1．輸出電壓值能夠在額定輸出電壓值以下任意設(shè)定和正常工作。
2．輸出電流的穩(wěn)流值能在額定輸出電流值以下任意設(shè)定和正常工作。
3．直流穩(wěn)壓電源的穩(wěn)壓與穩(wěn)流狀態(tài)能夠自動(dòng)轉(zhuǎn)換并有相應(yīng)的狀態(tài)指示。
4．對(duì)于輸出的電壓值和電流值要求的顯示和識(shí)別。
5．對(duì)于輸出電壓值和電流值有要求的直流穩(wěn)壓電源，一般要用多圈電位器和電壓電流微調(diào)電位器，或者直接數(shù)字輸入。
6．要有完善的保護(hù)電路。直流穩(wěn)壓電源在輸出端發(fā)生短路及異常工作狀態(tài)時(shí)不應(yīng)損壞，在異常情況后能立即正常工作。
