走線阻抗大。電源模塊輸出與負(fù)載連接必然要有一段PCB走線，走線越長(zhǎng)、走線越窄則它的等效電阻越大。等效電阻可以認(rèn)為是串聯(lián)在負(fù)載的工作回路中，將起到分壓作用，因此導(dǎo)致負(fù)載兩端的電壓小于模塊的輸出電壓。此外，除了走線問(wèn)題還有很多情況起到類似的作用，比如焊點(diǎn)接觸不良導(dǎo)致等效電阻增加，線路氧化或腐蝕導(dǎo)致等效電阻增加。<span style="font-size:12px;">防反接二極管。很多產(chǎn)品的AC和DC部分是不在一塊板上的，在生產(chǎn)或終端客戶使用中不可避免涉及到插拔電源連接器的情況。為防止此過(guò)程中的反接導(dǎo)致的硬件損壞，常串入一只二極管解決。以壓降0.7V的二極管為例，b1 b2間的電壓將比a1 a2間電壓小0.7V，這也就是上面所討論的輸入電壓偏低的情況，可以通過(guò)選擇壓降低的管子或者直接提高a1 a1間電壓的方法解決。</span> </p> <p> 具有可視化遠(yuǎn)程控制、故障主動(dòng)報(bào)警、防盜監(jiān)控以及擴(kuò)展其它傳感應(yīng)用等功能。北京智能路燈電-源品牌好嗎</p><p
