Sorensen XHR 系列
XHR 系列是緊湊型直流電源。半機架尺寸可輸出 1000 W 功率。該系列產品有 18 個 1 kW 的型號可供選擇。其機型小巧、功能，對于需要高功率和寬輸出電壓或電流調節范圍的 OEM 應用是理想的選擇。其半機架的寬度有利于配置。XHR 可堆疊，占用面積小，帶前面板接線柱，電流需求低，可插入標準的 120 VAC，15 A 線路。其采用零電壓“軟開關”技術，消除了開關切換瞬變效應，達到高效率、低噪聲和高可靠性的優點。XHR 可對低電流耗 （僅11A 20 VAC/1000 W）進行功率因數校正，并減少輸入電流諧波的產生。
半機架寬的 XHR 非常適合在測試系統設備控制臺中與另一個半機架儀器“搭配”，無需空面板，同時不會占用垂直機架空間。XHR 提供后面板和/或前面板連接器，可輕松、靈活地集成到系統中。

Line drop is subtracted from total voltage available at supply output. 7. Typical efficiency at 115 Vac input and rated output power. 8. Apply accuracy specifications according to the following voltage program accuracy example: Set a model 20-50 power supply to 10 V. The expected result will be within the range of 10 V ± 75 mV ± 0.12% of the set voltage of 10 V. | |||||
