Yog tias koj nkag tau mus rau ib lub khoom xa xov hneev taw, xws li nrov tua Tua Ib Tug Wat, koj tuaj yeem ntsaws rau hauv koj lub computer thiab peripherals thiab ncaj qha ntsuas cov wattage siv.
Koj tuaj yeem siv tus nqi siab tshaj plaws lossis tus nqi nruab nrab ntawm qhov koj tau sau siv lub wattmeter. Txhua tus muaj nws qhov zoo. Tus nqi siab tshaj plaws yuav ua kom ntseeg tau tias UPS xaiv tau lub hwj chim koj lub computer thiab cov peripherals tsis muaj kev txhawj xeeb, thiab vim tias koj lub computer tsis tshua tau khiav ntawm lub hwj chim siab thaum lub caij tsim nyog, lub hwj huam tsis siv ntxiv yuav yog siv los ntawm UPS kom koj lub computer khiav me ntsis ntev dua lub roj teeb.
Siv qhov nruab nrab nqi wattage tso cai rau koj xaiv ib lub UPS uas muaj ntau qhov tseeb rau koj cov kev xav tau, pab ua kom qis me ntsis qis tshaj yog tias koj siv cov nqi siab tshaj plaws.
VA Kev Ntsuam Xyuas
Tam sim no koj paub qhov kev ntsuam xyuas ntawm koj lub computer thiab cov peripherals, koj yuav xav tias koj yuav mus tom ntej thiab xaiv ib qho UPS. Yog tias koj twb tau saib UPS lawm, koj twb pom tias UPS cov kws kho mob tsis siv cov wattage (tsawg kawg tsis ncaj qha) hauv kev siv lawv cov UPS. Xwb, lawv siv lub VA (Volt-Ampere) ntsuam xyuas.
Kev ntsuam xyuas VA yog ib qho kev ntsuas ntawm qhov pom muaj zog hauv AC (Lwm Yam Tam Sim No) Circuit Court. Vim tias koj lub computer thiab cov peripherals siv AC khiav rau lawv, VA qhov kev ntsuam xyuas yog qhov tsim nyog tshaj plaws los ntsuas qhov kev siv hluav taws xob lub zog.
Ua tsaug, peb tuaj yeem siv qhov sib npaug yooj yim uas yuav rov qab tau txoj cai zoo ntawm tus ntiv tes xoo ntawm kev hloov mus rau VA:
VA = wattage x 1.6Ua ib qho piv txwv, yog tias koj lub tshuab computer nrog rau cov neeg ua haujlwm hauv qhov nruab nrab tau muaj tag nrho ntawm 800, ces qhov ntsuas VA kawg koj yuav tsum nrhiav hauv ib ce yuav tsum 1,280 (800 watts multiplied by 1.6). Koj yuav muab qhov no nce mus rau tus txheej txheem tom ntej UPS VA muaj, feem ntau yuav yog 1,500 VA.
Yam tsawg kawg nkaus VA ntsuam xyuas tsuas yog qhia tias UPS muaj peev xwm muab lub hwj chim tsim nyog rau koj lub computer system; nws tsis qhia lub sij hawm ua haujlwm , los yog ntev npaum li cas cov UPS yuav muaj peev xwm tswj koj lub zog hauv kev ua haujlwm tsis muaj zog.
UPS Runtime
Li ntawd, nyob deb, koj twb paub tias ntau npaum li cas nyob rau hauv koj lub zog siv koj lub computer siv. Koj kuj tau hloov qhov ntsuas qhov ntsuas kom pom qhov tsawg kawg nkaus VA qho tsim nyog rau UPS los khiav koj lub computer system. Tam sim no nws yog lub sij hawm los pom qhov nqi ntawm UPS runtime koj yuav tsum tau.
Thaum peb hais txog UPS runtime, peb txhawj xeeb txog tias ntev npaum li cas hauv chav tsev UPS yuav muaj peev xwm siv koj lub tshuab computer los ntawm qhov kev xav tau wattage thaum lub sijhawm fais fab tuag.
Xav suav runtime, koj yuav tsum paub qhov VA rating yam tsawg, roj teeb voltage, kev ntsuam xyuas amp-hour ntawm lub roj teeb, thiab qhov ua tiav ntawm qhov UPS.
Hmoov tsis, qhov tseem ceeb yuav tsum tau muaj los ntawm lub khw, tab sis lawv yuav qee zaum hauv UPS phau ntawv los yog cov lus qhia.
