The SBW series compensating voltage regulator designed for stable AC voltage is developed by our company by introducing and absorbing the most advanced technology from western Europe and combining with China's national conditions. When the external power supply network voltage fluctuation or load fluctuation causes the voltage fluctuation, the device automatically maintains the output voltage stability.
This series product compared with other type voltage regulator has a large capacity, high efficiency with no waveform distortion. It provides stable voltage regulation and is widely used for most loads. It can work continously for long term by either manual control or automatic control between which can be smoothly switched. It provides protection for over voltage, over current and mechanical fault automatic protection device. Also the device has small volume, light weight with convenient installation and reliable operation etc.
The device is widely used in industry, agriculture, transportation, post and telecommunications, military, railway, research culture in the areas of large mechanical and electrical equipment, metal processing equipment, production lines, construction equipment, elevators, medical equipment, computer rooms, cumputer control equipment, embroidery, textile equipment, air conditioning, radio and television, hotel and household appliance lighting and so on where those need to be regulated.
