Introduction:
DBW/SBW series full automatic compensated regulator is designeg and developed with the international advanced compensation technology. It can keep the output voltage in steady state automatically when the network voltage fluctuated or the load current varied, which can ensure the consumer run smoothly. It has the advantage of large capacity, high effficiency, no waveform distortion, simple operation and full-capacity output under tower input voage if compared with other voltage stabilizer. The voltage regulator provided with over-voltage, over-current, phase sequence etc protection function.
Features of SBW Automatic Voltage Regulator (AVR)
1. The AC voltage regulator is equipped with bypass system
2. Compensated voltage technology is adopted
3. Wide input voltage range
4. Over voltage protection
5. The voltage regulator has output voltage three phase auto-balance function
6. SBW voltage regulators are widely used in electric power supply systems.
