Overview: DBW, SBW series compensation AC power regulator, is easy special introduction of foreign advanced technology, combined with the status quo of power, to stabilize the AC voltage and the development of energy-saving products. Regulators by the compensation circuit, voltage detection, servo motor control circuit gear transmission mechanism, electrical switches and operating circuits, current and voltage measurement and protection circuit. Wherein the compensation circuit, voltage detection, servo motor control and reduction transmission mechanism composed of the output voltage automatic compensation system, when the power distribution network voltage fluctuations or load changes can automatically maintain output voltage stability. This series combines the traditional electronic communication, induction and magnetic saturation regulator of type long, to overcome the small traditional regulator capacity, loss, waveform distortion and other shortcomings, with a large capacity, high efficiency, no waveform distortion, stable voltage regulation, and easy maintenance, operation and reliable. Can be widely used in computer industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, telecommunications, hotels, research and other departments, precision machine tools, computer tomography photography (CT), precision instruments, test equipment, lighting elevator imports equipment and production lines that require stable power supply place. Also applies to the power supply voltage is too low or too high, large fluctuations in the low voltage distribution network end users and large load fluctuation of electrical equipment, especially for all of the grid voltage waveform requires high power sites. Applications: industrial and mining enterprises, railways, research institutes, communication base stations, banking, securities, telecommunications, radio and television. Features: 1. Simple operation, with automatic and manual transmission functions. 2. The single power capacity of up to 2000KVA or more. 3. load adaptable, stable operation in a variety of complex conditions. 4. overvoltage, undervoltage, overcurrent, phase protection function, safe and reliable. 5. The output waveform is stable without distortion additional distortion is less than 1%. 6. smooth operation, load regulation and grid regulation can be less than 2%.
