COJ series-mus tib seem uas PFC hwj huam tau

Aug 04, 2015

Feem ntau AC220V siab voltage rho tawm tswv yim ces tau txog electrolytic capacitors input fais 1W = 1UF, AC110V1W = 2UF PFC fais fab muaj peb plaub tam sim no ntawm lub lag luam: ib lawm uas tsis muaj PFC zog tau them Circuit Court, Its PF value General hauv 0.65 ncig; II hom muaj tsis tau qhov twg los zog tau them PFC Circuit Court ntawm, yog tsis muaj qhov hwj huam tau them cov nqi kho teeb, tseem hu ua lub Rooj Tswjhwm Saib Circuit Court txaus tab tom siv dav tshaj kev ntseeg tau zoo tshaj plaws, PF value General hauv 0.92 ncig; kuj muaj peb hom no uas muaj qhov dhia hom 7527/6561 Circuit Court ua kev, yog muaj qhov hwj huam tau raug mob, hu ua APFC Circuit Court hauv lub AC220V, AC110V yuav nrog nrog tau txog Electrolytic Capacitor, xaiv 1W = 1.5UF. PF mus txog tus nqi rau cov programme kim ib nyuag tsawg tshaj ob zaug kev ntseeg tau 1 0.99, tiam sis. Vim li ntawd lub xaiv thib ob yog xav paub ntxiv. Passive Circuit Court PFC: los yog hav-PFC Circuit Court DC khiav hauj lwm voltage ntau yog ib nrab lub ncov AC input voltage. Yog hais tias cov tswv yim no 220V, thiab tus siab kawg yog 220 * 1.414 = 312V, ib nrab voltage ncov yog 156V, yog raws li nthwv dej tso zis tsis-cais tsis txo ib nrab-yoj ntawm yoj.

Txoj kev LED teeb lub hwj huam hlaws dai series txog cov hlua 45 feem. Vim li no, xav tau ntau zog los teeb lub hlaws series tsis tau muaj tsawg heev, los yog tsis mus rau qhov zoo ua hauj lwm lub xeev, raug rho tawm fais fab mov txog tooj nrog rau cov khub uas koj lem winding, ntau npaum li cas, hwj chim yuav tsum ua kom mus tso zis ntau zog. Hauv Cheebtsam ntawm qhov cov movies voltage khwv tam sim no thaum me me kom sov tau kawg ntawm ntev, nkawd lub neej yuav luv. Txoj kev LED teeb lub hwj huam hlaws dai pauv rhiab heev AC tuaj rau ntau lub luj lub teeb txob. Electrolytic capacitors no yuav tsum raug siv rau koj voltage los txo cov zis voltage AC luj kom tswj tau, nyiaj phab siab tau txog electrolytic capacitors yuav tsis yog tsawg heev, ntim thiab tso zis tam sim no rau 1UF < 1.5MA yuav tsum flashing otherwise LED. Tsis cais input xaiv thiab cais cov qub siab voltage Electrolytic Capacitor, tso zis 1UF capacitor xaiv < 6MA. dimming LED fais fab mov rau electrolytic capacitors ntawm cov zis kom tau raws li cov 1UF < 0.5MA.
