Ukubala i-runtime yinqanaba eliphambili ekukhethweni koMbane ongenakuphazamiseka
Ukukhetha i-UPS (Ukunikezelwa kweMandla okungaphazamisekiyo) okanye ukugcinwa kwebhethri kwikhompyutheni yakho akufanele kube yinto enzima. Kodwa kubonakala ngathi imisebenzi elula ayidla ngokulula, kwaye ukukhetha i- UPS epheleleyo ukufanisa iMac okanye iPC yakho ingaba nzima kunokuba ungalindela. Siza kukunceda uhlele izinto.
I-UPS yinto ebalulekileyo yekhompyutha ekhuselekileyo. Njengoko iifayile zikhusela ulwazi olugcinwe kwikhompyutheni yakho , i-UPS ikhusela i-hardware yekhompyutheni kwiziganeko, ezifana nokuphuma kwamandla kunye nokunyuka, okungabangela umonakalo. I-UPS ingavumela ikhompyutha yakho ukuba iqhubeke nokusebenza, nangona xa amandla aphuma.
Kule khokelo, siza kujonga indlela yokukhetha udidi lwe- UPS lwe-Mac okanye i-PC yakho , okanye malunga naloo nto, naziphi na izixhobo zecomputer ofuna ukuzikhusela kwinkqubo yokulondoloza ibhetri.
Ngaphambi kokuba siqhubeke, igama malunga naluphi uhlobo lwezixhobo onokuzicingela ukuze ulisebenzise nge-UPS. Ngokuqhelekileyo, iifayile ze-UPS esizithethayo zenzelwe amacebo e-elektroniki kunye neenjini ezincinci ezingabonakaliyo. Oku kuthetha iifowuni ezifana neikhomputha , ii- stereos , iiTV , kunye neendlela ezininzi ze-electronics bonke abaviwa ukuba baxhunywe kwi-UPS. Amadivaysi aneenjini ezinkulu ezinokukhupha zidinga iiplani ze-UPS ezikhethekileyo, kunye neendlela ezahlukeneyo zokucwangcisa kunokuba zichazwe kweli nqaku. Ukuba awuqinisekanga ukuba ifowuni yakho kufuneka ifakwe kwi-UPS, tshekisha umenzi we-UPS.
Yintoni ongayenza i-UPS kuwe?
I-UPS yezixhobo zakho zekhomputha zibonelela ngeenkonzo ezimbini eziphambili. Iyakwazi ukumelana nombane we-AC, ukuphelisa okanye ubuncinci ukunciphisa amaninzi kunye nengxolo engaphazamisa okanye eyonakalisa inkqubo yakho yekhompyutha. I-UPS nayo inakho ukubonelela ngekhompyutheni yakho ngegunya lesigxina xa isevisi yombane ekhayeni lakho okanye kwiofisi iphuma.
Ukuze i-UPS iyenze umsebenzi wayo, kufuneka ukuba ubukhulu bungakanani ukuze unike amandla okwaneleyo kwizixhobo ozixhunyiwe. Ukukhangela kubandakanya ubuncinane bemandla efunekayo ukuqhuba izixhobo zakho, kunye nobude bexesha ofuna ukuba nebhethri ye-UPS inike amandla okugcina.
Ukuze ukhulule i-UPS, kufuneka ukwazi inani lemandla elisetyenziswe kuzo zonke izixhobo ezixhunyiwe, kunye nesixa sithuba othanda ukuba i-UPS ikwazi ukunika amandla kumadivayisi xa kwenzeka umbane . Ezinye iinkcukacha zixhunyiwe, kwaye xa unqwenela ukuba nazo zikwazi ukuqhuba ukuphuma kwamandla, i-UPS ekhudlwana oyifunayo.
Ukusetyenziswa kwamanzi
Ukukhangela i-UPS ukuze usebenzise ngokucwangciswa kwekhompyutheni yakho kunokusongela, ingakumbi ukuba ukhangele iiwebhusayithi ze-UPS. Abaninzi banikeza izixhobo ezahlukeneyo, amatafula, kunye namaphepha okusebenzela ukuzama ukukunceda ukhethe iteksi elungileyo ngokufanelekileyo kwikhompyutha yakho. Nangona kukhwankqisayo ukuba bazama ukukuncedisa ukulinganisa nawe kwiyunithi elungileyo, bathambekele ekugqibeleni kwaye banciphise inkqubo.
Enye yexabiso elibalulekileyo omele ukwazi ukuba liyi-system ye-UPS iya kufuneka idibanise. Ukuthambisa ngumlinganiselo okanye amandla kwaye uchazwa njengomnye umdlalo ngesibini. I-SI (iSystem International) iyunithi yesilinganiselo engasetyenziswa ukulinganisa amandla. Ekubeni sisebenza ngokuqinileyo ngamandla kagesi, sinokuyicokisa intsingiselo yokuluthwa kwamanzi ukuba ibe ngumlinganiselo wamandla kagesi alinganayo nombane (V) wanda ngoku (I) kwisiphaluka (W = V x I). Isiphaluka kwimeko yethu zixhobo ozixhuma kwi-UPS: ikhomputha yakho, i-monitor, kunye nayiphina imitha.
