Product Overview
The SBW-F series three-phase automatic compensation power stabilizer is an optimized and improved version of the SBW series products. It is suitable for grid conditions where the three-phase input voltage imbalance exceeds 5%. When three-phase fluctuations or uneven load currents cause voltage differences between phases, the three-phase output can automatically balance the voltage while maintaining smooth voltage regulation. It is also very suitable for the design of ultra-high-power stabilizers above 1000 KVA, featuring large capacity, high efficiency, no waveform distortion, and stable voltage regulation. It is widely applicable to various loads, can withstand instantaneous overloads, operate continuously for long periods, supports manual/automatic switching, and includes overvoltage protection, phase loss, phase sequence protection, and automatic protection against mechanical faults.
