在PLC控制系統(tǒng)中，電源占有極重要的地位。電網(wǎng)干擾串入PLC控制系統(tǒng)主要通過PLC系統(tǒng)的供電電源（如CPU 電源、I/O電源等）、變送器供電電源和與PLC系統(tǒng)具有直接電氣連接的儀表供電電源等耦合進(jìn)入的?，F(xiàn)在，對(duì)于PLC系統(tǒng)供電的電源，一般都采用隔離性能較好電源，而對(duì)于變送器供電的電源和PLC系統(tǒng)有直接電氣連接的儀表的供電電源，并沒受到足夠的重視，雖然采取了一定的隔離措施，但普遍還不夠，主要是使用的隔離變壓器分布參數(shù)大，抑制干擾能力差，經(jīng)電源耦合而串入共模干擾、差模干擾。所以，對(duì)于變送器和共用信號(hào)儀表供電應(yīng)選擇分布電容小、抑制帶大（如采用多次隔離和屏蔽及漏感技術(shù)）的配電器，以減少PLC系統(tǒng)的干擾。

此外，位保證電網(wǎng)饋點(diǎn)不中斷，可采用在線式不間斷供電電源（UPS）供電，提高供電的安全可靠性。并且UPS還具有較強(qiáng)的干擾隔離性能，是一種PLC控制系統(tǒng)的理想電源
