A4VSO泵具有泵具有噪音低、體積小、自吸能力好、可靠性高等優點。在閉式系統上應用，油泵變量過零位時一般柱塞泵都有托盤現象，唯獨D-A4VSO泵有效解決此類問題，因補油泵、控制泵可以串接、控制閥可以集成在泵蓋上，其結構非常緊湊;另外，比例泵均帶有位移傳感器閉式反饋回路，其零位控制精度非常高。廣泛應用于：冶金行業、鍛壓行業、船舶行業、船舶等等領域。A4VSO系列規格有40、71、125、180、250:;變量形式有恒壓，恒功率、液動、負載感應、比例、伺服、壓力流量復合控制形式;有開式系統泵和閉式系統泵。A10-FR01B-12,A10-FR01C-12,A10-FR01H-12,

照明燈、觀片燈和電動門等可以不從IT系統取電。圖4為采用隔離電源系統的手術室或ICU配電系統圖。絕緣監測儀時刻監測IT系統的絕緣狀態，并在系統出現故障時給出報警信號，外接的報警與顯示儀通過RS485接口與絕緣監測儀進行實時的數字通信，顯示絕緣監測儀的檢測結果，并在報警時發出聲光報警信號。除了絕緣監測設備外，系統還配置了絕緣故障測試儀和絕緣故障評估儀。絕緣故障測試儀能夠在線查找故障發生的回路，它和絕緣監測儀一起工作，當絕緣監測儀探測到系統絕緣故障后，絕緣故障測試儀立即開始故障定位，由絕緣故障評估儀周期性地送出一個特殊的測試電流，測試電流流經故障部位，由電流互感器探測，并由電子評估儀對故障回路進行評估，評估的結果送報警與顯示儀中顯示。
