Mau nota i runga i te kōwhiri i te supply mana whakawhiti?

1) Ki te whakanui i te tika o te supply mana whakawhiti, whakaaro tatou kaiwhakamahi whiriwhiri he kōwae e kua he whakatauranga o te 30% atu te mana i te hiahia tūturu. Hei tauira, ki te me te pūnaha he pūtake 100W, whakaaro tatou e ngā kaiwhakamahi te kōwhiri i te SPS ki 130W o te mana putanga atu ranei. Na roto i te mahi tenei, ka taea e koe tōtika i näianei i te tika o te SPS i roto i to koutou pūnaha.

2) Me hoki tatou ki te whakaaro e pā ana ki ambient pāmahana o te SPS me mehemea reira he pūrere atu hoki faaore i te wera. Ki te te te mahi te SPS i roto i te taiao pāmahana teitei, e ti'a ia tatou ki te hanga i etahi derating ki te mana putanga. Ka taea te kitea te ānau derating o "pāmahana ambient" versus "mana putanga" i runga i to tatou pepa spec.

3) kōwhiri mahi e hāngai ana i runga i to koutou tono:

* Mahi Parenga: Neke atu i te Ngaohiko Protection (OVP), Neke Temperature Parenga (OVP), Neke atu i te Protection Utaina (OLP), me ētahi atu

* Mahi Taupānga: kïia e Taumahi (Power pai, Power Rahu), Mana Mamao, Mamao Tārewa, a etc.

* Special mahi: Whakatika Power Factor (PFC), Puna Hiko (UPS) mahi.

He aha te mea whakaritenga kawenga iti i te spec?

He etahi whakaritenga iti rawa-kawenga i runga i maha-putanga kai mana. Koa te pānui i te whakatakotoranga ki te aroaro o te tuatahi tūhono ki te kawenga. I roto i te tikanga ki te tuku i te supply mana ki te mahi tika, te hiahiatia he kawenga iti mo ia putanga, atu, ka hei te taumata ngaohiko whakaputa ngā kātakí iu waho ranei ranei. Tirohia ki " ngā nāianei " i roto i te whakatakotoranga rite whakaaturia i roto i te ripanga i raro nei: Channel 1 titau te 2A iti-kawenga; teihana 2 titau 0.5A; Channel 3 titau 0.1A; E kore e Channel 4 Me tetahi iti-kawenga.

He aha i te supply mana puru ana ki raro i roto i te mahi, me te i muri i tahuri i te reira atu, Ka taea e ahau tīmata anō ano te supply mana?

I roto i te whānui reira e rua huru e ka meinga te supply mana ki te tutakina iho. Ko te tetahi tuatahi ko te faaitoitoraa o te mo-utanga-tiaki (OLP). Hei mahi ki tenei āhuatanga, e faaite te whakanui ake tatou te whakatauranga o te mana putanga ranei te whakakē i te pūwāhi OLP. Ko te tetahi tuarua ko te faaitoitoraa o te tiaki i runga i-pāmahana (OTP) ina tae te pāmahana ā-te uara mua whakaritea-. ka tuku i te SPS tomo aratau tiaki me te tutakina iho katoa o enei tikanga. I muri e nekehia atu enei tikanga, ka hoki ki noa kia te SPS.

He aha te mea PFC?

