SBW-30KVA 30kW Three Phase Voltage Stabilizer
AC voltage stabilizer is developed by our company according to the load characteristics and designed for stable AC voltage. When the external power supply network voltage fluctuates or the load changes cause voltage fluctuations, and output voltage is automatically kept stable. This special voltage stabilizer has the characteristics of large capacity, high efficiency, small waveform distortion, stable voltage adjustment, etc., and it is suitable for a wide range of loads, can withstand instant overload, can work continuously for a long time, and can be switched by manual and automatic control. It has automatic protection devices for overvoltage and over current, easy to use and install, and reliable in operation.
