style="text-indent:25px">電源在電子系統(tǒng)中，猶如人的心臟一樣，十分重要。選用合適的電源模塊，可省去電源設(shè)計(jì)、調(diào)試、生產(chǎn)、測(cè)試、老化、物料管理等諸多方面的麻煩，縮短產(chǎn)品開(kāi)發(fā)周期，提高產(chǎn)品的整體可靠性和可維護(hù)性。那么該如何選擇呢？電源模塊按照輸入主要分為兩大類，AC和DC，當(dāng)輸入為交流電是選擇AC-DC電源模塊，交流輸入一般常見(jiàn)的有110VAC和220VAC兩種；當(dāng)輸入為直流時(shí)，選擇DC-DC電源模塊。隔離，可切斷浪涌等干擾信號(hào)的傳播路徑，其優(yōu)勢(shì)如：保護(hù)人員、負(fù)載設(shè)備免遭輸入端的瞬態(tài)高壓損害；去除隔離電路之間的接地環(huán)路以及改善抗干擾能力；在系統(tǒng)中輕松完成輸出接線，而不與主接地發(fā)生問(wèn)題。虹口區(qū)充電電源規(guī)格是多少電源模塊基于開(kāi)關(guān)電源技術(shù)，采用較好的原材料，結(jié)合特殊的模塊化生產(chǎn)工藝制作而成。</p><div
