The SBW and DBW series AC compensated voltage regulators (hereinafter referred to as voltage regulators) are power supply products independently researched and developed by our company in response to the current situation of China's national power grid. They can automatically maintain a stable output voltage when external power supply network voltage fluctuations or load changes cause voltage variations. Compared with other types of voltage regulators, this series of products has the advantages of large capacity, high efficiency, no waveform distortion, and stable voltage regulation. They are suitable for a wide range of loads, can withstand instantaneous overload, can work continuously for long periods, support manual/automatic switching, and are equipped with overvoltage protection, phase loss, phase sequence protection, and automatic mechanical fault protection. The machines are reliable in operation, compact in size, lightweight, and convenient to use and install. This series of products has passed the European Union 'CE' certification and obtained authoritative testing from the Shanghai Testing Center certification authority, and can be used interchangeably with foreign products.
