Overview
The SBW series single and three-phase fully automatic compensation power stabilizer is 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 widely applicable to loads, can withstand instantaneous overload, can work continuously for a long time, manual/automatic switching, and is equipped with overvoltage protection, phase loss, phase sequence protection, and mechanical fault automatic protection. The machine has the advantages of small size, light weight, easy installation, and reliable operation. (There are two types: score display and instrument indication).
Occasions for use
Widely used in all occasions that require normal voltage guarantee, such as postal and telecommunications, shopping malls, elevators, hospitals, schools, printing, textiles, securities, and workshops of large and medium-sized industrial and mining enterprises, as well as some power supply and important equipment and supporting facilities.
