BWM W2 和 WN3 是由BWM（假設是一家專注于電力轉換設備生產的制造商）推出的兩種型號的雙電源自動轉換開關。這種類型的開關主要用于電力系統中，當主電源出現故障或切換時，能夠確保不間斷的電力供應，以保護關鍵負載和設備免受電壓波動、斷電等影響。 W2型號可能是具有基本功能的經濟型產品，它可能具備快速切換、短路保護、過載保護以及一些基本的監測報警功能，適用于對供電質量要求相對較低的應用場景。 而WN3型號則可能為高級或專業級的產品系列，它在W2的基礎上增加了更多的高級特性，如更高的可靠性、更快的轉換速度、更為精確的電壓和頻率檢測、更強的防雷擊及電磁兼容性能，以及遠程監控和控制能力，適用于對供電連續性和穩定性有較高要求的重要設施或工業自動化系統中。具體的技術參數、應用范圍和優勢需參考BWM公司提供的詳細產品規格說明和技術文檔。
