Ukubala isikhathi sokugijima kuyisinyathelo esibalulekile ekukhetheni amandla okuphazamiseka okuphazamiseka
Ukukhetha i-UPS (Ukuphazamiseka Kwamandla Okungaphazamiseki) noma ukusekela kwebhethri kwikhompyutha yakho akufanele kube umsebenzi oyinkimbinkimbi. Kodwa kubonakala sengathi imisebenzi elula ayidabuli kalula, futhi ukukhetha i- UPS ephelele ukufanisa i-Mac yakho noma i- PC kungaba nzima kunokuba ungalindela. Sizokusiza ukuhlunga izinto.
I-UPS iyisici esibalulekile sekhompyutha ephephile. Njengama- backups avikela ulwazi olugcinwe kwikhompyutha yakho , i-UPS ivikela i-hardware yekhompyutha kusuka kumicimbi, njengokungena kwamandla kanye nokuqhubekela phambili, okungabangela umonakalo. I-UPS ingavumela futhi ikhompyutha yakho ukuba iqhubeke isebenza, ngisho nalapho amandla ephuma.
Kulo mhlahlandlela, sizobheka indlela yokukhetha u- UPS usayizi ofanele we-Mac yakho noma i-PC yakho , noma ngenxa yalolu daba, noma yiziphi izingxenye zobuchwepheshe ofuna ukuzivikela ngesistimu yokulondoloza ibhethri.
Ngaphambi kokuba siqhubeke, igama mayelana nokuthi yiluphi uhlobo lamadivayisi okufanele ucabange ngawo ukuze ulusebenzise nge-UPS. Ngokuvamile, amadivayisi we-UPS esiwakhulumayo aklanyelwe amadivaysi e-electronic anezimoto ezincane ezingekho zokufundisa. Lokhu kusho ukuthi amadivaysi afana namakhompyutha , ama- stereos , ama-TV , nezinsimbi eziningi ze-elekthronikhi bonke abazokhethwa ukuxhumeka ku-UPS. Amadivaysi anama- motor amakhulu athola amadivayisi we-UPS akhethekile, nezindlela ezihlukile zokusikisela kunalokho okuchazwe kulesi sihloko. Uma ungaqiniseki ukuthi idivayisi yakho kufanele ifakwe ku-UPS, hlola nomkhiqizi we-UPS.
Yini Ongayenza Ngayo Yakho?
UPS for imishini yakho yekhompyutha inikeza izinsizakalo ezimbili eziyisisekelo. Kungenza isimo se-voltage ye-AC, sikhiphe noma okungenani ukunciphisa ama-surges nomsindo ongaphazamisa noma ukulimaza uhlelo lwakho lwekhompyutha. I-UPS nayo ikwazi ukuhlinzeka ngesistimu yakho yekhompiyutha ngamandla okwesikhashana uma isevisi kagesi ekhaya lakho noma ehhovisi iphuma.
Ukuze i-UPS iyenze umsebenzi wayo, kufanele ifaneleke kahle ukuletha amandla anele kumadivayisi owaxhumekile. Ukufakwa kwezingxenye kuhlanganisa inani elincane lamandla adingekayo ukusebenzisa amadivayisi wakho, kanye nobude besikhathi ofuna ukuba nebhethri ye-UPS inikeze amandla okusekela.
Ukuze usayizi we-UPS, udinga ukwazi inani lamandla asetshenziswa yizo zonke amadivayisi axhunyiwe, kanye nesilinganiso sesikhathi ongathanda ukuba i-UPS ikwazi ukunikeza amandla kumadivayisi uma kwenzeka ukuphuma kwamandla . Amadivaysi angaphezulu axhunyiwe, futhi uma ufisa ukubenza bakwazi ukugijima ngamandla, i-UPS iyadingeka.
I-Wattage yedivayisi
Ukumisa i-UPS ukuze isetshenziswe ngokusetha ikhompyutha yakho kungase kubesabe, ikakhulukazi uma uhlola amawebhusayithi abakhiqizi be-UPS. Abaningi banikeza amathuluzi ahlukahlukene, amatafula, namakhasi okusebenzela ukuzama ukukusiza ukuthi ukhethe iyunithi elingana kahle kwikhompyutha yakho. Nakuba kuyesabeka ukuthi bazama ukusiza ukukufanisa neyunithi elungile, bathambekele ekuqapheliseni nasekukhuliseni inqubo.
Enye yezindinganiso ezibalulekile okudingeka wazi ukuthi inani le-wattage uhlelo lwe-UPS luzodinga ukuletha. I-Wattage ingumlinganiselo noma amandla futhi ichazwa njengomuntu owodwa ngomzuzwana. Kuyinto ye-SI (Système International) yesilinganiso esingasetshenziswa ukukala amandla. Njengoba sisebenzela ngokuqinile ngamandla kagesi, singakwazi ukucubungula incazelo yamanzi ukuze kube yindlela yamandla kagesi afana nomthamo (V) wanda ngamanje (I) esifundeni (W = V x I). Isifunda esimweni sethu yiwona amadivaysi oxhuma ku-UPS: ikhompyutha yakho, umqapha, nanoma yikuphi okuphathelene nendawo.