Phantse zonke iifowuni zombane ziza kuba ne-voltage, amperes, kunye / okanye i-wattage ezidweliswe kwiilebula ezifakwe kubo. Ukufumana isixa-mali, unokongeza nje uxabiso lwamanzi ekudweliswe kwisixhobo ngasinye. (Ukuba akukho luchule lucwecwe, yandisa i-voltage x i-amperage.) Oku kuza kuvelisa ixabiso elifanele libe lilamandla amaninzi onke amacebo anokuvelisa. Ingxaki ngokusebenzisa le nombolo kukuba ayibonakali ukutshiza okuqhelekileyo okusetyenziswa rhoqo ngekhompyutha yakho; Kunoko, yinto ephezulu kakhulu enokuyibona, njengokuba yonke into iqala ukuqala, okanye ukuba unakho ikhompyuter yakho kunye nazo zonke izongezelelo ezikhoyo kunye nokwenza imisebenzi eyinkimbinkimbi efuna inani elininzi lamandla.
Ukuba unako ukufikelela kwi-wattmeter ephathekayo, njengokwindawo eyaziwayo yokubulala i-Watt meter, ungazicoca nje kwikhompyutheni yakho kunye nemida kunye nokulinganisa ngokuchanekileyo ukusetyenziswa kwamanzi.
Ungasebenzisa nokuba lixabiso eliphezulu lokutshiza okanye ixabiso lokulinganisela umbane owaqoqa usebenzisa i-wattmeter. Ngamnye unamathuba ayo. Ixabiso eliphezulu lamathamo liya kuqinisekisa ukuba i-UPS ekhethiweyo iya kukwazi ukulawula ikhompyutha yakho kunye nemipheripha ngaphandle kwenkxalabo, kwaye ekubeni ikhompyutha yakho ingenakusebenza ngokusemandleni ekuphakamileyo xa i-UPS iyadingeka, amandla angasetyenziswanga esetyenziswe yi-UPS ukuvumela ikhompyutha yakho isebenze ixesha elide kwibhetri.
Ukusebenzisa ixabiso lokulinganisela umthamo kukuvumela ukuba ukhethe i-UPS enokuchaneka ngokuchanekileyo kwiimfuno zakho, ekuncedeni ukugcina iindleko ezincinci kunokuba usebenzise ixabiso elincinci lomthamo.
VA Rating
Ngoku ukuba uyazi ukulinganiswa kwamanzi kwikhompyutheni yakho kunye nemipheripheral, ungacinga ukuba ungaya phambili kwaye ukhethe i-UPS. Ukuba sele ukhangele kwii-UPS izixhobo, mhlawumbi uqaphele ukuba abavelisi be-UPS abasebenzisi ukusebenzisa umthamo (ubuncinane ngokukodwa) ngokucwangcisa i-UPS iminikelo yabo. Kunoko, basebenzisa ii-VA (Volt-Ampere).
Isilinganiselo se-VA sisilinganiselo samandla avela kwi-AC (i-Alternate Current). Ekubeni ikhompyutheni yakho kunye neeripheriti zisebenzisa ii-AC ukuba zigijime, i-VA yokulinganisa yindlela efanelekileyo yokulinganisa amandla okwenziweyo.
Siyabonga, sinokusebenzisa ukulingana okulula okuza kubuya umyalelo ofanelekileyo wokuguqulwa kwesithuthuthu ukusuka kumanzi ukuya ku-VA:
VA = utywala x 1.6Ngokomzekelo, ukuba inkqubo yakho yeekhomputha kunye neeripheriti zazinamanzi angama-800, ngoko ubuncinane ubuncinane be-VA ubungakanani obuya kukhangela kwi-UPS buza kuba yi-1,280 (800 watts yanda nge-1.6). Uya kujikeleza oku ukuya kwi-standard standard ye-UPS VA efumanekayo, ininzi i-1,500 VA.
Ubuncinane be-VA kuphela bubonisa ukuba i-UPS inako ukubonelela amandla afunekayo kwikhompyutha yakho; ayibonakali ixesha lokuqalisa , okanye ixesha elide i-UPS iya kuba nakho ukunika amandla inkqubo yakho kwintsholongwane yamandla.
Inkqubo ye-UPS
Kuze kube ngoku, ufumanise ukuba ungakanani amandla ekutyeni inkqubo yakho yekhompyutha. Ubuye uguqulwe umlinganiselo wokutywala ukuze ufumane ubuncinane be-VA yokulinganisa efunekayo kwi-UPS ukuqhuba inkqubo yakho yekhompyutha. Ngoku sekuyisikhathi sokuqonda inani lexesha lokugqibela le-UPS oza kuyimfuneko.
Xa sithetha ngexesha lokugijima kwe-UPS, sikhathazeke malunga nexesha elide le-UPS luza kukwazi ukwenza amandla kwikhompyutha yakho kwinqanaba elilindelekileyo lokutywala ngexesha lokuphuma kwamandla.
