How kushandisa voltage regulator 12 volts

Sokurondedzera matunhu kunobva simba operative amplifiers yakaderera zvinyorwa simba kakawanda zvinoshandiswa dzakawanda volts (12-15). Pari, inonyanya kuparadzira volt voltage regulator 12 configured kushandisa-chinouraya matatu Integrated dzakabatana. chinangwa kwavo kuwana yakasiyana goho voltage uye kwakakura remagetsi. Main zvinoriumba - revatema nematunhu ari KR142EN8B mumhuri kugadzirwa uye kupinza analogues dzakatevedzana MS78hh uye MS79hh kana chete 78hh uye 79hh.

Domestic uye vatorwa marudzi stabilizers

Russian KR142EN8B chinokosha chikwata (rakapfupikiswa zita KREN8B) inopa zvinoitika goho voltage gumi volts.

Kupinza stabilizers rataurwa dzakatevedzana dzine zvinotevera mazita: kutanga kunyange nhamba (78) inoratidza chinangwa - zvakanaka goho ano, imwe vasinganzwisisike nhamba (79) - akaipa goho voltage. Okupedzisira digits maviri (12 kana 05) anoratidza kuti goho simba remagetsi. Somuenzaniso: 7912 - IC - 12V voltage regulator nezvisingafadzi polarity, 7805 - Chip - zvakafanana Unit, 5 chete volts uye uine polarity.

Three-chinouraya regulator sezvo zita rayo rinoratidza, ane outputs zvitatu zvinopa kubatana kuti zvemagetsi remudunhu zvokunze: chiyamuro, goho uye kwose. Kubatanidza kuti simba rine pekugara ( "nyika") anoshandisa zvakafanana goho. The chiyamuro uye zvakajairika zviteshi zvinoshandiswa kupa mazano voltage uye goho tinowana kushanda ndezvipi zviri "buda" uye "zvakafanana".

The voltage regulator 12 volts zvinoshanda anowanzoita panyaya, kana mazano pari apo vaifanira bvumidzwa mutoro goho kwazvo zvinenge 2.5 volts. The kukosha kunonyanyisa simba chiyamuro haafaniri kupfuudza matatu volts. Uyewo, cherechedza kuti chichiwedzera chiyamuro voltage kunopa simba dzokusatendeseka, 12b stabilizer hunotanga neshungu. Saka, zvinokosha kuti kudzivirira kukuvara kushandisa kupisa singi.

Standard simba zvitengeswa riri vakaungana kubva electrolytic capacitor kusvika 10,000 microfarads, wenguva-wave bhiriji rectifier pamusoro diodes ane neizvi voltage 50 volts yakananga kuitika uye 3A, kuti fiyuzi (0.5 A). voltage regulator pachake 12 volts - 7912 kana 7812 (KREN8B).

Kushandisa vakaungana midziyo kuti muchina kudaro zvinoda Positioning yemagetsi zvinoriumba nenzira yakadaro kuti kureba pakati vanomhanyisa yeimwe aiva kugomba ravakafa, uye kubviswa redhiyeta - pakukura. Nokuti kutonhora, zvakanakisisa kutora mureza ribbed radiators ose yakakwana pamusoro nzvimbo, kana simbi ndiro.

Sources kushandisa chinayo voltage regulator 12 volts, anobvumira kushandiswa kwavo simba nerubatsiro marudzi mano namatombo vakaurayiwa pamwe nokushandiswa TTL revatema pfungwa nematunhu, kusanganisira mano kuti Automotive motokari.