Cishe wonke amadivaysi kagesi azoba ne-voltage, amperes, kanye / noma i-wattage efakwe kuhlu lwelebula elibekwe kubo. Ukuze uthole inani, ungamane wengeze ndawonye inani le-wattage elifakwe kuhlu lwedivayisi ngayinye. (Uma kungabikho ukudonsa okuhlongozwayo, phindaphinda i-voltage x i-amperage.) Lokhu kuzokhipha inani okufanele libe yi-wattage esiphezulu wonke amadivayisi angase akhiqize. Inkinga ngokusebenzisa le nombolo ukuthi ayikhombisi ukuthambisa okwenziwe njalo ngesistimu yakho yekhompyutha; esikhundleni salokho, kuyinani eliphakeme kunazo zonke ongase ubone, njengokuthi konke kuqale kuqala, noma uma ikhompiyutha yakho ixhunywe nazo zonke izengezo ezitholakalayo futhi yenza imisebenzi eyinkimbinkimbi edinga amandla amaningi.
Uma ufinyelela ku-wattmeter ephathekayo, njenge-popular Ukubulala i-Watt imitha, ungangena kuphela ikhompyutha yakho kanye nemiphakheji futhi ulinganise ngokuqondile umthamo osetshenziswayo.
Ungasebenzisa noma inani eliphakeme kakhulu le-wattage noma inani lokulinganisela kwamanzi owaqoqa usebenzisa i-Wattmeter. Ngamunye unenzuzo. Inani eliphakeme kakhulu le-wattage lizoqinisekisa ukuthi i-UPS ekhethiwe izokwazi ukukhipha ikhompiyutha yakho nemiphaketheni ngaphandle kokukhathazeka, futhi njengoba ikhompiyutha yakho ingenakwenzeka ukuba isebenze ngamandla amakhulu uma i-UPS iyadingeka, amandla angasetshenzisiwe angeke abe esetshenziswe yi-UPS ukuze uvumele ikhompyutha yakho isebenze isikhathi esingaphansi kwebhethri.
Ukusebenzisa inani lokulinganisela kwamanzi kukuvumela ukuba ukhethe i-UPS esekelwe ngokunembile kakhulu ngezidingo zakho, okusiza ukugcina izindleko ezincane kakhulu kunalokho uma usebenzisa isamba esiphezulu se-wattage.
VA Isilinganiso
Manje ukuthi uyazi ukulinganiswa kwamanzi wekhompiyutha yakho namakhemikhali, ungase ucabange ukuthi ungaqhubeka futhi ukhethe u-UPS. Uma usuvele ubheka amadivaysi e-UPS, cishe uye waphawula ukuthi abakhiqizi be-UPS abasebenzisi i-wattage (okungenani hhayi ngokuqondile) ekucabangeni iminikelo yabo ye-UPS. Kunalokho, basebenzisa i-VA (Volt-Ampere) isilinganiso.
Isilinganiso se-VA sisilinganiso samandla avela ku-AC (Alternating Current) wesifunda. Njengoba ikhompiyutha yakho kanye nemiphriphthi yakho isebenzisa i-AC ukuyiqhuba, isilinganiselwa se-VA yindlela efanele kakhulu yokukala amandla angempela adliwe.
Siyabonga ukuthi singasebenzisa ukulingana okulula okuzobuyisela umthetho ophelele wokuguqulwa kwesithupha kusuka ku-wattage kuya ku-VA:
VA = ukushisa x 1.6Isibonelo, uma uhlelo lwakho lwekhompiyutha kanye nemiphakheji inamanzi amaningi angu-800, khona-ke izinga elincane le-VA ozolihlola ku-UPS lingaba ngu-1,280 (800 watts olwandiswa yi-1.6). Uzozungeza lokhu kuze kube esilinganisweni esilandelayo se-UPS VA esitholakalayo, cishe cishe i-1,500 VA.
Isilinganiso esincane se-VA sisho kuphela ukuthi i-UPS iyakwazi ukunikeza amandla adingekayo ohlelweni lwakho lwekhompyutha; ayibonisi isikhathi sokuqalisa , noma i-UPS izokwazi kangakanani ukufaka amandla uhlelo lwakho ngokuhluleka kwamandla.
Isikhathi se-UPS
Kuze kube manje, usuqaphele ukuthi amandla angakanani ekutheni usebenzise uhlelo lwakho lwekhompyutha. Ubuye uguqule isilinganiselo se-wattage ukuze uthole isilinganiso esincane se-VA esidingekayo ku-UPS ukuze usebenzise uhlelo lwakho lwekhompyutha. Manje sekuyisikhathi sokuthola inani le-runtime ye-UPS oyodinga.
Uma sikhuluma nge-runtime yokugijima kwe-UPS, sikhathazeke ngokuthi i-UPS iyothatha isikhathi esingakanani amandla okusebenzisa uhlelo lwakho lwekhompiyutha ezingeni elilindelekile lokuphuza amanzi ngesikhathi sokuphuma kwamandla.
