Yadda za a yi amfani da mai sarrafa wutar lantarki na 12 volts

Kamar yadda aka ayyana haihuwarka tushen ikon zuwa aiki amplifiers na low ikon kafofin sau da yawa ana amfani da dama volts (12-15). A kwanan wata, mai amfani da ƙarfin lantarki da aka yi amfani dashi mafi yawa 12 volts, ya yi amfani da yin amfani da rassa guda uku. Manufar su shine a samu a fitowar kayan sarrafawa da kuma lantarki. Abubuwan da aka gina sun hada da kwakwalwa na KR142EN8B da gidaje da samfuran su na MC78xx da MS79xx ko kawai 78xx da 79xx.

Lambobi biyu na ƙarshe (12 ko 05) sun nuna girman ƙarfin halin yanzu. Alal misali: 7912 - microcircuit - mai sarrafa wutar lantarki 12V tare da ƙananan polarity, 7805 - guntu - irin wannan sashi, kawai 5 volts kuma tare da tabbatacce polarity.

Saitaccen samfurin kayan aiki guda uku, kamar yadda sunansa ya nuna, yana da nau'i uku waɗanda ke samar da haɗi zuwa hanyar lantarki ta waje: shigarwa, fitarwa da na kowa. Ana amfani da maɓalli na kowa don haɗi zuwa gidaje na wutar lantarki (ƙasa). Ana amfani da tashoshin shigarwa da ƙananan don amfani da wutar lantarki da aka shigar, kuma fitarwa yana fitowa a fitarwa "fitarwa" da "na kowa."

Mai sarrafa wutar lantarki na 12 volts zai yi aiki kullum idan shigarwar yanzu a matsakaicin iyakar haɗakar da aka halatta ya zarce wutar lantarki ta hanyar akalla 2.5 volts. Matsakaicin shigarwar tushe bai kamata ya wuce talatin ba. Bugu da ƙari, la'akari da cewa ƙara yawan wutar lantarki na shigarwa ya ba da damar samun wutar lantarki, mai sauƙi 12V yana fara zafi a lokaci guda. Saboda haka, don hana lalatawa, wajibi ne don yin amfani da hasken zafi.

Standard samar da wutar lantarki da aka harhada daga electrolytic capacitor zuwa 10,000 microfarads, cikakken-kalaman gada rectifier na diodes tare da wani kuma baya da irin ƙarfin lantarki na 50 volts kai tsaye halin yanzu da kuma 3A, da fis (0.5 A). Mai sarrafa wutar lantarki kanta shine 12 volts - 7912 ko 7812 (KREN8B).

Yin amfani da irin wannan na'ura don aiki da kayan haɗuwa, ana buƙatar sanya kayan aikin lantarki don haka tsawon tsakanin haɗin haɗakarwa shine mafi ƙanƙanci kuma cirewar radiator shine mafi girma. Don sanyaya, ya fi dacewa don ɗaukar radiators masu kyau tare da isassun wuri, ko faranti na karfe.
