Txhawm rau loj koj xav tau: Tag nrho watts ntawm koj cov cuab yeej x lawv cov amperage tag nrho thiab ntxiv 15% ntawm tag nrho cov ntawd kom tau txais koj cov kev xav tau tag nrho.
- Qhov txawv ntawm UPS muaj peev xwm piv rau nws cov load tuaj yeem ua rau lub sijhawm ua haujlwm yog tias tseem ceeb txaus.
Kab lus no piav qhia yuav ua li cas los txiav txim siab txoj cai tsis muaj kev cuam tshuam fais fab loj kom haum rau koj cov kev xav tau.
Yuav Loj npaum li cas Kuv Lub Hwj Chim Tsis Muaj Kev cuam tshuam yuav yog?
Peb yam tseem ceeb uas yuav tsum tau xav txog thaum teeb tsa UPS yog qhov xav tau thauj khoom (piv txwv li, qhov sib xyaw ua ke thiab qhov amperage ntawm txhua yam khoom siv hluav taws xob sib txuas), lub peev xwm (i.e., lub zog tso zis siab tshaj plaws), thiab lub sijhawm ua haujlwm (piv txwv li, nws tuaj yeem muab roj teeb lub zog ntev npaum li cas). UPS yog qhov ua tau zoo tshaj plaws thaum lub peev xwm ua tau zoo sib xws rau tag nrho cov load yam tsis poob qis dua qhov tsim nyog. Hauv lwm lo lus, koj yuav xav kom tsis txhob siv UPS nrog lub peev xwm qis dua li qhov xav tau.
Lub sijhawm tsim nyog rau koj lub UPS nyob ntawm seb koj xav tau lossis xav tau koj cov khoom siv txuas txuas ntxiv mus ua haujlwm thaum lub sijhawm hluav taws xob. Cov roj teeb loj dua lossis cov roj teeb sab nraud (yog tias UPS txhawb nqa lawv) yuav ua rau lub sijhawm ua haujlwm. Ntawm qhov tod tes, ntau cov khoom siv thiab ntau lub zog kos txo qis runtime.
- Xaiv tag nrho cov khoom siv hluav taws xob uas koj yuav txuas rau UPS.
- Txiav txim siab qhov voltage thiab amperage rau txhua lub cuab yeej. Nws yuav tsum muab tso rau hauv lub cuab yeej cov ntaub ntawv los yog teev rau ntawm nws lub npe.
- Mua qhov voltage los ntawm amperage los xam txhua lub cuab yeej volt-amp (VA) ntsuas, tom qab ntawd ntxiv tag nrho cov kev ntsuas VA ua ke los txiav txim siab tag nrho VA tsim nyog rau koj lub UPS.
- Nws raug pom zoo kom tshaj koj cov VA tag nrho los ntawm 10% mus rau 15% (lossis ntau dua) los muab kev tiv thaiv me ntsis thiab tus lej rau kev loj hlob dhau sijhawm.
- Rau suav txog qhov kev loj hlob tsis zoo / yav tom ntej, muab koj cov VA tag nrho los ntawm 1.15 rau 15%, 1.20 rau 20%, thiab lwm yam.
- Sib piv koj VA tag nrho (zoo dua nrog tsawg kawg 15% mus rau 20% kev hloov kho) rau UPS cov zis / VA ntsuas kom pom ib qho uas haum zoo.
Piv txwv li, yog tias koj npaj yuav sib txuas ib qho M1 Mac mini (2020), uas siv qhov siab tshaj plaws ntawm 39 watts thiab ib ncig ntawm tsib amps yog tias nws siv txhua hnub, qhov ntsuas VA yuav yog 195 (39 x 5).). VA tag nrho yuav dhau los ua 224.25 (195 x 1.15), suav txog 15% kev loj hlob.
Kuv Paub Kuv Lub Peev Xwm UPS Li Cas?
Lub peev xwm ntawm koj lub UPS yog nws qhov tso zis ntau tshaj plaws (AKA VA ntsuas). Thaum yuav khoom rau UPS, VA ntsuas yuav tsum tau teev nrog rau hom (Standby, Line-Interactive, lossis On-Line), input voltage, thiab lwm yam, ntawm lub thawv lossis nplooj ntawv khoom. Yog tias koj twb muaj UPS thiab xav kuaj, lub peev xwm yuav tsum nyob rau hauv cov ntaub ntawv uas tuaj nrog UPS thiab tso tawm qhov chaw ntawm UPS casing nws tus kheej (tej zaum ntawm ib sab, nraub qaum, lossis hauv qab).
kab hauv qab
Lub sijhawm muaj peev xwm rau 300 watt UPS feem ntau nyob ntawm kev tsim thiab qauv nws tus kheej thiab ze li cas rau lub peev xwm ntawm kev sib txuas. Qee qhov UPS yuav nyob ib ncig ntawm peb feeb nrog kev thauj khoom tag nrho, qee qhov mus txog tsib feeb, thiab lwm yam. Yog tias UPS ua haujlwm ntawm qhov tsawg dua qhov load tag nrho, nws yuav muaj peev xwm muab lub zog thaub qab rau ntev dua li qhov nws xav tau. Qee qhov UPS kuj tseem sau lawv lub sijhawm ua haujlwm tag nrho, txawm tias koj tuaj yeem suav rau koj tus kheej yog tias tsim nyog.
Koj Ua Li Cas Xam Lub UPS Ntev Ntev Li Cas?
Cov qauv siv feem ntau rau kev suav lub sijhawm ua haujlwm ntawm UPS yog qhov yooj yim zoo nkauj, tab sis koj yuav tsum paub ob peb yam tseem ceeb ua ntej.
- Nrhiav lub peev xwm ntawm UPS roj teeb hauv ampere teev (Ah). Cov ntaub ntawv no yuav tsum suav nrog UPS cov ntaub ntawv, ntawm nplooj ntawv teev npe, lossis ntawm lub roj teeb nws tus kheej.
- Nrhiav qhov input voltage ntawm UPS.
- Txiav txim siab tag nrho cov load rau UPS hauv watts los ntawm kev ntxiv cov watts siv los ntawm tag nrho cov khoom sib txuas.
- Muab lub roj teeb muaj peev xwm los ntawm qhov hluav taws xob input, ces faib tus lej los ntawm tag nrho cov load.
Piv txwv li, UPS nrog lub roj teeb muaj peev xwm ntawm 150Ah, 10V ntawm cov khoom siv hluav taws xob, thiab lub zog ntawm 700 watts yuav tsum tuav lub sijhawm ua haujlwm ntawm ib ncig ntawm ob feeb (150 x 10, faib los ntawm 700).
FAQ
Kuv yuav xaiv lub hwj chim tsis cuam tshuam li cas?
Xaiv qhov zoo tshaj plaws kev siv hluav taws xob tsis cuam tshuam feem ntau nyob ntawm seb koj siv nws li cas. Piv txwv li, yog tias koj xaiv ib lub UPS rau koj Mac lossis PC, koj yuav tsum xav txog lub cuab yeej wattage, VA rating, thiab runtime, nrog rau qhov loj me.
Cov txiaj ntsig ntawm kev siv UPS yog dab tsi?
Lub hwj chim tsis cuam tshuam, lossis roj teeb thaub qab, tuaj yeem pab tiv thaiv koj lub computer. Nws tuaj yeem muab lub zog thaub qab thaum hluav taws xob tawm mus, ua lub zog "txias" kom cov hluav taws xob ntws mus rau koj lub khoos phis tawj thiab cov khoom siv tsis pub poob los yog surges, thiab txo cov suab nrov nrov.
