SBW series three-phase high-power voltage regulator (50K-2000K)

The SBW three-phase compensation power stabilizer is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, causing the position of the voltage regulator carbon brush to change. By automatically adjusting the coil turn ratio, the output voltage is maintained stable

Product Features

  • 1、SBW regulators also improve the reliability of the power system. In operation, the power system may be disturbed by external factors,

          such as weather changes,equipment failures, etc., which will lead to fluctuations in the voltage of the power system

  • 2、The SBW regulator can play a role in improving the quality of the power supply. In the power grid,

          full of a variety of electrical equipment, they have different requirements for voltage

  • 3、SBW compensated regulators respond quickly. Whether it is a sudden load change or a grid failure,

          it can sense the voltage change in an instant and make adjustments quickly to maintain a stable output voltage

  • 4、SBW compensation regulator has high precision regulation function. Through precise electronic control,

          it can minimize voltage fluctuations and ensure the normal operation of various electrical equipment in the power system

  • 5、SBW compensation regulators have a wide range of adaptability. Whether it is a low-voltage rural power grid or a high-voltage industrial power system,

          it can meet different needs and provide stable power output for various users
