Kamoo u ka sebelisang ka gagamalo regulator 12 volts

Ka matla a ho hlalositswe lipotoloho mohloding ho amplifiers tshebetso ya mehloli matla tlaase hangata e sebelisoa ka volts 'maloa (12-15). Ho fihlela joale, ka ho fetisisa ho pharaletseng jala volt gagamalo regulator 12 di kentswe sebedisa tse tharo-seemelong diyuniti lotaganngwa. morero oa tsona ke ho fumana mokgwa o fapaneng khumo gagamalo le boholo ba jwale motlakase. Main dikarolo - kopantswe lipotoloho e KR142EN8B malapeng tlhahiso le imported analogues letoto la lihlooho tse MS78hh le MS79hh kapa 78hh feela le 79hh.

Mefuta e ruuoang le tsoang linaheng tse ling ba stabilizers

Russia KR142EN8B bohlokoa unit trust (khutsufalitsoe lebitso KREN8B) e fana ka le tloaelehileng khumo gagamalo tsa volts leshome le metso.

Imported stabilizers boletsoeng ka holimo letoto la lihlooho tse nang le litlotla tse latelang: ea pele esita le palo (78) bontša morero - positive, khumo jwale, e makatsa palo (79) - e mpe khumo gagamalo. The dinokong ho qetela tse peli (12 kapa 05) bontsha gore go ya matla khumo ea morao-rao ea motlakase. Mohlala: 7912 - edy - 12V gagamalo regulator le mpe polarity, 7805 - ladica i - yuniti e tšoanang, volts 5 feela le nang le polarity khothatsang.

Tse tharo-seemelong regulator ka lebitso la eona le bontša, e na le outputs tse tharo tse fanang ka mabapi ho e mong oa potoloho Link motlakase: input, khumo le ka kakaretso. Ho hokahanya ho matla a tsoang mohloling matlo ( "naha") o sebelisa khumo tloaelehileng. The input le boemelong ba tloaelehile hore batho ba li sebelisetsoa ho fana ka input gagamalo le khumo re fumana ho sebetsa ka liqeto tsa "tsoa" le "tloaelehileng".

The gagamalo regulator 12 volts tla sebetsa ka tsela e tloaelehileng ka ho le joalo, haeba input jwale ha palo e kahodimodimo lumeletsoe mojaro khumo feta bonyane 2,5 volts. Bohlokoa ba palo e kahodimodimo matla input lokela sa feteng volts mashome a mararo. Hape, ela hloko hore ho eketsehileng input gagamalo fana matla leruo la, 12b stabilizer qala ho halefile. Ka lebaka leo, ho ke ke ho hlokahala hore ho thibela tshenyo tšebeliso ea mocheso teba.

Standard matla phepelo e bokana ho tloha electrolytic capacitor ho microfarads 10,000, e tletseng-e tsokoang borokho rectifier tsa diodes le gagamalo khutlisetsang la 50 volts otlolohileng jwale le 3a, ho tsoaka (0.5 A). gagamalo regulator ka boeena o 12 volts - 7912 kapa 7812 (KREN8B).

Sebedisa sethusathuto bokana mochini jwalo hloka boemo metsoako ea elektronike ka tsela e joalo e bolelele pakeng ntseng bo eketseha metsoako e ne e le tlaase-tlaase, 'me ho tlosoa ya radiator ka metsi e - kholo ka ho fetisisa. Bakeng sa tsidifatso, ho ke ke molemo ka ho fetisisa ho nka e tloaelehileng ribbed radiators sebaka lekaneng holim, kapa poleiti tšepe.

Mehloli e sebelisa e akaretse gagamalo regulator 12 volts, o dumella ho sebelisa ha bona bakeng sa phepelo ea matla a mefuta e fapaneng ya disebediswa tsa ho le masakana a bolaoa le tshebediso ya TTL kopantswe lipotoloho sea utloahala kapa che, ho akarelletsa le disebediswa tsa ho bakeng sa likoloi tse likoloi.
