SBW SBW、DBW系列單、三相全自動補償式電力穩壓器采用國際先進的補償技術設計制造。 當電網電壓波動或負載電流變化時， 能自動保持輸出電壓穩定， 以保障用電設備正常運行。 與其它型式的穩壓器相比較，具有容量大、效率高、無波形畸變，使用維護簡便、運行可靠， 在輸入電壓范圍低端時仍能全容量輸出。具有過壓、過流、開機相序等保護。 This product is designeg and developed with the international advanced compensation technol- ogy .It can keep the output voltage in steady state automatically when the network voltage fluctuat- ed or the load current varied, which can ensure the consumer run smoothly. It has the advantage of large capacity、 high efficiency、 no waveform distortion、simple operation and maintenance、 reliabie running、full-capacity output under tower input voltage if compared with other voltage sta- bilizer. It is provided with over-voltage、over-current、phase sequence and so on protection function. 適用于小型工廠全廠，大、中型工礦企業車間、部門供電、可廣泛用于工礦企業、油田、 鐵路、建筑工地、學校、醫院、賓館、科研等部門的精密機床、精密儀器、試驗裝置、電梯、 進口機電設備及生產流水線設備穩壓，也適用于電源電壓低，波動幅度大的低壓電網未端的 用戶。 It is suitable for electric supply in small-sized plant、workshop and department inmiddle、large- sizde mining enterprise,it can be widely used in the precision machine tool、precision instrument, test device、elevator、imported electromechanical device、production flow-line in the mining ent- erprise、oil field、railway、building site、school、hospital、hotel、scientificresearch department and so on, it is also suitable for the user in the LV electric network end with low power voltage and big wave range.
