Transformer ya 12V nthawi zambiri imakhala chipangizo cha AC. Mwamphamvu yamagetsi, thiransifoma imagwira ntchito ndi ma alternating current ndikusintha voteji ya AC kuchokera pamlingo wina kupita pa wina. Mwachitsanzo, thiransifoma yachikhalidwe ya 12V imatha kupondaponda 120V AC, 230V AC, kapena kuyika kwina kwa AC mpaka 12V AC.
Komabe, anthu ambiri amagwiritsa ntchito mawu oti "transformer" mwachisawawa pofotokoza chipangizo chilichonse chomwe chimatembenuza mphamvu ya mains kukhala 12V. Izi zitha kuyambitsa chisokonezo. Ngati zotsatira zake ndi 12V DC, chipangizocho sichimangosintha. Nthawi zambiri imakhala magetsi, adapter, driver, kapena converter yomwe imaphatikizapo kukonzanso ndi kuwongolera. Ichi ndichifukwa chake chinthu chofotokozedwa ngati a 12v dc thiransifoma ziyenera kufufuzidwa mosamala kuti zitsimikizire ngati zimatulutsa AC kapena DC.
Kodi Transformer Imachita Chiyani Kwenikweni?
Transformer imasamutsa mphamvu zamagetsi pakati pa ma windings awiri kudzera mu electromagnetic induction. Imatha kutsitsa ma voltage, kukweza ma voltage, kapena kupereka kudzipatula pakati pa mabwalo.
Transformer yoyambira ili ndi:
- Kusamba koyambirira
- Mphepo yachiwiri
- Maginito pachimake
- Insulation system
- Ma terminal kapena otsogolera
- Enclosure kapena mounting structure
Transformer imafuna kulowetsa kwa AC chifukwa kusintha kwa maginito kumafunika kuti pakhale magetsi pamapiritsi achiwiri. DC Yoyera sipanga maginito omwe amasintha mosalekeza mu thiransifoma yokhazikika.
Kodi 12V Output AC kapena DC?
Yankho limadalira mankhwala.
12VAC thiransifoma imatulutsa zosintha zapano. Izi ndizofala m'malo ounikira, mabelu a pakhomo, magetsi a m'madzi, makina owongolera, ndi makina akale amagetsi otsika.
Mphamvu yamagetsi ya 12VDC imatulutsa molunjika. Izi ndizofala m'mizere ya LED, makamera a CCTV, ma router, ma board owongolera, masensa, ma mota, ndi zamagetsi.
Ngati chizindikiro chikuti "Output: 12V AC," ndi thiransifoma ya AC. Ngati imati "Kutulutsa: 12V DC," ndi magetsi a DC kapena adapter, ngakhale ogulitsa ena amatcha thiransifoma.
Kodi 12 V DC Transformer ndi chiyani?
Mawu akuti 12v dc thiransifoma amagwiritsidwa ntchito kwambiri pakufufuza kwazinthu zatsiku ndi tsiku, koma mwaukadaulo nthawi zambiri amatanthauza magetsi a 12V DC. Mkati mwa chipangizocho, pakhoza kukhala chosinthira kapena chosinthira pafupipafupi, kuphatikiza zigawo zomwe zimasinthira AC kukhala DC.
Mphamvu yamagetsi ya 12V DC ingaphatikizepo:
- Chitetezo cholowa
- Transformer kapena kusintha dera
- Wokonzanso
- Sefa capacitor
- Voltage regulation circuit
- Chitetezo chotuluka
- Enclosure ndi ma terminals
Wokonzanso amasintha AC kukhala DC, pomwe chowongolera chimathandizira kuti magetsi azikhala okhazikika.
Momwe Mungawerengere Chizindikiro
Njira yachangu kwambiri yodziwira kutulutsa kwa AC kapena DC ndikuwunika zomwe zili patsamba.
Yang'anani:
- Mphamvu yamagetsi
- Chizindikiro cha AC kapena DC
- Mavoti apano
- Wattage
- Mphamvu yamagetsi
- Chizindikiro cha polarity
- pafupipafupi
- Satifiketi yachitetezo
- M'nyumba kapena kunja
Chizindikiro cha AC chikhoza kuwoneka ngati mzere wavy. Chizindikiro cha DC chikhoza kuwoneka ngati mzere wowongoka wokhala ndi mzere wodutsa pansi pake. Magetsi a DC nthawi zambiri amawonetsa polarity, monga pakati-zabwino kapena pakati-negative, zolumikizira migolo.
Chifukwa chiyani AC vs. DC Ikufunika
Kugwiritsa ntchito mtundu wolakwika kumatha kuwononga zida kapena kuzilepheretsa kugwira ntchito.
Mwachitsanzo, kuwala kwa 12V AC kungagwire ntchito ndi 12VAC thiransifoma, koma 12V DC Mzere wa LED nthawi zambiri umafunika magetsi a 12VDC. Kamera ya 12V DC yolumikizidwa ndi 12V AC ikhoza kulephera. Chipangizo cha 12V AC cholumikizidwa ndi DC mwina sichingagwire bwino ntchito.
Musanalumikize chipangizo chilichonse, tsimikizirani:
- Mphamvu yamagetsi yofunika
- Zofunikira za AC kapena DC
- Zojambula zamakono
- Mtundu wa cholumikizira
- Polarity kwa DC
- Kugwiritsa ntchito m'nyumba kapena kunja
- Mtundu wa katundu
- Kuyika chilengedwe
Kugwiritsa Ntchito Wamba kwa 12VAC Transformers
Zosintha za 12VAC nthawi zambiri zimagwiritsidwa ntchito pamakina otsika kwambiri omwe safuna mwachindunji.