Power Factor Whakatika (PFC) ko ki te whakapai ake i te ōwehenga o te kaha kitea ki te mana tūturu. Ko te take mana, ko te a tawhio noa 0.4 ~ 0.6 i roto i te tauira PFC-kore. I roto i te tauira ki PFC ara iahiko, ka taea e te take mana tae i runga 0,95. Ko nga tātai tātai e whai ake: kitea Power = Tāuru Ngaohiko x Tāuru nāianei (VA), Power Real = Tāuru Ngaohiko x Tāuru nāianei x Power Factor (W).
Mai i te wāhi o te tirohanga o te taiao hoa, me te whakato te mana ki te whakaputa i te mana i te mea teitei ake i te mana kitea i roto i te tikanga ki te āta whakarato hiko. Tautuhi te whakamahi tūturu o te hiko e te mana tūturu. Mā te take mana, ko te 0.5, me te whakato te mana ki te whakaputa i neke atu i te 2WVA ki makona 1W whakamahinga mana tūturu. I te anga ke, ki te ko te take mana 0,95, te tipu te mana anake me ki te whakaputa atu i te 1.06VA ki te whakarato 1W mana tūturu, ka waiho te reira i atu whai hua i roto i te pūngao whakaora ki PFC mahi.
Ka taea te wehea Active topologies PFC ki kotahi-atamira kaha PFC me rua-atamira kaha PFC, te rerekētanga he whakaaturanga rite i roto i te ripanga i raro nei.

He aha te mea te rerekētanga i waenganui i -V me COM e Kua tohua i te taha putanga?

- COM (COMMON) te tikanga whenua noa. kite koa i raro:

putanga kotahi: Positive pou (+ V), pou tōraro (-V)

putanga Maha (whenua Common): pou takatika (+ w1, + V2), pou tōraro (COM)

Ko te whenua putanga (GND) me te anga whenua (FG) ko te wāhi kotahi i roto i toku pūnaha, ka taea te whakamahi kai BST mana i roto i taua pūnaha?

Ae. Mai e hangaia matou hua e hāngai ana i runga i wehe ariā, ka waiho kore raruraru e te whenua putanga (GND) me te anga whenua (FG) ko te wāhi taua i roto i to koutou pūnaha. Ko, kia EMI kia pā i tenei hononga.

I roto i te mahi o to koutou supply mana, i reira he etahi nāianei leakage i runga i te take. He noa tenei? E kino ia tenei nāianei leakage te tinana tangata?

Nā ki te titauraa o EMI, i reira ka kia te tahi mau pūnga iahiko Y i waenganui i te rārangi, me te kūpapa ki te FG (take) ki te whakapai ake EMC. ka meinga ēnei pūnga iahiko Y etahi rere nāianei leakage i raina kūpapa ranei ki te take (tikanga ka take kia hono ki te whenua whenua). Hei tauira, IEC-60950-1 titau e kia kia iti iho i te 3.5mA mō taputapu IT tenei nāianei, na waiwai kore te nāianei leakage kitea koutou i runga i te take ka kino ia te tinana tangata. Ka whakaoti hononga Totonu ki whenua Papatūānuku te raruraru o nāianei leakage.

Hoki etahi hiahia, ko reira taea ki te whakaiti i te haruru o te tahi?

Kei te pā hāngai ngangau ki te tahi i te mea hanga ki te supply te mana. E tukupu te airflow o te tahi tikanga whakaiti i te kaha tohanga wera. Ka whakaawe hoki te reira i te tika o nga hua. I tua atu, tautuhia airflow iti o te pā e Safety Organization, a ka hiahiatia he konga haumaru kia ki te whakamahi i te mea powhiriwhiri hou. Ko te tikanga, ka whiriwhiri tatou i te supply mana e tika ana, e kore te mea e tika ana tahi, ki te he wattage raro 150W. I waenganui 150 ~ 500W, he wātea tahi me te fanless hua e rua. Runga ake 500W, e hiahiatia ana he tahi te.

He aha te mea te pūtāhui o ngā hua BST?

BST tuku 2 yeas pūtāhui

Ki te whai kounga raruraru te hua i roto i te wā pūtāhui, ka whakarato matou ratonga tiaki; E kore e waiho matou kawenga mō te kaipuke, me te tāuta utu i pau i ta'etotonu tāutanga, faaino i tānoanoa ki te wae ranei.

Ki te tetahi raruraru i roto i te whakamahi i, Ka taea e whakapā noa tatou koutou, ka meatia e matou i to tatou pai ki te te āwhina ki a koutou.