Yog tias koj tuaj yeem paub txog qhov tseem ceeb, tus qauv ntawm kev nrhiav qhov runtime yog:
Runtime hauv xuab moos = (Teeb meem roj teeb x Amp teev x Qhov ua tau zoo) / qhov ntsuas VA kawg.Tus nqi zog tshaj plaws rau kev paub yog qhov ua tau zoo. Yog tias koj nrhiav tsis tau qhov txiaj ntsim no, koj tuaj yeem hloov .9 (90 feem pua) raws li qhov tsim nyog (thiab me ntsis kev txhawj xeeb) rau ib qho UPS niaj hnub no.
Yog tias koj tsis tuaj yeem pom tag nrho cov tsis xav tau ua qhov kev suav runtime, koj tuaj yeem mus saib xyuas cov UPS cov chaw ua haujlwm thiab nrhiav ib runtime / load graph lossis UPS selector uas tso cai rau koj nkag mus rau cov nqi ntawm cov nqi lossis cov nqi VA.

CyberPower Runtime Calculator
Siv ob tog sib npaug runtime saum toj saud, lossis lub chaw ua haujlwm runtime calculator, koj tuaj yeem paub lub sijhawm runtime ib hom qauv UPS yuav muab tau nrog koj lub computer system.
Ua ib qho piv txwv, ib qho CyberPower CP1500AVRLCD , uas kuv siv rau kuv Mac thiab peripherals, siv 12-volt roj teeb nyob rau ntawm 9 Amp cov sij hawm nrog 90 feem pua ntawm kev ua haujlwm. Nws tuaj yeem muab lub hwj huam txhawb zog rau 4.5 feeb rau lub computer system teeb duab 1,280 VA.
Qhov ntawd yuav tsis zoo li ntau, tab sis 4.5 feeb yog ntev txaus rau koj kom txuag tau tej ntaub ntawv thiab ua kom muaj kev sib txig sib luag. Yog tias koj xav tau ntev runtime, koj yuav tau xaiv ib lub UPS nrog kev ua haujlwm zoo dua, roj teeb ntev dua, roj teeb siab dua, lossis tag nrho cov saum toj no. Yeej, xaiv ib lub UPS nrog VA ntsuam xyuas dua thiab nws tus kheej tsis muaj dab tsi los nce runtime, tab sis feem ntau cov khw UPS yuav nrog cov roj teeb loj hauv UPS cov qauv uas muaj txiaj ntsig loj VA.
Ntxiv UPS Cov Nta Txawj Xav Txog
Li ntawd, nyob deb, peb twb ntsia seb yuav ua li cas ib tug UPS thiab tsis nyob rau ntawm lwm cov nta ntawm ib lub UPS uas yuav tsum tau xav txog.
Koj tuaj yeem paub ntxiv txog UPS qhov tseem ceeb thiab cov txheej xwm uas lawv txhawb nqa nyob hauv phau ntawv qhia: Cov roj Backup yog dab tsi?
Ib qho ntxiv rau xav txog thaum xaiv UPS yog lub roj teeb. Ib lub UPS yog ib qho peev hauv kev tiv thaiv koj lub computer system. Lub UPS muaj ib qho khoom pauv: lub roj teeb uas yuav tsum tau hloov los ntawm lub sijhawm dhau ib zaug. Qhov nruab nrab, lub roj teeb UPS kav ntev li 3 txog 5 xyoos ua ntej nws yuav tsum tau hloov.
Feem ntau UPS cov cuab yeej ua rau lub caij kuaj roj ntsha los xyuas kom meej tias nws tseem muaj peev xwm muab cov khoom tsim nyog uas yuav tsum tau muaj thaum wb hu. Muaj ntau lub UPS cov khoom siv yuav ceeb toom rau koj thaum lub roj teeb yuav tsum tau hloov, tab sis ob peb yuav tsis ua hauj lwm rau lwm zaus uas lawv raug hu los muab kev siv hluav taws xob.
Nco ntsoov xyuas cov phau ntawv qhia txog UPS ua ntej yuav khoom los mus tshawb xyuas tias thaum lub roj teeb tsis ua haujlwm, UPS muab hom sib tw dhau los uas cia UPS tseem ua haujlwm raws li kev tiv thaiv kom mus txog thaum hloov roj.
Thiab thaum kawg, ntev li ntev tau thaum koj saib xyuas ntawm lub roj teeb, koj tuaj yeem txiav txim siab txog tus nqi them rov qab. Koj yuav muaj peev xwm hloov lub roj teeb ob peb zaug hauv lub neej ntawm UPS, yog li paub txog cov nqi thiab seb cov roj teeb puas muaj txhij txhua yog ib lub tswv yim zoo ua ntej xaiv ib lub UPS.
