Product Introduction
SBW series intelligent digital AC voltage regulator stabilizer is designed for high power/capacity requirement with servo motor(alternator ). When the supply voltage of the distribution network fluctuates or the load changes, the voltage regulator will stabilize the output voltage automatically. It has high capacity, high efficiency, wide regulation range, fast response, no additional waveform occurred and other valuable features. The size is two-thirds than traditional machine, to help customer save space. Humanized design with LED digital indication, easy to operate.
