Ungayikhetha njani iPDU?

Umgangatho wemali

I-1) Umhlanganisi: uqhelene nezixhobo ezikwigumbi lekhompyuter, ukudibanisa okupheleleyo, ukuhlaliswa ngokubanzi, kunye nexabiso eliphezulu.

I-2) Abavelisi bezixhobo: Iyakwazi ukufanisa ngokuchanekileyo ifom ye-jack kunye neeparitha zamandla kunye nokuthengiswa kwezixhobo ezifana neeseva, ii-routers, utshintsho, njl., kunye nephakheji kunye nokuhlalisa kunye nezixhobo, kwaye ixabiso liphakathi.

3) Umzi-mveliso weKhabhinethi: Umzi-mveliso wekhabhinethi yifektri yentsimbi, kwaye ayinazo iziqinisekiso zokuvelisa izixhobo zombane, ngakumbi i-OEM yomzi-mveliso wekhabhathi.Ulawulo lomgangatho kunye neenguqu zemveliso zihluphekile, ixabiso liyabhida, iintlanzi kunye neentlanzi zixutywe, kwaye kunzima ukuchonga, kodwa ukufakwa kweLula.Pakisha kwaye uhlale kunye nekhabhinethi.

I-4) Ababoneleli bombane abaqeqeshiweyo: njengeekhabhathi zokusasaza amandla entloko yekholomu kunye nabathengisi be-PDU abaqeqeshiweyo, unokufumana isikhokelo sobuchule kunye noncedo, uhlengahlengiso oluguquguqukayo, ukucwangciswa okusemgangathweni, ukhuseleko oluphezulu, kunye nexabiso eliphantsi, kufuneka nje uzinziswe ngokwahlukileyo.

I-5) Iimpawu zasekhaya kunye nezangaphandle: isiqinisekiso sophawu lwangaphandle sigqityiwe, ukuqinisekiswa komgangatho;kodwa ixabiso liphezulu, ixesha lokuhambisa lide, ngokuqhelekileyo lithatha iiveki ezi-6-8, ifom ye-socket ayiyodwa, kwaye ukuhambelana neplagi yezixhobo ihluphekile, iyimveliso yemodeli eqhelekileyo, kwaye ayikwazi ukwenziwa ngokwezifiso.;Isiqinisekiso esipheleleyo samacandelo ohlobo oluphezulu lwasekhaya, iziqinisekiso ezipheleleyo zefektri, ukuhlolwa kwemveliso enye, ixabiso eliphakathi (elilingana ne-1/3~1/2 yeempawu zamazwe ngamazwe), inkonzo epheleleyo, kunye nenqanaba eliphezulu lokwenziwa kweemveliso;ngelixa iimpawu zasekhaya eziphantsi : Ukuqinisekiswa kwamacandelo akuphelelanga kwaye uzinzo lwekhwalithi aluphezulu.Uninzi lwazo ziimveliso ezidityaniswe ziifektri ezincinci eziqikelelwayo.Lo mzi-mveliso awunazo iimfaneleko okanye usebenzisa iimfaneleko zabanye.Iiparamitha zisiphithiphithi kwaye ukuziphatha kunesibindi.Ezinye zisenokwenziwa ngokwezifiso, kwaye ixabiso liphantsi kakhulu.Endaweni yokusebenzisa le PDU, kungcono ukusebenzisa umtya wamandla oqinisekileyo wesiphelo esiphezulu.

Ukucwangcisa kunye nokukhetha

Kwiibhidi ezininzi zegumbi lekhompyuter, iPDU ayidweliswanga njengomgca owahlukileyo njenge-UPS, ikhabhinethi yentloko yekholamu, ikhabhathi kunye nezinye izixhobo, kunye neeparamitha ezifunekayo zePDU nazo azicacanga kakhulu, kwaye ezinye zide zibonise umtya wamandla, oya kubangela okukhulu. ingxaki kumsebenzi wamva.: Oko kukuthi, ukungakwazi ukuhambelana nezinye izixhobo, unikezelo lwamandla olungekho mgangathweni, ukunqongophala okukhulu kohlahlo lwabiwo-mali, njl njl. Esona sizathu siphambili salo mcimbi kukuba omabini amaqela kwibhidi kunye nethenda ayicacanga malunga nendlela yokumakisha iPDU efunekayo?Nantsi indlela elula kuwe:

I-1) Amandla esiphaluka sesebe lokusasazwa kwekhabhinethi yentloko yekholomu + umda wokhuseleko = inani lamandla e-PDU kulo mgca;

2) Inani lezixhobo kwikhabhinethi + i-margin yokhuseleko = inani leejekhi zazo zonke ii-PDU kwikhabhinethi.Ukuba kukho imigca emibini engafunekiyo, inani le-PDU kufuneka liphindwe kabini ngokweeparamitha.

