SBW and DBW series compensatory AC power regulator (hereinafter referred to as voltage regulator) is introduced by our factory, absorbing advanced 

technology at home and abroad, at the same time, combined with China's national conditions, designed to stabilize the AC voltage, when the external

 power supply network voltage fluctuation or load changes cause the power grid fluctuation can automatically maintain the fluctuation of the output voltage.

       This series of products compared with other forms of voltage regulator has large capacity, high efficiency, smooth waveform distortion, voltage regulation, 

wide load, can withstand instantaneous overload can work continuously for a long time, manual, automatic switch, and with overvoltage, undervoltage, 

overcurrent, phase sequence protection, mechanical fault automatic protection device, small size, light weight, convenient installation, reliable operation

 and other characteristics. Can be widely used in industry, agriculture, transportation, post and telecommunications, military, railway, scientific research and

 culture and other fields of large mechanical and electrical equipment, metal processing equipment, elevator, medical equipment, computer room, computer

 control equipment, embroidery textile equipment, air conditioning radio and television and household appliances lighting and other places that need to stabilize pressure.

        It consists of three-phase compensation transformer, three-phase contact voltage regulator, transmission mechanism, brush contact system, box body and electrical

 control system. The outer surface of the column winding of the three-phase contact regulator is polished to remove the smooth conductor; the transmission mechanism

 is composed of motor, worm wheel, worm, sprocket and chain; the brush system structure is reasonable and reliable to ensure the brush pressure; small size, good heat 

dissipation, striking detection instrument position and accurate indication.
