Njengamamodeli abuyekeziwe ochungechunge lwe-FOCUS, kumayunithi abuyekeziwe ochungechunge lwe-PRIME ikhebula lamandla elikhulu lenziwe ngomluko enayiloni, futhi wonke amanye anomklamo oyisicaba.
Wonke amageji ezintambo ajwayelekile angu-18 AWG.
Umklamo, isakhiwo sangaphakathi
Izingxenye zangaphakathi zipholiswe yisiphepho esingu-13525 mm HongHua HA12H135F-Z ngokususelwe kubheringi ye-hydrodynamic. Ijubane lokuzungeza abalandeli lingu-2300 rpm.
Qaphela ukuthi izinsiza zamandla ze-Seasonic PRIME Titanium zokukhishwa kwangaphambilini engike ngabhekana nazo zisebenzise ukuguqulwa okuhamba kancane kwe-HA13525M12F-Z fan (1800 rpm).
Isakhiwo sangaphakathi sibonisa isakhiwo esijwayelekile seplathifomu ye-Seasonic PRIME (phakathi kwamamodeli esiwabuyekezile, ukunikezwa kwamandla kusekelwe enguqulweni eguquliwe βyeplatinamuβ yale nkundla. ).
Ngokufanelekile, sinenkundla yesimanje esekelwe ku-LLC resonant topology enokuqina kwamandla kagesi ngamunye kanye nokulungiswa kwezinto zamandla asebenzayo.
Ibhodi lokuguqula i-DC/DC litholakala phakathi kwephaneli yesixhumi esiyimojuli kanye nebhodi lendodakazi elinesilawuli sokupholisa. Okunye okubonakalayo esithombeni ama-solid-state capacitor ashelelayo ebhodini ngezixhumi eziyi-modular.
Elinye ibhodi lendodakazi eline-SRC/LLC+SR Champion Micro CM6901 yesilawuli chip litholakala ngemuva kwebhodi elilawula ukusebenza kwesistimu yokupholisa.
I-chip ye-Weltrend WT7527V supervisor itholakala ebhodini lendodakazi eceleni kwecala.
Isihlungi sokufaka ebhodini lesifunda eliphrintiwe eliyinhloko sihlanganisa isethi ejwayelekile ngokuphelele yama-coke amabili ajwayelekile, i-capacitor CX, ama-capacitor amane CY kanye ne-varistor.
Kukhona nezinto zokuhlunga ngaphansi kwesikrini ekufakweni kwentambo yamandla: kukhona ipheya yama-capacitor CX ne-CY, kanye ne-fuse.
Okokufaka, ama-electrolytic capacitor amabili akhiqizwa yinkampani yaseJapan i-Rubycon enenani eliphelele le-1030 ΞΌF asetshenziswa. Ngokweqile, umphumela omuhle kakhulu amandla e-microfarad we-input capacitor, elingana ngezinombolo namandla okukhiphayo kuma-watts - futhi leli zinga lidlulwa kakhulu ku-PRIME TX.
Ekuphumeni, kusetshenziswa ama-electrolytic capacitor akhiqizwa i-Rubycon ne-Nichicon, kanye nama-solid state capacitor afihlwe ngaphansi kwerediyetha yokupholisa.
Ngokuvamile, njengoba kulindelekile, asikho nesincane isikhalazo mayelana nezingxenye ezisetshenzisiwe noma ikhwalithi yokwakha.
Indlela yokuhlola
Indlela yokuhlola eyamukelwe i-3DNews ichazwe ku , okunconywa ukufunda ukuze uqonde ukusebenza kwamandla kagesi wekhompiyutha kanye nezici zabo ezibaluleke kakhulu. Bheka kuwo ukuze uthole ukuthi kungani lokhu noma leyo ngxenye okukhulunywe ngayo ekubuyekezweni isebenza kanjani, nokuthi ungayihumusha kanjani imiphumela yokuhlolwa.
Imiphumela yokuhlolwa
Ukusebenza kahle kwe-Seasonic PRIME TX-750 okukalwe ngesikhathi sokuhlolwa kubonisa imiphumela ephezulu elindelwe.
Ngokwengxenye, izibalo ezinjalo eziphakeme ziwumphumela wephutha lokulinganisa le-wattmeter yasendlini, ebukela phansi amandla "aphuma kusokhethi" emithwalweni ephakathi nendawo futhi esindayo.