Ukubala isikhathi sokugijima, udinga ukwazi ukulinganisa okungenani okungenani kwe-VA, umthamo webhethri, ukulinganisa kwe-alamu kwamabhethri, nokusebenza kwe-UPS.
Ngeshwa, amanani adingekayo akatholakali atholakale kumkhiqizi, nakuba ngezinye izikhathi avele ngaphakathi kwe-manual ye-UPS noma imininingwane yezobuchwepheshe.
Uma ungakwazi ukuthola izimiso, ifomula yokuthola isikhathi sokugijima yilesi:
Runtima emahoreni = (Amanani webhethri x Amaphora x Ukuphumelela) / isilinganiso esincane se-VA.Inani elibaluleke kunazo zonke ukuzitholela ukufaneleka. Uma ungeke ukwazi ukuthola leli nani, ungafaka esikhundleni .9 (amaphesenti angu-90) njengenani elifanele (futhi elincane) elisebenzayo le-UPS yesimanje.
Uma ungatholi yonke imingcele edingekayo ukwenza ukubalwa kwesikhathi sokuqalisa, ungazama ukuvakashela isayithi lomkhiqizi we-UPS futhi ufune igrafu yokugijima / umthwalo we-UPS ovumela ukuthi ufake ama-wattage noma i-VA amanani wokulinganisa owaqoqa.
Umkhethi we-APC UPS Load
I-CyberPower Runtime Calculator
Ukusebenzisa i-equation ye-runtime engaphezulu, noma umbala wokubala wokukhiqiza, ungabona ukuthi isikhathi sokuqalisa umodeli othile we-UPS uzokwazi ukuhlinzeka ngesistimu yakho yekhompyutha.
Isibonelo, i- CyberPower CP1500AVRLCD , engiyisebenzisela i-Mac yami nemiphakheji, isebenzisa ibhetri engu-12-volt elilinganiselwe kumahora angu-9 Amp ne-90% esebenzayo. Ingahlinzeka ngamandla okusekelayo amaminithi angu-4.5 ohlelweni lwekhompyutha elidweba i-1,280 VA.
Lokhu kungase kungabonakali njengokuningi, kepha imizuzu engu-4.5 ilinde ngokwanele ukuthi ulondoloze noma iyiphi idatha futhi wenze ukuvala okumnandi. Uma ufuna isikhathi esiphezulu, kuzodingeka ukhethe i-UPS ngokusebenza kangcono, ibhethri ehlala isikhathi eside, amabhethri aphezulu aphezulu, noma konke okungenhla. Eqinisweni, ukukhetha i-UPS ngesilinganiso esiphakeme se-VA ngaphakathi futhi ngokwayo akukwenzi lutho ukwandisa isikhathi sokugijima, nakuba abakhiqizi abaningi be-UPS bazofaka amabhethri amakhulu ezinkampanini ze-UPS ngokulinganisa okukhulu kwe-VA.
Izici ze-UPS ezengeziwe okufanele uzicabangele
Kuze kube manje, sibheke ukuthi singasayizi kanjani i-UPS hhayi kunoma yiziphi ezinye izici ze-UPS okufanele zicatshangelwe.
Ungathola kabanzi mayelana nezisekelo ze-UPS kanye nezici abesekela kulo mhlahlandlela: Iyini Ibhethri Backup?
Into eyodwa okumele uyihlole lapho ukhetha i-UPS ibhethri. I-UPS iyitshalomali ekulondolozeni uhlelo lwakho lwekhompyutha. I-UPS inenxenye eyodwa engaguqulwayo: ibhethri elizodinga ukushintshwa ngezikhathi ezithile. Ngokwesilinganiso, ibhetri ye-UPS idlala iminyaka engu-3 kuya kwezingu-5 ngaphambi kokuthi idluliselwe esikhundleni.
Amadivayisi we-UPS ngokuvamile enza izivivinyo ngezikhathi zebhethri ukuqinisekisa ukuthi usazokwazi ukuhlinzeka ngamanzi athile uma kudingeka. Amadivayisi amaningi we-UPS azokunikeza isixwayiso uma ibhethri idinga ukushintshwa, kodwa abambalwa bayomane bayeke ukusebenza ngesikhathi esizayo ababizwa ukuba banikele amandla okusekelayo.
Qinisekisa ukuthi uhlola ibhuku le-UPS ngaphambi kokuthenga ukuqinisekisa ukuthi uma ibhethri lihluleka, i-UPS inikeza imodi yokudlula evumela i-UPS ukuthi isebenze njengesivikelo sokuqhubekela phambili kuze kufike esikhundleni sebhethri.
Futhi ekugcineni, uma nje uhlola ibhethri, ungase ufise ukunquma izindleko zokufaka esikhundleni. Mhlawumbe uzoshintsha ibhethri izikhathi ezimbalwa phakathi nokuphila kwe-UPS, ngakho ukwazi izindleko nokuthi amabhethri ayatholakala kalula yini umqondo omuhle ngaphambi kokukhetha i-UPS.
