隔離電壓，是隔離型DC/DC電源模塊的一個(gè)重要指標(biāo)，一般分1000VDC、1500VDC、2000VDC、3000VDC、6000VDC等規(guī)格，是指在一定時(shí)間內(nèi)（通常是1秒）電源模塊所能承受的、施加在輸入端和輸出端之間的比較高電壓。隔離電壓等級(jí)越高，電源模塊內(nèi)部的保護(hù)器件和設(shè)計(jì)工藝要求就越高，從根本上講，就是成本越高。那么怎樣選擇合適的隔離電壓呢？<span style="font-size:12px;">電源模塊的隔離電壓，需要根據(jù)應(yīng)用場(chǎng)合來(lái)選擇。一般場(chǎng)合使用對(duì)電源模塊隔離電壓要求不是很高，但是更高的隔離電壓可以保證模塊電源具有更小的漏電流，更高的安全性和可靠性，并且EMC特性也更好一些，加之嵌入式系統(tǒng)器件集成度高，封裝小，相對(duì)比較脆弱，因此一般應(yīng)用業(yè)界，普遍的隔離電壓水平為1500VDC或以上。但在一些特殊的行業(yè)，比如醫(yī)療，戶外通信基站，高壓電力等，對(duì)電源模塊的隔離度要求則更高。</span>
