Mmene angagwiritsire ntchito voteji yang'anira 12 volts

Mphamvu kumatanthauza madera gwero kuti amplifiers ntchito magwero mphamvu otsika zambiri ntchito volts angapo (12-15). Pakali pano, lofalitsidwa koposa kufalitsa Volt voteji yang'anira 12 kukhazikitsidwa ntchito atatu osachiritsika mayunitsi Integrated. cholinga chawo kupeza chosiyana linanena bungwe voteji ndi ukulu wa mphamvu ya magetsi. Main zigawo zikuluzikulu - Integrated madera ndi KR142EN8B zoweta kupanga ndi kunja analogues mndandanda MS78hh ndi MS79hh kapena 78hh chabe ndi 79hh.

Mitundu zoweta ndi achilendo wa stabilizers

Russian KR142EN8B yofunika Unit (chidule dzina KREN8B) imapereka zachilendo linanena bungwe voteji wa volts khumi.

Kunja stabilizers zatchulidwazi mndandanda ndi mayina otsatirawa: koyamba chiwerengero (78) chimasonyeza cholinga - zabwino linanena bungwe panopa, wosamvetseka chiwerengero (79) - oipa linanena bungwe voteji. The manambala awiri otsiriza (12 kapena 05) zimasonyeza mphamvu linanena bungwe la magetsi. Mwachitsanzo: 7912 - IC - 12V voteji yang'anira ndi zoipa polarity, 7805 - Chip - unit chomwecho, volts 5 okha ndi polarity positive.

Atatu osachiritsika yang'anira kuti dzina limeneli m'Chingelezi, ali zotuluka atatu kuti kupereka mogwirizana ndi dera kunja magetsi: athandizira, linanena bungwe ndi akukhudzidwira. Kulumikiza ndi mphamvu zoyendetsera nyumba ( "dziko") akugwiritsa ntchito linanena bungwe wamba. Athandizira ndi malo ofanana ntchito kupereka athandizira voteji ndi linanena bungwe ife titi ntchito pa mfundo ya "kuchoka" ndi "wamba".

The voteji yang'anira 12 volts ntchito zambiri mu mulanduwo, ngati athandizira panopa pamene pazipita chovomerezeka katundu linanena bungwe kuposa osachepera 2.5 volts. Mtengo wa pazipita mphamvu athandizira sayenera upambana volts makumi atatu. Komanso, dziwani kuti kuchuluka athandizira voteji amapereka mphamvu phindu, 12b stabilizer akuyamba usavutike. Choncho, m'pofunika kuteteza ntchito koziziritsira.

Standard mphamvu okwanira ndi anasonkhana ku electrolytic capacitor kuti microfarads 10,000 zonse yoweyula mlatho rectifier wa diodes ndi voteji n'zosiyana 50 volts mwachindunji panopa ndi 3a, ndi lama fuyusi (0.5 A). voteji yang'anira yekha 12 volts - 7912 kapena 7812 (KREN8B).

Pogwiritsa ntchito zida anasonkhana makina amenewa amafuna kuika zigawo zikuluzikulu zamakono mu njira yakuti kutalika pakati ogwiritsa mankhwala anali otsika, ndi kuchotsedwa kwa rediyeta wa - waukulu. Pakuti kuzirala, ndi bwino kutenga muyezo ribbed radiators a m'dera chokwanira padziko, kapena mbale zitsulo.

Magwero kutsatira yophatikiza voteji yang'anira 12 volts, zimathandiza ntchito zawo kwa magetsi a mitundu yosiyanasiyana ya zipangizo ndi midadada anaphedwa ndi ntchito TTL Integrated madera mfundo, kuphatikizapo zipangizo galimoto magalimoto.
