ABOUT EVADA STB AUTOMATIC VOLTAGE STABILIZER
The EVADA STB automatic voltage stabilizer consists of contact voltage regulator, sampling control circuit and servomotors as well. It has excellent features, such as small waveform distortion, high efficiency, high power factor, free from the effect or frequency variation of supply. It can be widely used in most situations where the voltage stabilization is required.
