Product Description Application SVC fully automatic Servo voltage stabilizer consists of contact voltage regulator, sampling control circuit and servo motor. When input voltage or load changes, sampling control circuit will sample and amplify the voltage, and the servo motor will rotate in the desired direction, which turns the arm, adjusting voltage until the output voltage is regulated into the rated output voltage. The product is of small size, light weight, less output waveform distortion and reliable performance. To guarantee its quality, foreign advanced technology and main parts are introduced and imported. It is widely used in electrical appliances which need constant voltage power supply, and in fields of industry producing, scientific research and medical hygiene. The product itself consumes little and can be continuously used for a long time.