3) Ukusasaza izixhobo eziphezulu zamandla kwii-PDU ezahlukeneyo kangangoko kunokwenzeka ukulinganisa okwangoku kwisigaba ngasinye;

I-4) Ipatheni yomngxuma we-PDU ilungiselelwe ngokusekelwe kwiiplagi zesixhobo ezineentambo zamandla azikwazi ukuhlukana.Emva kokuba iiplagi zesixhobo ezineentambo zamandla ezinokuthi zihlulwe azihambelani, intambo yamandla inokutshintshwa ukusombulula ingxaki;

5) Ukuba ukuxinana kwezixhobo kwikhabhinethi kuphezulu, iPDU kufuneka ifakwe ngokuthe nkqo kunye neejacks ezininzi.Ukuba ukuxinana kwezixhobo kwikhabhinethi kuphantsi, iPDU kufuneka ifakwe ngokuthe tye kunye neejack ezimbalwa.Okokugqibela, uhlahlo lwabiwo-mali olwahlukileyo kufuneka lunikezelwe kwi-PDU ukunqanda ukunqongophala okukhulu kohlahlo lwabiwo-mali.

Iindawo zokuthenga

1) Khetha imveliso ehambelana nawe ngokwemeko yakho ethile;

2) Khetha iimveliso ezivela kubavelisi abaqhelekileyo (ngokuqinisekileyo, abanye abavelisi banokuba ngabavelisi abaqhelekileyo, kodwa i-PDU ayinakuba yimveliso yabo ebalaseleyo, ngoko kufuneka uqaphele xa ukhetha. Nangona ugqirha wezilwanyana ungugqirha, awukwazi ukucinga ukuba ixesha elide. njengoko engugqirha, ukwangugqirha odumileyo.

3) Urhulumente unokuhlolwa okufanelekileyo komgangatho kunye nesiqinisekiso seemveliso ezahlukeneyo.Xa ukhetha iimveliso zePDU, kufuneka uqale ujonge iziqinisekiso zomenzi, kwaye emva koko ujonge ukuqinisekiswa komgangatho wemveliso.Kukhuselekile ukukhetha iimveliso eziqhelekileyo;

4) Emva kokushwankathela oku ngasentla, emva koko uqonde inkonzo emva kokuthengiswa kweemveliso ezinxulumeneyo (kungakhathaliseki ukuba imveliso ilungile kangakanani na, akukho mntu unokuqinisekisa ukuba ayiyi kwaphulwa, ngoko ke inkonzo emva kokuthengisa ingumba ophambili; kwaye khumbula. ukuba inkonzo emva kokuthengisa ayikwazi ukuthetha kuphela ngegama, kuyacetyiswa ukuba ithathe ingcambu. , uyibeke ngamagama);

5) Xa ukhetha i-PDU, kufuneka uqale ujonge iziqinisekiso zomenzi kunye namaxwebhu esiqinisekiso sefektri ukuqinisekisa ukuthembeka kokucubungula;okwesibini, jonga iziqinisekiso zemveliso, amaxwebhu okuvavanya, iincwadana zemveliso, iiplates zokuchongwa, njl njl ukuqinisekisa imveliso.eqhelekileyo.I-PDU yimveliso elungiselelwe ukuhanjiswa kwamandla kwigumbi lekhompyuter.Ixabiso lamava okuhambelana nokusetyenziswa kwamandla kwezixhobo kwigumbi lekhompyutha yeyona nto ibaluleke kakhulu.Ke ngoko, amava omenzi luphawu olubalulekileyo lokuvavanya ukuzinza kunye nobugcisa bemveliso yePDU.Isikhokelo sokuthengisa kwangaphambili: Nokuba kukho isikhokelo sokuthengisa kwangaphambili luphawu olubalulekileyo lokuba ngaba umenzi wePDU uyingcali okanye hayi.Ukuba awunayo isikhokelo sobuchule xa ukhetha kwaye ulungelelanisa, uya kuhlawula iindleko ezibuhlungu kwixesha elizayo: izixhobo azikwazi ukusebenzisa umbane, ukulinganisa amandla akonelanga, indawo esezantsi imbi, kwaye nezixhobo ezitshisiweyo kunye nokuphazamiseka kwentambo yombane kuya kulandela. isuti.
