Product Overview
The SBW and DBW series AC voltage regulators (hereinafter referred to as regulators) are a self-developed and designed power supply product by our company, tailored to the current situation of China's national power grid. They can automatically maintain stable output voltage when fluctuations in the external power supply network or load changes cause voltage fluctuations. Compared to other types of regulators, this series boasts advantages such as large capacity, high efficiency, no waveform distortion, and smooth voltage regulation. It is suitable for a wide range of loads, can withstand transient overloads, and can operate continuously for long periods. The regulators feature manual/automatic switching, overvoltage protection, phase loss protection, phase sequence protection, and automatic mechanical fault protection. The machine is known for its reliable operation, compact size, lightweight, and easy installation and use.
