SBW-50KVA series intelligent AC voltage regulator is suitable for when the external power supply network voltage fluctuations or load changes caused by voltage fluctuations, can automatically maintain the output voltage stability. Compared with other types of voltage regulators, this series of products has the advantages of large capacity, high efficiency, no waveform distortion, stable voltage regulation, etc., suitable for a wide range of loads, can withstand instantaneous overload, can work continuously for a long time, manual/automatic switching, with overvoltage protection, lack of phase, phase sequence protection and automatic protection of mechanical failure, the machine is small in size, light in weight, easy to use and install. Reliable operation and other advantages. (Two types of score display and instrument indication). It is widely used in posts and telecommunications, shopping malls, elevators, hospitals, schools, printing, textile, securities and other occasions that require normal voltage assurance and workshops of large and medium-sized industrial and mining enterprises, some power supply and important equipment and supporting facilities.
