style="font-size:16px">1.輸出電壓穩(wěn)定：采用高頻倍壓電路，應(yīng)用PWM脈沖寬度調(diào)制技術(shù)和電壓電流雙閉環(huán)反饋技術(shù)，提高電源調(diào)整率和負(fù)載調(diào)整率，使電壓穩(wěn)定度高，紋波小。全量程平滑調(diào)壓，輸出電壓精度高。主機電壓表直接顯示加載在負(fù)載上的電壓值，無需外加分壓器，接線操作簡單。電壓分辨率0.1kV，電流分辨率1uA。<br />2.保護全面：保護功能齊全，具有零位保護、過壓保護、過流保護、擊穿保護，保護電路選用納秒級傳感器，動作迅速可靠，有效保障人身及設(shè)備安全。<br />3.0.75U功能：增設(shè)智能高精度0.75U功能一鍵按鈕，按下此按鈕，電壓電流自動跳轉(zhuǎn)至0.75U狀態(tài)，利于氧化鋅避雷器的測試。<br />4.零起升壓：升壓電位器零起升壓，采用進口多圈電位器，升壓過程平穩(wěn)，調(diào)節(jié)精度高。<br />5.過壓設(shè)定：過壓整定選用數(shù)字撥碼開關(guān)，操作簡單，并具有較高的整定精度。<br />6.一體式設(shè)計：選用一體式設(shè)計方案，主機和倍壓筒放置在一個機箱內(nèi)。選用進口高頻高壓整流二極管，使倍壓筒體積小巧，提升整機效率，便于攜帶。<br />7.性能可靠：關(guān)鍵器件選用高性能進口元件，倍壓筒外表涂特種絕緣材料，電氣性能好、防潮能力強、無泄漏。<br />8.操作簡單：儀器界面各功能按鍵，布局合理，指示清晰，易學(xué)易用。</span></p><p><span style="font-size:16px"><img alt="" src="http://img71.chem17.com/9/20191108/637087969532478182250.jpg" style="width:800px" /></span></p> <div
