中發(fā)工業(yè)DOLD 63818 繼電器原裝進口
LED燈的驅(qū)動器里面都有一個電容，可以把電容理解成一個容量很小的充電電池：當電容內(nèi)通過電流時，電容會持續(xù)充電——充滿電以后，電容會一次性將儲存的電能全部釋放。LED燈閃爍，就屬于后一種情況：電容充電的過程中，燈是熄滅的——由于電容內(nèi)部電流較小，導致充電速度很慢，所以用肉眼是可以看到電燈熄滅的。當電容充滿電后，一次性釋放電能，會點亮電燈。但是由于儲存的電能較少，電燈很快就會熄滅——不停的重復充電、放電，肉眼看到的，就是燈閃爍。

一般規(guī)定：吸合電壓不得低于線圈額定電壓值的85%，釋放電壓則不高于線圈額定電壓值的70%。操作頻率接觸器的操作頻率指每小時允許操作次數(shù)的值。每小時允許操作次數(shù)可分為：1次/3次/12次/30次/120次/300次/600次/h，1200次/h和3000次/h。操作頻率影響到交流接觸器的電壽命，還影響到交流接觸器線圈的溫升。工作制接觸器有四種工作制，分別是8h工作制、不間斷工作制，斷續(xù)周期工作制和短時工作制。
