Za'a iya saita girman halin yanzu don iyakance fitarwa na halin yanzu, kullun kullun, da fitilun cajin baturi.
Tare da nasa kayan aikin anti-baya-gudanarwa, babu buƙatar ƙara diode mai gujewa baya lokacin cajin baturi.
Umarnin don amfani
1. An yi amfani da shi azaman ƙirar ƙararrawa ta yau da kullun tare da kariya ta yau da kullun
Yadda ake amfani da:

(1) Daidaita ma'aunin wutar lantarki na CV na potentiometer ta yadda ƙarfin fitarwa ya kai ƙimar ƙarfin lantarki da kuke so
(2) Auna fitarwa na gajeren zangon halin yanzu tare da tasha na yanzu 10A multimeter (kai tsaye haɗa alkalan biyu zuwa ƙarshen fitarwa), kuma daidaita madaidaicin madaidaicin CC na yanzu don sa fitarwa na yanzu ya kai ga ƙimar kariya ta yau da kullun. . (Misali darajar halin yanzu da na'urar multimeter ke nunawa ita ce 2A, to, babban halin yanzu zai iya kaiwa 2A kawai lokacin da kake amfani da tsarin, kuma alamar wutar lantarki akai-akai na ja yana kunne lokacin da na yanzu ya kai 2A, in ba haka ba mai nuna alama shine. kashe)
Lura: Lokacin da aka yi amfani da shi a cikin wannan yanayin, saboda fitarwa yana da juriya na samfurin yanzu na 0.05 Ohm, za a sami raguwar ƙarfin lantarki na 0 ~ 0.3V bayan haɗa nauyin, wanda shine al'ada! Wannan faɗuwar wutar lantarki ba kayanka bane ya saukar da ita, amma ƙasa zuwa juriyar samfur.

2. Yi amfani azaman cajar baturi
Ba za a iya amfani da tsarin ba tare da aiki na yau da kullum ba don cajin baturi, saboda bambancin matsa lamba tsakanin baturi da caja yana da girma sosai, yana haifar da cajin da ya wuce kima, yana haifar da lalacewar baturi, don haka ya kamata a yi amfani da baturin a farkon na'urar. cajin na yau da kullun, lokacin da ake caji zuwa wani ɗan lokaci, ta atomatik tana juyawa zuwa cajin wutar lantarki akai-akai.

Yadda ake amfani da:
(1) Ƙayyade ƙarfin wutar lantarki da cajin baturin da kuke buƙatar caji; (Idan ma'aunin baturi na lithium shine 3.7V/2200mAh, to, ƙarfin caji mai iyo shine 4.2V, kuma babban cajin yanzu shine 1C, wato, 2200mA)
(2) A ƙarƙashin yanayi mara nauyi, multi-mita yana auna ƙarfin fitarwa, kuma ana daidaita ƙarfin ƙarfin wutar lantarki akai-akai don sanya ƙarfin fitarwa ya kai ga ƙarfin cajin iyo; (Idan ka yi cajin baturin lithium 3.7V, daidaita ƙarfin fitarwa zuwa 4.2V)
(3) Auna fitarwa na gajeren zangon halin yanzu tare da tasha na yanzu na mita 10A mai yawa (kai tsaye haɗa alkalan biyu zuwa ƙarshen fitarwa), kuma daidaita madaidaicin ma'auni na yanzu don sa fitarwa na yanzu ya kai ga ƙimar caji na yanzu da aka ƙaddara;
(4) Tsohuwar caji na yanzu shine sau 0.1 na cajin halin yanzu; (A hankali a hankali baturin da ke cikin cajin yana raguwa, sannu a hankali daga cajin na yau da kullun zuwa cajin wutar lantarki akai-akai, idan an saita cajin halin yanzu zuwa 1A, to idan cajin halin yanzu bai wuce 0.1A ba, hasken shuɗi yana kashe, kore. haske yana kunne, a wannan lokacin ana cajin baturi)
(5) Haɗa baturin kuma yi cajin shi.
(Mataki na 1, 2, 3, 4 sune: ƙarshen shigarwa yana haɗa da wutar lantarki, kuma ƙarshen fitarwa ba a haɗa shi da baturi.)
3. An yi amfani da shi azaman babban iko LED akai direba na yanzu
(1) Ƙayyade ƙarfin aiki na yanzu da babban ƙarfin aiki da kuke buƙatar fitar da LED;
(2) Ƙarƙashin yanayi mara nauyi, mita mai yawa yana auna ƙarfin fitarwa, kuma ana daidaita ma'aunin wutar lantarki akai-akai don sanya ƙarfin fitarwa ya kai ga babban ƙarfin aiki na LED;
(3) Yi amfani da na'urar mita 10A da yawa don auna fitarwa na gajeren lokaci na halin yanzu, da daidaita madaidaicin ma'aunin ƙarfin halin yanzu don sanya fitarwar yanzu ta kai ga ƙaddarar LED mai aiki na yanzu;
(4) Haɗa LED ɗin kuma gwada injin.
(Mataki na 1, 2, da 3 sune: an haɗa shigarwa zuwa wutar lantarki, fitarwar ba ta haɗa da hasken LED.)
