SBW/DBW series three phase and single phase fully automatic compensationpower stabilizers are suitable for automatically maintaining output voltage stability when voltage fluctuations are caused by external power supply network voltage fluctuations or load changes. Compared with other types of voltage regulators, this series of products has the advantages of large capacity, high efficiency, no waveform distortion, and stable voltage regulation. It is suitable for a wide range of loads, can withstand instantaneous overload, can work continuously for a long time, and can be manually/automatically switched. It is equipped with overvoltage protection, phase loss, phase sequence protection, and mechanical fault automatic protection. This machine has the advantages of small size, light weight, convenient installation, and easy reliable operation.
SBW/DBW series compensationpower stabilizers are widely used in post and telecommunications, shopping malls, elevators, hospitals, schools, printing, textiles, securities and other occasions that require normal voltage guarantee, as well as in workshops of large and medium-sized industrial and mining enterprises, some power supply and important equipment and supporting facilities.
