Dab tsi yuav tsum tau ceev faj thaum xaiv qhov hloov pauv hluav taws xob?
Txhawm rau txuas ntxiv lub neej ntawm cov khoom siv hluav taws xob hloov pauv, nws raug nquahu kom xaiv cov qauv nrog 30% tso zis hluav taws xob ntxiv. Piv txwv li, yog tias lub kaw lus xav tau 100W fais fab mov, nws raug nquahu kom xaiv lub zog hluav taws xob nrog lub zog tso zis ntau dua 130W, thiab lwm yam, uas tuaj yeem txhim kho lub neej ntev ntawm lub zog hluav taws xob. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum xav txog qhov chaw ua haujlwm kub ntawm lub zog hluav taws xob thiab seb puas muaj cov khoom siv hluav taws xob ntxiv rau cov cua sov dissipation. Qhov ntsuas qhov tso zis ntawm cov khoom siv hluav taws xob yuav raug txo qis hauv qhov kub thiab txias. Xaiv ntau yam haujlwm raws li daim ntawv thov: kev tiv thaiv kev ua haujlwm: kev tiv thaiv overvoltage (OVP), kev tiv thaiv kub dhau (OTP), kev tiv thaiv overload (OLP), thiab lwm yam. Daim ntawv thov kev ua haujlwm: teeb liab muaj nuj nqi (POWER GOOD, POWER FAIL), chaw taws teeb tswj muaj nuj nqi, telemetry function, parallel muaj nuj nqi, thiab lwm yam tshwj xeeb functions: Fais fab mov kho (PFC), uninterruptible fais fab mov (UPS). Xaiv cov cai tswj kev nyab xeeb thiab cov ntawv pov thawj electromagnetic compatibility (EMC).
Kuv puas tuaj yeem nug yog POWER tuaj yeem siv rau 45 ~ 440Hz? Yog tias muaj, puas muaj lwm yam cuam tshuam?
Hloov cov khoom siv hluav taws xob feem ntau tuaj yeem siv nyob rau hauv qhov ntau zaus no. Txawm li cas los xij, yog tias qhov zaus ntawm kev siv tsawg dhau, nws yuav ua rau txo qis hauv kev ua haujlwm. Piv txwv li, thaum lub input voltage yog 230VAC thiab cov rated load yog siv, qhov efficiency yog 84% thaum lub zaus ntawm input AC zog yog 60Hz. Txawm li cas los xij, yog tias qhov zaus ntawm cov tswv yim AC lub zog raug txo mus rau 50Hz, qhov ua tau zoo yog 83.8%; Thaum nws siab dhau lawm, nws yuav ua rau PF tus nqi ntawm cov qauv nrog PFC muaj nuj nqi txo, thiab tseem ua rau kom cov dej ntws tawm tam sim no. Piv txwv li, thaum lub input AC zaus yog 60Hz thiab cov ntsuas load yog 230VAC, lub hwj chim yam yog 0.93 thiab cov to tam sim no yog 0.7mA; Thaum lub input AC zaus yog 440Hz, lub zog qhov tseem ceeb txo mus rau 0.75 thiab cov to tam sim no nce mus rau 4.3mA.
