Indlela yokwenza isicelo komlawuli ombane volts 12

Njengoko kwiisekethe echazwe umthombo amandla yokukhulisa zokusebenza yemithombo asezantsi amandla ngokufuthi zisetyenziswa volts eziliqela (12-15). Ukuza kuthi ga ngoku, umlawuli volt ombane kakhulu saa ngokubanzi 12 iqwalaselwe nge usebenzisa iiyunithi emithathu-terminal ezihlanganisiweyo. injongo yabo ukuze ufumane ombane imveliso kunye ubukhulu bezinto yangoku yombane. components Main - iziphaluka ezihlangeneyo yi KR142EN8B imveliso yasekhaya kwaye amazwe analogue series MS78hh kunye MS79hh okanye 78hh nje 79hh.

Iintlobo basekhaya angaphandle of ekwenzeni

KR142EN8B Russian unit ezifunekayo (olufinyeziweyo igama KREN8B) ibonelela imveliso ombane eqhelekileyo volts elinambini.

ekwenzeni ngaphandle series ngasentla kufuneka izihionipho ilandelayo: Inombolo nokuba lokuqala (78) ibonisa injongo - imveliso ngoku HIV, kukho inani elingumnqakathi (79) - ombane imveliso elibi. Amanani amabini okugqibela (12 okanye 05) kubonisa imveliso amandla yangoku yombane. Umzekelo: 7912 - IC - 12V ombane alawulayo kunye wokwephuka ezimbi, 7805 - chip - iyunithi enye, volts-5 kuphela yaye a wokwephuka ezintle.

Three-terminal njengoko negama layo liyichaza, uye iziphumo ezintathu ezibonelela uqhagamshelwano isekethe yombane zangaphandle: igalelo, imveliso kunye ngokubanzi. To connect to ( "umhlaba") yezindlu umthombo wamandla isebenzisa imveliso eqhelekileyo. Igalelo kunye ezinjengeetheminali aqhelekileyo asetyenziswa ukuba unikeze i ombane igalelo kunye neziphumo siqala ukusebenza ngomhla izigqibo "yokuphuma" yaye "eqhelekileyo".

I-Regulator ombane 12 volts ziya kusebenza kweli tyala ngesiqhelo, ukuba igalelo yangoku xa imveliso umthwalo eliphezulu ngokuvunywe udlula ubuncinane 2.5 volts. Ixabiso igalelo ubuninzi amandla mayingagqithi volts amathathu. Kwakhona, phawula ukuba ombane ukwanda igalelo inika inzuzo amandla, 12B somfanekiso uqalisa lisenziwa shushu ngako. Ngako oko, kubalulekile ukuba ukuthintela umonakalo ukusetyenziswa echibini ubushushu.

Standard umbane ibandla ukusuka electrolytic capacitor ukuya microfarads 10,000, elizeleyo wave ibhulorho rectifier lobuceducedu kunye ombane reverse 50 volts ngqo yangoku kunye 3A, fuse (0.5 A). Regulator ombane ngokwakhe volts 12 - 7912 okanye 7812 (KREN8B).

Ukusebenzisa izixhobo ndawonye ngomatshini enjalo kufuna ukulungela imeko nezombane ngendlela yokuba ubude phakathi iikhompawundi ukuyinyusa ilelona lisezantsi, kwaye kususwe kwi radiator - ngobukhulu. Sokwehlisa, kungcono ukuthatha umlinganiselo exabe a radiators yommandla umphezulu ezaneleyo, okanye ipleyiti yesinyithi.

Imithombo isicelo ifaka ombane alawulayo volts 12, evumela ukusetyenziswa kwawo kombane lweentlobo ezahlukeneyo izixhobo kunye neebhloko kubulawa kunye nokusetyenziswa TTL ezihlangeneyo iisekethe logic, kubandakanywa izixhobo kwizithuthi ngomatshini.
