伺服电机稳压器，大功率SBW、DBW系列单、三相全自动补偿式电力稳压器是适用于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稳定。本系列产品与其他型式的稳压器相比， 具有容量大、效率高、无波形畸变、电力调节平稳等优点，适用负载广泛，能承受瞬时超载， 可长期工作，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，本机体 积小，重量轻、使用安装方便，运行可靠等优点。
DBW/SBW Series single、three phases full automatic compensated power voltage stabilizer appliant to when the power network voltage fluctuates or the load current varies, it can keep output voltage in steady state automatically, Compared with other voltage stabilizers, it has the advantage of large capacity, high efficiency, no wave distortion, stable voltage adjustment, suitability for kinds of loads, bearing instantaneous overload, working continually for long time, as well as free transferring between manual controland automatic control, etc, besides, it is provided with protection against over-voltage over current ,phase failure and protection for phase sequence and has following merits: small volume, light weight, convenient installation and reliable running and so on.
使用场合
广泛用于邮电、商场、电梯、医院、学校、印刷、纺织、证劵等所有需要的正常电压保证的场合 及大、中型工矿企业车间，部分供电及重要设备和配套。
Widely used in post and telecommunications, department stores, elevators, hospitals, schools, printing, securities and other occasions where all needs normal voltage to ensure, such as workshop mines medium enterprises, some of the important equipment and computerpower and support.
