Xaiv qhov tsim nyog UPS fais fab mov yuav tsum xub txiav txim peb lub ntsiab lus:

1. Koj yuav tsum siv cov cuab yeej twg? Puas muaj lub cev muaj zog hauv cov khoom siv?
2. Koj cov khoom siv fais fab yog dab tsi? Dab tsi yog qhov yuav tsum tau voltage rau V input?
3. Ntev npaum li cas koj yuav tsum tau tua hluav taws xob rau thaub qab?

Tom qab lees paub peb lub ntsiab lus no, koj tuaj yeem tshawb xyuas cov rooj zaum raws li cov ntsiab lus ntawm peb lub ntsiab lus.
1. Yog tias cov khoom siv tsuas yog cov khoos phis tawj zoo tib yam, cov servers thiab lwm yam khoom siv, ces xaiv lub zog ntawm UPS fais fab mov raws li 1.5 npaug ntawm lub zog tag nrho ntawm cov khoom siv thauj khoom no.
Yog hais tias muaj inductive loads xws li motors, compressors, dej twj, cua txias, khoom siv fais fab, thiab lwm yam, lub hwj chim ntawm lub uninterruptible UPS fais fab mov raug xaiv raws li 5 npaug ntawm tag nrho cov hwj chim ntawm cov khoom load.
2. Qhov loj ntawm cov khoom siv fais fab yog koj lub hauv paus rau kev kwv yees lub zog ntawm UPS fais fab mov. Xaiv lub UPS fais fab mov raws li ntau yam hais hauv thawj qhov chaw.
Tsim los rau qhov yuav tsum tau muaj qhov voltage, uas yog qhov input voltage ntawm koj cov khoom siv thauj khoom, yuav muaj 220VAC 380VAC 110VAC (muaj tsawg dua hauv Suav teb av loj).
3. Lub sijhawm ntawm lub zog hluav taws xob uas yuav tsum tau txiav txim siab seb koj li UPS fais fab mov xaiv lub tshuab txheem (cov qauv siv roj teeb) lossis cov qauv roj teeb sab nraud (lub tshuab mus sij hawm ntev).

Yog tias koj tsis xav tau lub sijhawm thaub qab ntev rau cov hluav taws xob hluav taws xob, tsuav yog qhov hluav taws xob tiv thaiv hluav taws xob yog ob peb feeb thiab muaj lub sijhawm kaw txaus, ces xaiv lub tshuab txheem,
Yog tias koj xav tau lub sijhawm thaub qab ntev, ces xaiv lub tshuab ua haujlwm ntev los txuas nrog lub peev xwm loj UPS fais fab mov roj teeb. Cov kev suav tshwj xeeb tuaj yeem ua raws li cov qauv no [( roj teeb muaj peev xwm * roj teeb voltage * naj npawb ntawm cov roj teeb) / load zog] * fais fab tuag = load Lub sijhawm yog teev.
