Detailed Product Description

avr ( automatic voltage regulator, alternative current voltage regulator )

The design of compensating AC stabilizer has introduced western advanced techniques and combined with national condition to regularize AC voltage. When voltage fluctuates because of external power web voltage undulation or load change, the series can automatically maintain stability of output voltage. Compare with other style of stabilizer, the series feature large volume, high efficiency, no waved distortion, stable voltage regulation, wide load availability, and manual/automatic shift. The series can bear instant overload and can work continuously for long time and equipped with over voltage protection, phase protection, phase-order protection and machine hitch automatic protection function. Its advantage contains small volume, light weight, convenient installment and use, reliable implementation, and so on.
This series can be used as high quality alternative voltage stabilizer supply for industry, agriculture, transportation, military, postal office, railway, scientific, research institutes, precision machine tools, industrial production line, medical facilities, architectural engineering equipment and testing equipment, air condition, broadcast and TV stations and hotels.
