Products Description

The SBW series three-phase fully automatic compensated power voltage regulator is suitable for applications where voltage
fluctuations are caused by variations in the external power grid voltage or load changes. It automatically maintains a stable output voltage. Compared with other types of voltage regulators, this series offers advantages such as large capacity, high efficiency, no waveform distortion, and smooth voltage regulation. It is suitable for a wide range of loads, can with stand instantaneous overload, and can operate continuously for long periods. It supports manual/automatic switching and is equipped with overvoltage protection, phase loss protection, phase sequence protection, and automatic protection against mechanical failures. In addition, the unit features a compact size, light weight, easy installation, and reliable operation.
