. Tam sim no, cov zis hluav taws xob ntawm ntau cov khoom siv hluav taws xob hloov pauv kuj tseem tuaj yeem kho tau, tab sis qhov hloov kho tau tsis loj, thiab muaj ntau yam tshwj xeeb tsim cov khoom siv hluav taws xob hauv khw, thiab ntau yam DC-DC adjustable regulated fais fab mov modules hloov tau yooj yim, thiab adjustable ntau yam yog dav. Muaj ntau 1.25-30v. Raws li kev sib raug zoo ntawm cov input voltage thiab cov zis voltage, nws muaj peev xwm muab faib ua step-down, step-up, step-up thiab step-down adjustable regulated fais fab mov. Tsuas yog lub pob-boost adjustable fais fab mov, qhov tso zis voltage tuaj yeem hloov kho arbitrarily nyob rau hauv qhov tso zis ntau yam, thiab tsis muaj qhov sib txawv ntawm qhov sib txawv nrog cov input voltage, thiab lwm tus xav tau qee qhov voltage sib txawv los ua haujlwm ruaj khov rau lub sijhawm ntev. vam tias qhov no yuav pab tau!
Yuav ua li cas kho lub 30v5a adjustable DC tswj fais fab mov
Thawj kauj ruam yog kom disassemble nws kom pom tias AC voltage tso zis yog qhov qub lossis tsis txiav txim siab ib nrab ntawm qhov txhaum nyob rau hauv pem hauv ntej thiab nram qab, thiab tom qab ntawd ua tib zoo tshawb nrhiav ib nrab ntawm qhov txhaum kom txo qis qhov ntsuas, thiab thaum kawg txiav txim siab seb puas yog. cov khoom puas lawm.
Dab tsi yog lub hauv paus ntsiab lus ntawm kev hloov kho DC tswj fais fab mov
Tom qab qhov hloov pauv tam sim no raug kho thiab lim los ntawm diodes, nws dhau los ntawm lub zog loj thiab nruab nrab triodes, thiab lub zog siab thiab nruab nrab triodes coj thiab tso tawm hluav taws xob los ntawm kev ua haujlwm. Qee cov qauv tsim txuas cov resistor nyob rau hauv series kom lub zog Zener diode ua ntej voltage stabilization, kom muaj qhov ruaj khov voltage sib txawv ntawm ob tug ncej ntawm lub diode, thiab qee qhov qauv tsim yog tom qab cov zis triode. Qhov hluav taws xob ruaj khov no hu ua qhov siv hluav taws xob.
Tom qab ntawd siv lub triode los yog kev sib xyaw ua ke ua ib qho kev sib piv, (ntxiv rau cov zis) ib kawg yog txuas nrog rau qhov siv hluav taws xob, thiab lwm qhov kawg (b) txuas nrog nruab nrab ntawm qhov hloov kho ntawm qhov hloov kho tau nrog qhov tam sim no limiting resistor hauv series, thiab lwm ob txhais ceg ntawm adjustable resistor yog txuas nrog ob tug ncej ntawm cov zis voltage . Kuj tseem muaj ib tug ncej txuas nrog b ncej ntawm lub loj thiab nruab nrab lub zog triode, uas tswj thiab kho cov conduction ntawm triode. Qhov hluav taws xob tuaj yeem hloov kho los ntawm kev hloov kho qhov hloov kho resistor.
Yooj yim muab tso, lub hauv paus ntsiab lus yog tias qhov tso zis hluav taws xob tau muab piv nrog qhov siv hluav taws xob los ntawm kev sib piv cov raj (kev thaiv kev sib txuas) los tswj cov kev hloov pauv tam sim no thiab qhov hluav taws xob ntawm qhov loj thiab nruab nrab fais fab transistors kom ua tiav lub hom phiaj ntawm voltage stabilization. Cov zis hluav taws xob tuaj yeem hloov kho los ntawm kev kho qhov sib piv voltage ntawm lub raj sib piv (manifold).
