Me pēhea te ki te whiriwhiri i te kōwae mana supply, me te ka ngau nga tuke

Te nuinga (ki te kore te katoa) hokona kai mana rorohiko e huihui i roto i China. O te akoranga, te parau e "China China - ngangare" kore i whakakorea, engari te kounga o te nuinga o enei whakaaro, kia hoatu ai oangé, he iti. Tenei meka Ko kahore tetahi e huna, na maha whakaarahia te pātai o te pehea, ki te whiriwhiri i te supply mana. Ano, kaiwhakanao ara ingoa maha tohu rimurapa e 20 ōrau tauanga uara o nāianei. I roto i te parau tumu, e taea te mohio ki ratou, no te mea i roto i te mata o te whakataetae mākete e mura, he pai mo te oranga tikanga katoa, engari ki ta te kaiwhakamahi ... tonu te reira rawa tirotiro nga raraunga uruwhenua o taputapu me te pai te māramatanga o te āhua o ki te whiriwhiri i te supply mana mo te rorohiko. Ko te aha e tatou i tenei ra, me te ka kōrero tatou.

Ko te wae mana supply i roto i te tahuhu , a te kaiwhakawhiwhi hiko ki nga wae katoa. I roto i te whānui, ko tona mahi tino māmā me kua roa pai faatiti'aifarohia Electrical: whangai tāuru paerewa 220 V AC, me te putanga, ko te hainga tamau ngaohiko - 3, 5, 12, me te körero e rua. Ki te ui tetahi kaitohutohu i te rorohiko taonga te pātai "Me pēhea te ki te whiriwhiri i te supply mana?" Ia, o te akoranga, ka tohutohu te otinga pai, engari tapiritia e kia kia whakakapia te supply katoa 1-2 tau. Ko te tua nui ki e whai whakauaua te tangata, a i roto i te noa tenei. wāhanga ā-whakawhiti supply mana i runga i mutu te wā ki te ū ki te āhuatanga kī (hei tauira, ngā pūnga maroke), na me te reira ki te whakaputaia ketia.

Na, me pehea ki te whiriwhiri i te supply mana? Ko te tohu tuatahi o te pai poraka autaki - tona taimaha. tangi te reira rerekē, engari te mea pono. Whakawhiti Power Supply - he hua, kaua matatini tono hoahoa whai tupato i roto i te whakaminenga. Ki te kitea e tatou he kōwae Hainamana cheap, te poari ara iahiko tāngia e faahitimahuta ona kore noa iho: i runga e soldered te wahi tohua huānga ou'a, a kore e taea te huaina te whakamahana nui. Na reira, ka kōwhiri i kore whakama ki te whakatau tata i te taimaha o te poraka ringa.

mohiotia te tūtohutanga tuarua ki te tangata katoa e kua ake lau he iti, me pehea ki te whiriwhiri i te supply mana. Otiia toe fakaongo ahau: tae noa ki taea hanga reira tikanga ki te kohikohi i te iti "anō" moni ki te hoko i te hua, me te pai-mohiotia kamupene - GlacialPower, Zalman, ohaoha, me ētahi atu e whakarato ana tēnei kōwae mahi pono o te rorohiko rite ona ngā tawhā atu ranei iti iho fekau'aki ki te tika .. Ko te tauira o te ora i konei: i reira e rua mana supply - GlacialPower 450 Watt Codegen 250 Watts. whakarite matou uruwhenua raraunga ... a matau e te katoa he ratou ake pāngarau. Ko te katoa te kaha whakaaturia hoki Codegen me-rārangi 3 me te 5, ko te rite ki te tawhā taua i roto i GlacialPower! He kitea te mutunga - hoko wae Chinese cheap rite taea, engari ki te rāhui mana rua, me te kore atu te whakamahi ratou atu i te tau. I tua atu, tautoko hua parani rerekē "goodies" pērā i te mana tahi maramarama, e te tikanga puku iti faufaa i roto i te mahi.

I roto i ngā pūnaha hou, taka te pikaunga matua i runga i te raina 5 me 3.3V, na ko reira e tika ana ki te whiriwhiri i te kōwae o te nāianei mōrahi o te rārangi (te ake, te pai). Ko te decal ki raraunga uruwhenua, e hoatu tonu enei uara. Ki te he iti iho i te pūtukatuka te kaha o enei rārangi, ka e rapu tatou mo te tauira pai ake.

I mua i te haere ki te toa tūtohutia ki te tātai i te wae te mana supply. Hoki tenei i reira he hōtaka motuhake ranei paetukutuku. Me whakapūtā koe te momo o pūtukatuka, kāri whakairoiro, mahara, a pera atu. I te wa ano mahara e te uara whiwhi ka kia tohu, a kia whiriwhiria i te tauira rite "te uara tatau o + 20%."

Hei whakarāpopoto:

- Tātaitia te kaha hiahiatia;

- whiriwhiri i te supply mana rangatōpū taimaha;

- manatoko e te mana o + 3.3V me + 5V he nui.

I tua atu, ka taea e koe te utu i whakarongo ki te nui o tūhono kaha: ētahi wā tūhono hoki puku pakeke rewenatia katoa e kore he nui a me te whakamahi ki Molex whāurutau, e kore te mea e watea rawa nei.