Ntchito zodziwika bwino ndi izi:
- Kuwala kwa malo
- Kachitidwe ka mabelu a pakhomo
- Ena owongolera ulimi wothirira
- Pool ndi spa kuyatsa
- Low-voltage halogen nyali
- Makina ena owongolera a HVAC
- Zozungulira ma alarm
- Magawo owongolera mafakitale
Makinawa amatha kupangidwira kuti azigwira ntchito ndi AC.
Kugwiritsa Ntchito Wamba kwa 12VDC Power Supplies
Mphamvu zamagetsi za 12VDC ndizofala pamagetsi ndi zida zamakono zotsika kwambiri.
Zomwe zimagwiritsidwa ntchito ndizo:
- Zowunikira za LED
- Makamera achitetezo
- Njira zowongolera zofikira
- Ma routers ndi modem
- Zomverera
- Ma motors ang'onoang'ono a DC
- Makina owongolera
- Zida zomvera
- Mabwalo othandizira kuyitanitsa mabatire
- Zowonetsera zamagetsi
Kwa mapulogalamu awa, a 12v dc thiransifoma iyenera kupereka zotulutsa zokhazikika za DC zokhala ndi mphamvu zokwanira pakalipano pa katundu wolumikizidwa.
Linear vs. Kusintha kwa 12V Power Devices
Zida zamagetsi zotsika mphamvu zimatha kugwiritsa ntchito mizere yozungulira kapena yosinthira.
Ma Linear Transformers
Liniya transformer nthawi zambiri imakhala yolemera chifukwa imagwiritsa ntchito chitsulo pakati pa mains frequency. Itha kutulutsa AC mwachindunji, kapena ikhoza kukhala gawo lamagetsi amagetsi a DC omwe amawongolera komanso kusefa.
Kusintha Magetsi
Mphamvu yosinthira nthawi zambiri imakhala yaying'ono komanso yopepuka. Imatembenuza magetsi pafupipafupi ndipo imatha kupereka zotulutsa zoyendetsedwa bwino za DC. Ma adapter amakono a 12VDC amagwiritsa ntchito ukadaulo wosinthira.
Mitundu yonse iwiriyi imatha kukhala yothandiza, koma kusankha koyenera kumatengera kachulukidwe, kukhudzika kwa phokoso, kufunikira kwachangu, komanso momwe mungayikitsire.
Momwe Mungasankhire Chipangizo Choyenera cha 12V
Posankha chosinthira cha 12V kapena magetsi, lingalirani:
- Kodi zida zimafunikira AC kapena DC?
- Ndi kulekerera kwamagetsi kotani komwe kumaloledwa?
- Ndi ma amps angati omwe amafunikira?
- Ndi madzi otani omwe amafunikira?
- Kodi katunduyo ndi wopitilira kapena wapakatikati?
- Kodi chipangizochi ndi chamkati kapena chakunja?
- Kodi imafunika chitetezo chopanda madzi?
- Kodi polarity ya DC ilibe kanthu?
- Kodi chitetezo cha overcurrent chikufunika?
- Kodi kukhazikitsa kumafunika kudzipatula?
- Kodi malamulo amagetsi am'deralo akugwira ntchito?
Kwa kuyatsa kwa LED ndi zamagetsi, sankhani magetsi a 12VDC oyendetsedwa. Pazowunikira za AC kapena makina owongolera, sankhani chosinthira 12VAC chovotera bwino.
Kukula kwa 12V Transformer kapena Power Supply
Mphamvu yamagetsi nthawi zambiri imawerengedwa ndi ma watts kapena ma volt-amps.
Kwa katundu wa DC:
Watts = volts x amps
Mwachitsanzo, chipangizo cha 12V DC chojambula 5 amps chimafunika pafupifupi ma watts 60. Nthawi zambiri zimakhala zanzeru kusankha magetsi okhala ndi mphamvu zowonjezera m'malo mongoyendetsa mosalekeza pamlingo wake waukulu.
Kwa katundu wa AC transformer, VA mlingo amagwiritsidwa ntchito nthawi zambiri. Transformer ya 12VAC yovoteledwa pa 100VA imatha kupereka pafupifupi 8.3 amps pa 12V pansi pamikhalidwe yovotera.
Zolinga Zachitetezo
Low voteji sizikutanthauza kuti palibe chiopsezo. Dongosolo la 12V limathabe kutenthetsa mawaya, kuwononga zida, kuyambitsa moto, kapena kuyambitsa zoopsa zamoto ngati zitalemedwa kapena kulumikizidwa molakwika. Mbali yoyamba ya thiransifoma kapena magetsi amathanso kulumikizidwa kumagetsi owopsa a mains.
Kuyika kuyenera kutsatira malangizo azinthu ndi zofunikira zamagetsi. Njira zakunja ziyenera kugwiritsa ntchito mipanda yoyenera yolimbana ndi nyengo komanso njira zolumikizira waya.
Mapeto
Transformer yeniyeni ya 12V nthawi zambiri imatulutsa 12V AC. Ngati chipangizo chimatulutsa 12V DC, nthawi zambiri chimakhala magetsi, adapter, dalaivala, kapena chosinthira, ngakhale chimatchedwa thiransifoma.
Chinsinsi ndicho kuyang'ana chizindikirocho ndikufananitsa zomwe zimachokera ku zipangizo. A 12v dc thiransifoma kusaka nthawi zambiri kumaloza kumagetsi a 12V DC, pomwe thiransifoma ya 12VAC imagwiritsidwa ntchito pamakina otsika a AC. Kusankha zotulutsa zolondola za AC kapena DC kumathandizira kuteteza zida, kukonza zodalirika, ndikuthandizira kukhazikitsa kotetezeka.
Kuti mudziwe zambiri zamagetsi amagetsi otsika komanso otsika, pitani JS Ndinyi.
