Sida loo codsado jaangooyaha danab a 12 volts

Sida awood il wareeggeedii qeexay in Sammeecado hawl ah ilaha awooda yar yahay inta badan waxaa loo isticmaalaa in dhowr volts (12-15). Si aad u taariikhda, inta badan si weyn loo faafin danab volt jaangooyaha 12 qaybiyay isticmaalaya a unug isku dhafan saddex-terminal. Ujeedadoodu waa in ay u hesho danab a saarka kala duwan iyo baaxadda hadda korontada. Tiirarka ugu muhiimsan - wareeggeedii dhafan waa KR142EN8B soo saarka gudaha iyo analogues taxane keeno MS78hh iyo MS79hh ama 78hh iyo 79hh.

noocyada gudaha iyo dibadda ee xasiliya

KR142EN8B Ruush unit muhiim (gaabiyo magaca KREN8B) waxay bixisaa danab a saarka caadiga ah ee laba iyo toban volts.

xasiliya laga keeno taxane sheegnay leeyihiin tilmaamood ee soo socda: tirada xataa hore (78) tusinaysaa ujeedada - saarka wanaagsan ee hadda jirta, tiro kisi ah (79) - a danab saarka xun. Labada lambar ee ugu dambeeya (12 ama 05) waxay muujinaysaa awoodda wax soo saarka ee hadda korontada ah. Tusaale ahaan: 7912 - IC - 12V jaangooyaha danab la polarity negative, 7805 - chip - unit ka mid ah, kaliya 5 volts iyo polarity wanaagsan.

jaangooyaha Saddex-terminal sida ay magaca soo jeedinaya, ayaa saddex natiijo in ay bixiyaan xiriir si circuit dibadda koranto: talooyin, wax soo saarka iyo guud. In ay ku xidhmaan guryaha il awoodeed oo ah ( "dhulka") wuxuu isticmaalaa wax soo saarka caadi ah. The talooyinka iyo boosteejada caadiga ah waxaa loo isticmaalaa si ay ugu deeqdo danab talooyin iyo wax soo saarka ee aan is ka shaqeeya gabagabadii ah "exit" iyo "caadi ah".

jaangooyaha danab 12 volts shaqayn doonaa sida caadiga ah ee kiiska, haddii la gelin hadda marka saarka load oggol ugu badan ee ka badan ugu yaraan 2.5 volts. Qiimaha aqbasho awoodda ugu badan waa in aan ka badnayn soddon volts. Sidoo kale, la soco in danab ku talooyinka kor u bixisaa faa'iido xoog, 12b stabilizer bilaabaa inuu hore loo kululayn jiray. Iyadoo la raacayo, waxaa lagama maarmaan ah si looga hortago in dhaawac isticmaalka saxanka kulaylka.

Standard korontada waxaa soo ururay oo ka electrolytic capacitor in 10,000 microfarads, ruxruxo buuxa rectifier buundada of dioska- la danab a dambe ee 50 volts toos ah hadda iyo 3A, fiyuuska (0.5 A). danab jaangooyaha qudhiisu 12 volts - 7912 ama 7812 (KREN8B).

Isticmaalka qalab ku soo ururay, waayo, mashiinka noocan oo kale ah u baahan tahay Positioning ka kooban elektarooniga ah ee sidan oo kale in dhererka u dhexeeya xeryahooda kordhaya ahaa kii ugu hooseeyey, iyo ka saarista hiitarka ah - ugu weyn. Waayo, qaboojinta, waxaa fiican in ay qaataan a hiitarka Heerka godgodan ee bedka ku filan, ama saxan bir ah.

Ilo codsanaya daro jaangooyaha danab 12 volts, kuu ogolaanaya in ay isticmaalka loogu talagalay korontada ee noocyada kala duwan ee qalabka iyo blocks toogasho ah iyadoo la isticmaalayo mid ah TTL dhafan wareeggeedii macquulka ah, oo ay ku jiraan qalabka baabuurta baabuurta ah.
