Product Introduction
TEDGZ TESGZ column voltage regulator is a dry induction voltage regulator. The three-phase column voltage regulator changes the contact position between the brush and the polished surface of the column winding to change the turns ratio of the primary and secondary windings, and finally achieves the purpose of regulation. The column electric voltage regulator is a large contact electric voltage regulator, which is a replacement product for the induction voltage regulator.
Product functions and features
The appearance, weight, volume, efficiency, waveform, operation, installation and maintenance are all better than the induction voltage regulator of the same power. It is suitable for industrial and mining power, hospitals, national defense, scientific research and other departments as a continuously adjustable test power supply. The waveform output is distortion-free and meets the power supply requirements of the IEC standard for electrical test. The output voltage is adjustable from 0 to 430V, and other voltages can be customized; its output voltage is smooth and stepless and can be adjusted under full load conditions. Reliable use, easy maintenance, strong overload capacity; it is an ideal voltage regulator equipment for on-site voltage regulation, power regulation, light regulation, and speed regulation.
