1747-L531 不能正常調壓（碳刷不調節）
1.線路板壞或電機壞
排除：更換線路板壞或電機
2.無輸入電源
排除：檢查輸入電源是否正常（接線是否牢固，是否有缺相等）
四、空載正常但帶負載不能正常工作
1.零線接觸不良
排除：檢查零線
2.零線錯接成地線
排除：更換接好零線
3.負載大，造成輸入電壓低于穩壓范圍
排除：增大穩壓電源容量，對于感性負載按負載容量的2～3倍選取。
4.輸入電線太長或截面積不夠，線路壓降大
排除：采用銅芯電線，或適當增加導體的截面積。
五、帶載后產品溫升高，線圈有焦味
5.負載過重，超負荷運行和輸入電壓低（非補償式穩壓器在輸入電壓低于198V時，要降額使用）
排除：減小負載或選用大容量的穩壓電源
六、產品機殼漏電
地線和零線接反
排除：將地線和零線分別按正確方法接入
七、產品有輸出，但三相輸出誤差較大
1.三相輸入電壓誤差大或三相輸出負載不均勻
排除：檢查輸入電壓和三相輸出輸出負載情況
2.線路板上輸出電位器調節有誤差
排除：調節輸出電位器，使每相輸出相電壓為220V（調節電位器時，以火線與零線間電壓為準）
八、開機后不能正常啟動
碳刷處于線圈低端，常發生在停電后來電，如果停電前電壓過低，當電壓正常再來電時由于線圈也是感性負載，電流沖擊過大易造成保險絲燒壞導致產品不能正常啟動
排除：先關機，檢查保險絲是否燒壞，用螺絲刀將碳刷撥到線圈中間位置，再開機
九、穩壓電源內部有異常噪音
1.碳刷走動時發出明顯的“咔哧”噪音或碳刷與線圈之間打火
1）碳刷與線圈接觸不良造成，產品積塵或其它原因造成線圈磨面不平、不清潔或氧化
排除：清除灰塵或其它雜質，如不能消除，用細砂紙將線圈氧化部分及碳刷小心打磨，使碳刷與線圈接觸良好。
2.線圈發出噪聲
1）負載大或鐵芯松動
排除：減小負載或更換線圈
3.電機噪聲
1）齒輪磨損或脫位
排除：更換電機或配合裝好齒輪
4.輸出接觸器響
1）接觸器鐵芯有雜物或污垢、灰塵
排除：擦除干凈或更換接觸器
注意事項
為了確全，外殼務必可靠接地（本機外殼設有接地裝置）。
