Description
By making the integrated circuit control several thyristor voltage zero-crossing on and off in a specific order to change the size and polarity of the compensation voltage, it is a perfect combination of thyristor AC switch technology and transformer technology. Using high-power thyristors (silicon controlled rectifiers) instead of machinery and carbon brushes to control voltage regulation, the capacity can reach 3000KVA, the maximum compensation range can reach ±50%, and the efficiency can reach more than 99%. It is leading the development direction of high-power power regulated power supplies. energy-saving green environmental protection products. Equipped with all power protection functions, it realizes non-contact voltage regulation; it is non-polluting, and can maintain good performance under various harsh power grids and complex loads for more than 100,000 hours of continuous trouble-free operation, realizing long-term maintenance-free. It has the advantages of super high efficiency, super long service life, super stability and adaptability.