Eduze kwamanani asebenza kahle kakhulu kuzoba yimiphumela yombiko wesitifiketi se-80 PLUS se-Seasonic SSR-750TR (ngamandla angu-10/20/50/100%, ukusebenza kahle kwe-91,71/93,85/94,59/92,89% kwarekhodwa, ngokulandelana). Le miphumela itholwe ekuhlinzekweni kwe-115 V, ngakho-ke ukusebenza kahle kufanele kube phezulu ekunikezeni okungu-230 V.
Ngokusho kwegrafu yomkhiqizi, kunethiwekhi ye-230 V iyunithi ithola ibhonasi esebenza kahle kakhulu: ngamandla aphelele, ukusebenza kahle kuqhathaniswa nokuphakama kwenethiwekhi ye-115 V, futhi ekuphakameni kudlula i-97%.
Uma kuqhathaniswa namamodeli ochungechunge lwe-FOCUS, umuntu angakwazi ukuqaphela isivinini sokuqala esiphezulu kakhulu sefeni yokupholisa (ngaphezu kuka-800 rpm), enxeshezelwa ngokuyigcina icishe ibe namandla aphelele. Ngaphansi komthwalo ogcwele, isivinini se-impeller sidlule kancane ku-900 rpm.
Lapho imodi yokupholisa eyingxube yenziwe yasebenza, ifeni yaqala kuphela ngemva kokufinyelela amandla angu-70%. Kuleli qophelo nangale kwalokho, ijubane lokuzungeza i-impeller lalicishe lifane kuzo zombili izindlela zokusebenza zesistimu yokupholisa. Kodwa-ke, kukhona impukane encane emafutheni lapha: lapho i-fan iqala (kokubili lapho ukunikezwa kwamandla kuvuliwe, futhi uma fan icushiwe ngemva kokungasebenzi kwimodi ye-hybrid), iqala ngesivinini esigcwele, futhi ngomzuzwana. noma ezimbili kuvela ukuthi zizwakala impela.
Nakuba ngesikhathi sokuhlola asizange sibone ukuvula/ukuvalwa kwefeni njalo kumodi exubile, uma nje singacabangela ukusebenzisa isistimu yokupholisa ifeni ehlala ivuliwe - ayizwakali ngaphansi kwanoma imuphi umthwalo.
Izici zomthwalo weyunithi, nakuba zibonisa amapharamitha ahloniphekile ahambisana nezithembiso zomenzi, zisadumaza kancane: emithwalweni eminingi, ukuphambuka kwawo wonke ama-voltage kudlula kancane i-1% yenani legama - nakuba ngokuzethemba, umkhawulo omuhle, ulingana phakathi kuka-2% wokubekezelelana. Ake sikukhumbuze ukuthi umkhiqizi uthembise okungaphezu kuka-1% emigqeni engu-3 no-5 V, futhi akukho ngaphezu kuka-2% we-voltage engu-12 V - kanye no-0,5% lapho umthwalo ushintsha emigqeni ngayinye. Iyunithi ihlangabezane nalezi zimiso, okuhlanganisa ukushintshashintsha kwamandla kagesi okungengaphezu kuka-0,5% lapho umthwalo ushintsha.
Kodwa-ke, isibonelo salokhu osekushiwo ngenhla kwe-ASUS ROG Thor 1200W Platinum, ehlobene ekwakhiweni, enokuqina okuhle kwawo wonke ama-voltages, siphakamisa ukuthi, cishe, besinebhadi elincane ngesifanekiso.
Ku-voltage engu-12 V kumafrikhwensi aphansi, ububanzi be-ripple obuphakeme bucishe bube ngu-20 mV (ene-120 mV evumelekile), futhi uma imvamisa ephezulu akukho kushaya ngamandla. Ku-voltage engu-5 V, ububanzi be-ripple buncane kuwo womabili amaza aphansi naphezulu.
okutholakele
Ukunikezwa kwamandla kaSeasonic PRIME TX-750 kubonise imingcele emihle kakhulu: ukuqina kwamandla kagesi okuhloniphekile, ububanzi obuncane bokugeleza nokusebenza kahle kakhulu. Imodeli futhi inesethi ecebile kakhulu yempahla kanye nobude bewaranti yerekhodi.
Phakathi kwamaphutha, singaqaphela kuphela amabala athile ekusebenzeni kwesistimu yokupholisa: isiqalo esinomsindo sefeni kanye nesivinini esithe xaxa (nakuba singabangeli ukungakhululeki okuncane kwe-acoustic) lapho usebenza ngemithwalo ephansi nephakathi. Futhi-ke, intengo ikude kakhulu nokufinyeleleka emhlabeni wonke.
