Me pēhea te ki te tono i te regulator ngaohiko 12 volts

Ka rite ki te mana iahiko tautuhi puna ki amplifiers whakahaere o puna mana iti maha e whakamahia i roto i te maha volts (12-15). Ki te rā, te wae ngaohiko ngaohiko regulator tino whānui horahia 12 whirihora te whakamahi i te wae integrated toru-kāpeka. Ratou whakaaro, ko te ki te whiwhi i te ngaohiko putanga rerekē me te nui o te nāianei hiko. wāhanga matua - ngātahi iahiko ko KR142EN8B production kāinga me te raupapa analogues kawemai MS78hh me MS79hh ranei tika 78hh me 79hh.

momo kāinga, me te ke o stabilizers

KR142EN8B Russian kōwae wāhi (haapotohia ingoa KREN8B) whakarato te ngaohiko whakaputa noa o ma rua volts.

stabilizers kawemai raupapa i faahitihia i te iku'anga e whai ake nei: te tau tae noa tuatahi (78) E whakaatu ana te whakaaro - pai nāianei putanga, he tuhene (79) - he ngaohiko tōraro putanga. Ko te mati e rua whakamutunga (12 ranei 05) tohu o te mana putanga o te nāianei hiko. Hei tauira: 7912 - IC - 12V ngaohiko regulator ki wehenga kino, 7805 - maramara - te wae taua, 5 anake volts me ki te wehenga tawhiti pai.

regulator E toru-kāpeka tona ingoa kōrero rite, e toru ngä e whakarato hononga ki te ara iahiko hiko waho: tāuru, putanga, me te whānui. Hei te hono ki te whare pūtake mana ( "whenua") whakamahi i te putanga noa. Ko te tāuru me terminals noa e whakamahia ana ki te homai i te ngaohiko tāuru me te putanga kia mahi tatou i runga i nga whakatau o te "putanga" me "noa".

Ko te regulator ngaohiko ka mahi te tikanga 12 volts i te take, ki te te nāianei tāuru ina nui te mōrahi putanga kawenga whakaaetia i te iti rawa 2.5 volts. e kore e nui te uara o te tāuru mana mōrahi e toru tekau volts. Hoki, mōhio e whakarato ana i te ngaohiko tāuru nui haere te mana taonga, haamata 12B stabilizer ki te hana. Nä, he mea e tika ana ki te ārai kino ki te whakamahi o te totohu wera.

Paerewa supply mana huihui te i te -hiko pūnga ki 10,000 microfarads, he poipoi-tonu piriti rectifier o te p ki te ngaohiko whakamuri o 50 volts hāngai nāianei, me te 3A, te wiki (0.5 A). regulator ngaohiko ia 12 volts - 7912 ranei 7812 (KREN8B).

Mā te whakamahi i te taputapu huihui hoki te mīhini taua titau kitea te wāhanga hiko i roto i te ara taua e ko te roa i waenganui i whakapuru pūhui te raro, me te tango o te whakamahana - nui rawa. Hoki tautauā, he reira pai ki te tango i te paerewa rarai radiators o te horahanga mata rawaka, ranei pereti konganuku.

Rauemi tono komokomo ngaohiko regulator 12 volts, taea ratou te whakamahi mō te supply te mana o ngā momo rerekē o ngā pūrere me poraka e mahi ki te whakamahi o te TTL integrated iahiko arorau, tae atu ki ngā pūrere hoki waka automotive.
