SZBW系列三相智能无触点稳压电源(简称SZBW稳压电源)额定功率常规范围为10KVA至2000KVA，常规稳压范围为380V±20%，稳压精度高达1%(具体性能可参考产品参数)。

The rated capacity of SZBW series three phase SCR voltage regulator (hereinafter referred to as SZBW voltage regulator) ranges from 10KVA to 2000KVA for normal products. The normal voltage regulation range is 380V+20% while the output voltage accuracy is ±1%.(Detailed product performance is shown in product specifications).

SZBW稳压电源适用于对电压精度要求非常高的设备仪器，或是对稳压响应速度快，噪音要求较高的场所。此系列产品具有响应速度快、稳压精度高、无噪音、效率高、无波形畸变、电压调节平稳、可长期连续工作，设有过欠压保护、过流保护、缺相、相序保护及机械故障保护，使用安装方便，运行可靠等优点。

SZBW voltage regulator is usually used with electrical equipment which is allergic to voltage accuracy. Also, it could be applied in places where noise is unacceptable and where there is a high demand of voltage regulation reaction speed. This type voltage regulator features in fast response speed, high voltage regulation accuracy. no noise, high efficiency, no additional waveform distortion, sound voltage regulation performance, suitability for constant work. It is designed with various protection functions, including over-voltage, under-voltage, over- current,phase lack,phase failure,and mechanic fault etc
