Origin China Model Number SVC Current Type AC Phase Single Phase Usage SVC SVC fully automatic voltage stabilizer, sampling control circuit and servomotor as well. It has excellent features, such as small waveform distortion, high efficiency, high power factor, free from the effort of frequency variation of supply. It can be widely used in most situations where the voltage stabilization is required. Input voltage: 160V--250V, 70--130VOutput voltage: 220+/-3% with 110V+/-3%Phase: single phaseFrequency 50Hz/60HzResponse time with 1 sec, against 10% input voltage deviation Efficiency Better than 90%Relative humidity less than 95%Waveform distortion Non-lack fidelity in waveform.