Ukubala ixesha lokuqalisa, kufuneka ukwazi ubuncinane be-VA, ibhetri yombane, ukulinganiswa kweeyure zamabhetri kunye nokusebenza kwe-UPS.
Ngelishwa, iinqununu ezifunekayo azifumaneki zivela kumvelisi, nangona ziza kuvela ngezinye iikhompyutheni ze-UPS okanye iinkcukacha zobugcisa.
Ukuba unako ukuqinisekisa ubungakanani, i-formula yokufumana ixesha lokusebenza yilo:
I-Runtime ngeeyure = (I-Battery voltage x Amp hora x Ukusebenza) / ubuncinane be-VA.Ixabiso elona lukhuni ngakumbi ukuyifumanisa ngempumelelo. Ukuba awukwazi ukufumana le xabiso, ungathatha indawo .9 (iipesenti ezingama-90) njengenani elifanelekileyo (kunye nelona elondolozayo) kwi-UPS yesimanje.
Ukuba awukwazi ukufumana zonke iipameters ezifunekayo ukwenza ukubala kwexesha lokusebenza, unokuzama ukutyelela isayithi lomenzi we-UPS kwaye ukhangele i-runtime / umthwalo we-UPS okanye ukhetha umkhethi we-UPS ovumela ukuba ufake ukungena kwamanzi okanye ii-VA zokulinganisela.
Ikhefu le-APC UPS Umthwalo
CyberPower Runtime Calculator
Ukusebenzisa i-equator equator equation, okanye i-calculator ye-runtime calculator, unokuqinisekisa ukuba ixesha lokuqalisa umzekelo othile we-UPS uza kukwazi ukubonelela ngekhompyutheni yakho.
Ngokomzekelo, i- CyberPower CP1500AVRLCD , endiyisebenzisela iMac kunye nemipheripheral yam, isebenzisa ibhetri ye-12-volt ebalwe kwii-9 ze-Amp ngeeyure ezingama-90. Inokunika amandla okugcina amandla ama-4.5 imizuzu kwinkqubo yekhomputha yokudweba i-1,280 VA.
Oku kungabonakali ngathi kuninzi, kodwa imizuzu engama-4.5 ubude ngokwaneleyo ukuba ulondoloze nayiphi na idatha kwaye wenze ukuvalwa kokumnandi. Ukuba ufuna ixesha elide, kufuneka ukhethe i-UPS ngokusebenza kakuhle, ibhetri engapheliyo, ibhetri ephezulu yamandla okanye konke oku ngasentla. Enyanisweni, ukukhetha i-UPS kunye ne-VA ephezulu kwaye ngokwayo ayinanto yokwandisa ixesha lokusebenza, nangona abaninzi abavelisi be-UPS ba ndakanya amabhetri amakhulu kwiimodeli ze-UPS kunye nokulinganisa okukhulu kwe-VA.
Iimpawu ze-UPS ezongezelelweyo Ukuqwalasela
Kuze kube ngoku, sijonge indlela yokwenza i-UPS kwaye ingabi naziphi na ezinye iimpawu ze-UPS okufanele ziqwalaselwe.
Unokufumana okungakumbi malunga neenjongo ze-UPS kunye neempawu ezixhasayo kwisikhokelo: Yintoni iBaltery Backup?
Enye into ekufuneka uyiqwalasele xa ukhetha i-UPS ibhetri. I-UPS yintalo-mali ekukhuseleni inkqubo yakho yekhompyutha. I-UPS inomlinganiselo omnye ongaguqulwayo: ibhetri eyo kufuna ukutshintshwa kwixesha elide. Ngokomyinge, ibhetri ye-UPS ihlala iminyaka emi-3 ukuya kwe-5 ngaphambi kokuba ithathe indawo.
Iifayile ze-UPS ziqhuba iimvavanyo zexesha elide zebhethri ukuqinisekisa ukuba zisakwazi ukubonelela umbane xa zibizwa. Izixhobo ezininzi ze-UPS ziza kunika isilumkiso xa ibhetri idinga ukutshintshwa, kodwa bambalwa baya kuyeka ukusebenza ngexesha elizayo xa babizwa ukuba banikele amandla okugcina.
Qinisekisa ukujonga incwadana ye-UPS ngaphambi kokuba uthenge ukuqinisekisa ukuba xa ibhetri ihluleka, i-UPS inikeza indlela yokupasa evumela ukuba i-UPS iqhubeke isebenza njengomkhuseli okhulayo kuze kube yilapho ibhetri ishintshwa.
Kwaye ekugqibeleni, ngokungakhathaliseki ukuba uhlola ibhetri, unokuba unqwenela ukufumanisa indleko yokubuyisela. Mhlawumbi uzakutshintsha ibhetri ngamaxesha ambalwa ngexesha lobomi be-UPS, ngoko ukwazi iindleko nokuba ingaba iibhetri ziyafumaneka ngokukhawuleza ingcamango enhle ngaphambi kokukhetha i-UPS.
