SBW系列三相全自动补偿式电力稳压器是本公司引进吸收西欧先进技术，同时结合我国国情，为稳定交流电压而设计，当外界的供电网络电压波动或负载变化而造成电压波动时，能自动保持输出电压的稳定。本系列产品与其它型式的稳压器相比，具有容量大、效率高、无波形畸变、电压调节平稳等优点，适用负载广泛，能承受瞬时超载，可长期连续工作，手动/自动切换，设有过压保护、缺相、相序保护及机械故障自动保护，以及体积小，重量轻，使用安装方便，运行可靠等优点。
　　The design of SBW series three-phase automatic compensation electron voltage regulator has introduced western advanced techniques and combined with national condition to regularize AC voltage. When voltage fluctuates because of external power web voltage undulation or load change, the series can automatically maintain stability of output voltage. Compare with other style of manostats, the series feature large volume, high efficiency, no waved distortion, stable voltage regulation, wide load availability, and manual/automatic shift. The series can bear instant overload and can work continuously for long time and equipped with over voltage protection, phase protection, phase-order protection and machine hitch automatic protection function. Its advantage contains small volume, light weight, convenient installment and use, reliable implementation, and so on.
