Indlela yokufaka isicelo somthetho voltage volts 12

Njengoba amandla izifunda kuchazwe umthombo yokukhulisa umsindo tekusebenta ka ongaphakeme ugesi ngokuvamile asetshenziswa volts eziningana (12-15). Kuze kube manje, lo ziyasatshalalaiswa kakhulu volt voltage Regulator 12 amisiwe usebenzisa amayunithi ezintathu-ukuphela ehlangene. injongo wabo ukuthola ezahlukene okukhipha voltage ubukhulu namandla kagesi. izingxenye Main - izifunda edidiyelwe KR142EN8B ukukhiqizwa ezifuywayo amazwe analogue uchungechunge MS78hh futhi MS79hh noma 78hh nje futhi 79hh.

izinhlobo ezifuywayo angaphandle ka stabilizers

KR142EN8B Russian iyunithi ebalulekile (esifushanisiwe igama KREN8B) ihlinzeka okukhipha voltage ejwayelekile volts nambili.

stabilizers okungenisiwe uchungechunge eziphawulwe ngenhla okunzima ibe namagama ezilandelayo: ngisho inombolo kokuqala (78) ikhombisa inhloso - omuhle okukhipha zamanje, inombolo engalingani (79) - engeyinhle okukhipha voltage. I last Izinombolo ezimbili (12 noma 05) Indlela amandla okukhipha kagesi. Ngokwesibonelo: 7912 - IC - 12V voltage Regulator nge polarity negative, 7805 - chip - iyunithi efanayo, volts 5 kuphela futhi nge polarity omuhle.

Umlawuli Three-ukuphela njengoba kusikisela igama layo, has okukhiphayo ezintathu ezinikeza uxhumano i wesifunda zangaphandle kagesi: okokufaka, okukhipha kanye jikelele. Ukuxhuma umthombo wamandla izindlu ( "umhlaba") isebenzisa okukhipha ezivamile. Okufakwa terminals ezivamile asetshenziselwa ukuphakela voltage input bese okukhiphayo kokuthi abasebenza iziphetho we "ophumayo" futhi "evamile".

Umlawuli voltage 12 volts izosebenza evamile kuleli cala, uma wamanje okokufaka lapho eliphelele elivumelekile umthwalo okukhipha idlula okungenani 2.5 volts. Inani esiphezulu amandla okokufaka kumele singeqi volts amathathu. Futhi, yazi ukuthi voltage okokufaka anda inikeza amandla inzuzo, 12b isimame iqala sishiswa ngakho. Ngakho, kubalulekile ukuba kuvimbele ukulimala ukusetshenziswa ukushisa echibini.

Standard ugesi libuthene kusukela electrolytic capacitor ukuba 10,000 microfarads, full-wave ibhuloho rectifier ka diodes nge voltage reverse volts 50 ngqo wamanje kanye 3A, fuse (0.5 A). voltage Regulator yena 12 volts - 7912 noma 7812 (KREN8B).

Ukusebenzisa ama-apharathasi abuthanela kuso ukuze umshini olunjalo ludinga Positioning yezingxenye electronic ngendlela yokuthi obuphelele phakathi compounds obandayo laliphansi kunawo, futhi ukususwa kurediyetha - ngobukhulu. Ukuze indlu, kungcono ukuthatha ejwayelekile ribbed radiators surface endaweni okwanele, noma ipuleti metal.

Imithombo isicelo sihlanganisa voltage Regulator volts 12, evumela ukusetshenziswa kwabo amandla supply ezahlukene kumadivayisi nemabhuloki ababulawa ukusetshenziswa TTL ihlanganiswe logic izifunda, kuhlanganise nakwamanye amadivaysi for izimoto yezimoto.
