class=\"detail-desc-decorate-content\"\u003e購買前，請自行確定您的電器電壓和功率是否與電源匹配，插頭規格是否相容，插頭極性是內正外負還是外正內負（這一點非常重要，如果正負極接反，機器會燒毀）。\u003cbr\u003e \u003cbr\u003e由於我對市面上現有適配器的性能並不滿意，因此設計了這款產品，主要面向HIFI音訊產品，旨在使音樂背景更加安靜、動態和智慧。其高動態電流源自大漣波電解電容和超低內阻穩壓IC。當然，它也能為路由器、攝影機等家用電器供電，價格也相當實惠。\u003cbr\u003e\u003cbr\u003e電源供應器的總輸出功率為10瓦，電流 = 總功率 \/ 電壓\u003cbr\u003e以下目前參數是使用負載計和示波器測量所得的實際目前值，未進行任何調整：\u003cbr\u003e 5V：電流約1600毫安培\u003cbr\u003e6V：電流約為1300毫安培\u003cbr\u003e9V：電流約為1000毫安培\u003cbr\u003e12V：電流約 830 mA\u003cbr\u003e 15V：電流約 660 mA\u003cbr\u003e 24V：電流約410毫安培\u003cbr\u003e30V：電流約330毫安培\u003cbr\u003e \u003cbr\u003e峰值電流為3A，這與大電容有關。 9V、12V、15V濾波器具有25V、3300UF的大電解耐壓；24V和30V濾波器具有50V、3300UF的大電解耐壓。\u003cbr\u003e輸出插頭：直插式5521和彎頭式5525兩種形狀，品質相同，預設出貨為直插式5521；如需彎頭式，請聯絡客服。插頭極性預設為正負極，帶磁環，線材為屏蔽線，最大電流6A，台灣製造。\u003cbr\u003e\u003cbr\u003e有些顧客和朋友反映，用萬用電表測得的輸出電壓高於額定電壓（例如，購買時標稱5V，實際測得5.2V），這是正常現象。空載時電壓必然會更高。載入後，由於線路電壓降，會有損耗。電器本身的輸出電壓約為5.1V，非常標準。藍色電位器可調整到5.0V，但調節範圍並不合理。 \u003cbr\u003e它與普通適配器有何不同？請參考下圖說明： \u003c\/p\u003e\u003c\/div\u003e\n\u003cdiv class=\"detailmodule_text\"\u003e\u003cp

class=\"detail-desc-decorate-content\"\u003e最近有評論將此電源與開關電源聯繫起來。什麼是開關電源？您的手機充電器是開關電源，飛利浦檯燈的電源也是開關電源。無論開關電源的性能多麼優良，其峰峰值紋波都在100毫伏左右，而線性電源可以輕鬆控制在10毫伏以下。對於合格的隨身聽、收音機、解碼器、耳機放大器或前級放大器而言，低於10毫伏的電源紋波已經足夠低，低到即使是最靈敏的耳機或揚聲器也無法察覺。如果使用我們的電源（峰值漣波在2毫伏以內）仍然無法解決雜訊問題，請檢查電源以外的其他因素。
