\r產(chǎn)品選用注意事項(xiàng)<\/span><\/span><\/span><\/strong>\r<\/p>\r

\r
• \r選擇產(chǎn)品時(shí)，應(yīng)根據(jù)負(fù)載的性質(zhì)不同，在電流檔次上留有不同的余量<\/span>。<\/span>（阻性<\/span><\/span>負(fù)載<\/span>，可按2-3<\/span>倍負(fù)載電流選取。感性或容性負(fù)載<\/span>時(shí)，可按3-4<\/span><\/span>倍負(fù)載電流選取<\/span><\/span>）<\/span>。<\/span><\/span><\/strong>\r<\/li>\r
• \r根據(jù)負(fù)載電流與環(huán)境溫度的關(guān)系，當(dāng)環(huán)境溫度較高或散熱條件欠佳時(shí)。<\/span>應(yīng)增加電流容量<\/span>。<\/span>為防使用時(shí)負(fù)載短路，要求在負(fù)載回路中串接與本產(chǎn)品<\/span><\/span><\/span><\/strong>相應(yīng)的快速斷路開(kāi)關(guān)或快速熔斷器。<\/span><\/span><\/strong><\/span>感性負(fù)載時(shí)，應(yīng)在輸出端并接壓敏電阻，以防過(guò)壓時(shí)損壞晶閘管。<\/span>壓敏<\/span>電阻(MOV<\/span>)<\/span>的選配：240V檔時(shí)選430-470V，440V檔時(shí)選680-750V，<\/span>660V檔時(shí)選1100-1200V。或配本廠(chǎng)生產(chǎn)的交流過(guò)壓保護(hù)吸收器。<\/span><\/span><\/strong><\/span>\r<\/li>\r
• \r安裝時(shí)，要求散熱器與本產(chǎn)品接觸面之間必須平整、光潔,并在其表面涂<\/span>上一層導(dǎo)熱硅脂**再將套上平墊圈、彈簧墊圈的螺絲對(duì)稱(chēng)擰緊固定。<\/span> <\/span><\/span><\/strong>\r<\/li>\r<\/ul>\r
