Cov teeb meem tshwm sim hauv kev siv hluav taws xob hloov hluav taws xob
1. Kuv yuav tsum xyuam xim rau dab tsi thaum xaiv cov khoom siv hluav taws xob hloov?
Teb: Yuav kom ncua lub neej kev pab cuam ntawm lub switching fais fab mov, nws yog pom zoo kom xaiv ib tug qauv nrog ntau tshaj 30% rated tso zis zog. Piv txwv li, yog tias lub kaw lus xav tau 100W lub zog hluav taws xob, 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 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 lub hwj huam mov yuav raug txo qis ntawm qhov kub thiab txias ambient. Xaiv ntau yam haujlwm raws li daim ntawv thov: kev tiv thaiv kev ua haujlwm: kev tiv thaiv dhau-voltage (OVP), kev tiv thaiv kub dhau (OTP), kev tiv thaiv dhau kev thauj khoom (OLP), thiab lwm yam. Chaw taws teeb tswj muaj nuj nqi, telemetry muaj nuj nqi, parallel muaj nuj nqi, thiab lwm yam tshwj xeeb functions: fais fab kev kho (PFC), uninterruptible fais fab mov (UPS). Xaiv cov cai tswj kev nyab xeeb uas yuav tsum tau muaj thiab daim ntawv pov thawj electromagnetic compatibility (EMC).
2. POWER puas siv tau ntawm 45 ~ 440Hz? Yog tias muaj, puas muaj lwm yam cuam tshuam?
A: Hloov cov khoom siv hluav taws xob feem ntau tuaj yeem siv rau hauv qhov ntau zaus no. Txawm li cas los xij, yog tias qhov zaus tsawg dhau, qhov ua tau zoo yuav txo qis. Piv txwv li, thaum lub input voltage yog 230VAC thiab qhov ntsuas load yog 23{{10}}VAC, qhov ua tau zoo yuav yog 84% thaum lub input AC zaus yog 60Hz, tab sis yog tias input AC zaus raug txo mus rau 50Hz, qhov ua tau zoo yuav yog 83.8%. Yog tias nws siab dhau lawm, PF tus nqi ntawm cov qauv nrog PFC muaj nuj nqi yuav txo qis, thiab nws tseem yuav ua rau kom cov xau tam sim no. Piv txwv li, thaum lub input AC zaus yog 60Hz, lub hwj chim yog 0.93 thiab cov to tam sim no yog 0.7mA ntawm 230VAC thiab rated load; Thaum qhov zaus ntawm cov tswv yim hloov pauv tam sim no yog 440Hz, lub zog hluav taws xob txo qis rau 0.75 thiab cov xau tam sim no nce mus rau 4.3mA.
3. Yog tias xav tau 24V voltage, tab sis Gaoxin tsis muaj cov qauv no, puas tuaj yeem siv ob lub 12V series?
Teb: Yog, tab sis nws yuav tsum tau muab sau tseg tias * me me tam sim no nyob rau hauv series qauv yog qhov siab tshaj plaws tam sim no yuav tsum tau los ntawm tag nrho cov system tom qab series kev twb kev txuas. Tsis tas li ntawd, txhawm rau tiv thaiv qhov muaj peev xwm ntawm kev puas tsuaj sab hauv los ntawm cov khoom siv hluav taws xob thaum pib, nws tau qhia tias SPU cov zis davhlau ya nyob twg txuas nrog rau tib lub sijhawm nrog lub diode.
