特種電源即特殊種類的電源。所謂特殊主要是由於衡量電源的技術指標要求不同於常用的電源,其主要是輸出電壓特別高,輸出電流特別大,或者對穩定度、動態響應及紋波要求特別高,或者要求電源輸出的電壓或電流是脈衝或其它一些要求。這就使得在設計及生產此類電源時有比普通電源有更特殊甚至更嚴格的要求。特種電源一般是為特殊負載或場合要求而設計的,它的應用十分廣泛。主要有:電鍍電解、陽極氧化、感應加熱、電力操作、電力試驗、環保除塵、空氣凈化、食品滅菌、激光紅外、光電顯示等。而在國防上,特種電源更有普通電源不可取代的用途,主要用於:雷達導航、高能物理、等離子體物理及核技術研究等。

熟悉可編程序控制器、功能表圖及有關的編程語言有利於縮短編程時間,因此,工程設計選型和估算時,應詳細分析工藝過程的特點、控制要求,明確控制任務和範圍確定所需的操作和動作,然後根據控制要求,估算輸入輸出點數、所需存儲器容量、確定可編程邏輯控制器的功能、外部設備特性等,後選擇有較價格比的可編程邏輯控制器和設計相應的控制係統。
