PDU sawv rau chav tso hluav taws xob, uas yog cov cuab yeej tseem ceeb hauv cov chaw nruab tam sim no thiab chav rau neeg rau zaub mov. Nws ua haujlwm ua lub koom haum tswj hwm hluav taws xob uas coj hwj chim rau ntau cov khoom siv, kom ua haujlwm tsis muaj kev cuam tshuam. PDUs yog tsim los tuav ob qho tib si-theem thiab peb-theem zog, nyob ntawm cov kev xav tau ntawm cov khoom lawv muaj hwj chim. Ib leeg fais fab zog yog hais txog hluav taws xob muab hluav taws xob uas siv ib qho WaveFormform tau faib hluav taws xob. Nws yog feem ntau siv nyob rau hauv tsev neeg thiab cov lag luam me, qhov twg qhov kev thov kom muaj zog yog tsawg. Ntawm qhov tod tes, peb-theem fais fab hluav taws xob siv peb cov nthwv kom faib lub zog, tso cai rau cov hluav taws xob ntau dua thiab cov zog tawm. Hom hluav taws xob no feem ntau yog siv rau hauv cov chaw muaj teeb tsa thiab cov chaw muag khoom loj. Txhawm rau sib txawv ntawm ib leeg-theem thiab peb-theem PDUs, ib qho xav tau xav txog ob peb yam tseem ceeb:
1. Kev tawm tsam voltage: ib-theem pdus feem ntau muaj ib qho kev tawm tswv yim voltage ntawm 120V-248V-480V.
2. Tus naj npawb ntawm theem: Ib leeg-theem Pd me faib hluav taws xob siv ib theem, thaum peb-theem pdus faib lub zog siv peb theem.
3. Qhov hluav taws xob teeb tsa: Ib Leeg-theem PDUs muaj cov hluav taws xob uas tau tsim rau ib-theem zog, thaum peb-theem pdus uas tau tsim rau peb-theem zog.
4. Lo tau muaj peev xwm: Peb-theem PDU yog tsim los tuav cov khoom lag luam ntau dua li ib theem pdus. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm ib theem-theem thiab peb-theem PDUs nyob rau hauv lawv cov lus qhia voltage, naj npawb ntawm theem, qhov hluav taws xob kev teeb tsa, thiab muaj peev xwm thauj khoom muaj peev xwm. Nws yog qhov tseem ceeb uas yuav tsum xaiv PDU uas tsim nyog raws li lub zog uas yuav tsum tau ntawm cov khoom siv nws yuav siv zog txhim khu kev qha thiab ua haujlwm zoo.
