SBW series three-phase automatic compensation power regulator is designed by our factory to stabilize AC voltage by introducing and absorbing foreign technology in combination with our country's power grid conditions. When the voltage fluctuation caused by voltage fluctuations or load changes in the external power supply network, it can automatically maintain the stability of the output voltage. SBW series voltage regulator series products have the advantages of large capacity, high efficiency, no waveform distortion, stable voltage regulation compared with other types of voltage regulators, SBW high-power regulator is suitable for a wide range of loads, can withstand instantaneous overload, SBW high-power regulator can work continuously for a long time, manual/automatic switching at will, SBW high-power regulator is equipped with overvoltage protection, phase loss, phase sequence protection and automatic protection of mechanical faults, as well as small size, light weight, easy to use and install, reliable operation and other advantages. SBW high-power voltage regulator can be widely used in large-scale mechanical and electrical equipment, metal processing equipment, production lines, construction engineering equipment, elevators, medical equipment, embroidery and textile equipment, air conditioning, radio and television, household appliances, lighting and other places that need voltage regulation in industry, agriculture, transportation, post and telecommunications, military, railway, scientific research and culture, etc. SBW series regulators should be used indoors, and the normal use conditions of SBW regulators are: 1. Ambient temperature: -10°C-45°C 2. Altitude: <1000M 3. Relative humidity: 20%-90% 4. There are no gases, steam, chemical deposits, dust, dirt and other explosive and corrosive media that seriously affect the insulation of the regulator. 5. There is no serious vibration or bump in the installation site of SBW series regulators.
