    BRIEF INTRODUCTION
    ZBW series static automatic AC voltage regulator stabilizer is designed with compensating transformer of high primary to secondary ratio for voltage correction of ± 20%. Direct AC-AC converter circuit and SCR module controlled to improve the overall system response with fast voltage correction. PWM control operation using high end DSP controller to achieve correction time of 1 to 1.5 cycle. Excellent performance in voltage sensitive application. When the supply voltage of the distribution power grid fluctuates or the load changes, the voltage regulator will stabilize the output voltage automatically. The size is two-thirds of traditional machine, to help customer save space. Humanized design with LCD digital indication, easy to operate.
