Product Description


DBW, SBW series single and three-phase full-automatic compensation is a power stabilizer, which is designed to stabilize AC voltage by introducing advanced technology from Western Europe. When the external power supply network voltage fluctuates or the load changes cause voltage fluctuations, it can automatically maintain the stability of the output voltage.


Compared with other series of voltage regulators, this series of products has the advantages of large capacity, high efficiency, no waveform distortion, and stable voltage adjustment. It is suitable for a wide range of loads, can withstand instantaneous overload, and can work continuously for a long time. Manual and automatic switching. It has the advantages of overvoltage protection, phase loss, phase sequence protection and mechanical failure automatic protection, as well as small size, light weight, easy use and installation, and reliable operation.


Widely used in post and telecommunications, shopping malls, elevators, hospitals, schools, printing, securities and other occasions that require normal voltage, large and medium-sized industrial and mining enterprise workshops, part of the power supply and important equipment and stand-alone supporting.
