Ib lub tshuab tiv thaiv hluav taws xob yuav cawm koj cov khoom siv; ib lub UPS yuav ua qhov ntawd thiab cawm koj txoj haujlwm, ib yam nkaus - lossis cia koj txuag koj qhov kev ua si tom qab muaj hluav taws xob poob qis.

Lub hwj chim tsis tu ncua (UPS) muab ib qho kev daws teeb meem yooj yim: nws yog lub roj teeb hauv lub thawv uas muaj peev xwm txaus los khiav cov khoom siv uas tau ntsaws rau hauv nws cov qhov hluav taws xob AC rau ob peb feeb txog ob peb teev, nyob ntawm koj qhov xav tau thiab kev sib xyaw ntawm cov khoom siv kho vajtse. Qhov no yuav cia koj ua kom cov kev pabcuam hauv internet ua haujlwm thaum lub sijhawm hluav taws xob tsis ua haujlwm ntev, muab tsib feeb rau koj lub khoos phis tawj desktop nrog lub hard drive los ua qhov kaw tsis siv neeg thiab zam kev poob haujlwm (lossis hauv qhov xwm txheej phem tshaj plaws, khiav software kho disk).

Hais txog kev lom zem, nws tuaj yeem muab sijhawm txaus rau koj los txuag koj qhov kev ua si tom qab tsaus ntuj lossis - tej zaum qhov tseem ceeb dua - qhia rau lwm tus hauv kev ua si ua pab pawg uas koj xav tau tawm, yog li koj tsis raug nplua thaum ntxov.

AUPSkuj tseem ua tau zoo li lub cuab yeej tiv thaiv kev kub ntxhov thiab pab koj cov khoom siv thiab lub sijhawm ua haujlwm los ntawm kev txhawb nqa qhov poob qis ib ntus hauv qhov hluav taws xob thiab lwm yam kev tsis sib xws ntawm cov tes hauj lwm fais fab, qee qhov muaj peev xwm ua rau cov khoom siv fais fab computer puas tsuaj. Rau txij li $ 80 txog $ 200 rau feem ntau cov kab ke, UPS tuaj yeem muab kev thaj yeeb nyab xeeb zoo kawg nkaus nrog rau lub sijhawm ua haujlwm ntxiv thiab kev poob tsawg dua.

UPS tsis yog ib yam tshiab. Lawv muaj hnub rov qab ntau xyoo lawm. Tab sis tus nqi yeej tsis tau qis dua thiab qhov ntau ntawm cov kev xaiv yeej tsis loj dua. Hauv qhov kev qhia no, kuv pab koj nkag siab txog yam uas UPS tuaj yeem muab, daws koj cov kev xav tau, thiab muab cov lus qhia ua ntej rau kev yuav khoom. Tom qab xyoo no, TechHive yuav muab cov kev tshuaj xyuas ntawm cov qauv UPS uas tsim nyog rau hauv tsev thiab cov chaw ua haujlwm me me uas koj tuaj yeem ua qhov kev xaiv paub.

Tsis muaj kev cuam tshuam yog lo lus tseem ceeb
Cov UPS tau tshwm sim hauv lub sijhawm uas cov khoom siv hluav taws xob tsis ruaj khov thiab cov drives yooj yim raug pov tseg. Lawv tau tsim los muab lub zog tas mus li - lossis "uninterruptible" - los tiv thaiv ntau yam teeb meem. Lawv tau pom thawj zaug hauv cov racks server thiab siv nrog cov khoom siv network kom txog thaum tus nqi thiab hom ntawv poob qis kom lawv siv tau nrog cov khoom siv hauv tsev thiab chaw ua haujlwm me.
Txhua yam khoom siv uas koj muaj uas poob hluav taws xob thiab muaj lub hard disk nyob hauv nws yuav ua rau muaj cov directory puas tsuaj lossis txawm tias muaj kev puas tsuaj los ntawm lub taub hau drive tsoo rau lwm qhov ntawm lub mechanism. Lwm yam khoom siv uas tau load nws cov firmware tawm ntawm cov chips thiab khiav siv volatile storage kuj tseem yuav ua rau poob cov caches muaj nqis ntawm cov ntaub ntawv thiab xav tau qee lub sijhawm los rov sib sau ua ke.

Xaiv qhov yogUPS
Nrog rau txhua yam ntawd hauv siab, ntawm no yog daim ntawv teev npe uas yuav tsum tau ua thaum soj ntsuam UPS:

1. Koj xav tau lub sijhawm twg nrog fais fab thaum lub sijhawm tsis muaj hluav taws xob? Ntev rau cov khoom siv network; luv rau lub computer kaw.
2. Koj cov khoom siv siv pes tsawg watts? Xam tag nrho cov hwj chim uas koj cov khoom siv txuas nrog xav tau.
3. Koj puas muaj teeb meem fais fab ntau zaus lossis ntev? Xaiv kab sib tham es tsis txhob tos.
4. Yog siv lub computer, puas siv tau PFC? Yog siv tau, xaiv ib lub uas muaj cov zis sine wave ntshiab.
5. Koj xav tau pes tsawg lub qhov hluav taws xob rau kev thaub qab hluav taws xob? Tag nrho koj cov ntsaws tam sim no puas yuav haum rau hauv qhov layout uas muaj?
6. Koj puas yuav tsum tau saib xyuas qhov xwm txheej ntawm UPS ntau zaus txaus lossis kom meej meej tias yuav tsum muaj lub vijtsam LCD lossis software txuas nrog?
