SBW High Power Three-Phase Compensatory Voltage Regulator
■ Product overview
SBW series three-phase fully automatic compensation type power regulator is designed by our company to stabilize AC voltage by introducing and absorbing advanced technology from Western Europe and combining with China's national conditions. When the external power supply network voltage fluctuations or load changes caused by voltage fluctuations, can automatically maintain the stability of the output voltage.
■ product features
Compared with other types of voltage regulators, this series of products have 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, can work continuously for a long time, manual/automatic switching, and is equipped with Overvoltage protection, phase loss, phase sequence protection and automatic protection of mechanical faults. This machine has the advantages of small size, light weight, convenient use and installation, and reliable operation. (divided into digital display and instrument indication)
■ Scope of Use
This series of voltage stabilizers have been widely used in electronic computers, precision machine tools, precision instruments, experimental devices, elevators and production lines in industrial and mining enterprises, printing, machine tools, post and telecommunications, railways, construction sites, schools, hospitals, hotels, national defense, scientific research and other departments.
