A voltage stabilizer is a type of  mains regulator which uses a continuously variable autotransformer to maintain an AC output that is as close to the standard or normal mains voltage as possible, under conditions of fluctuation.

It uses a servomechanism (or negative feedback) to control the position of the tap (or wiper) of the autotransformer, usually with a motor. An increase in the mains voltage causes the output to increase, which in turn causes the tap (or wiper) to move in the direction that reduces the output towards the nominal voltage.

Special Features:

1.Three-phase separate-adjustment compensating alternative stabilizers

2.Automatically maintain stability of output voltage when voltage fluctuates because of external power web voltage undulation or load change

3.Large volume, high efficiency, no waved distortion, stable voltage regulation, wide load availability and manual/automatic shift

4.Can bear instant overload

5.Can work continuously for long time and equipped with over-voltage, phase, phase-order and machine hitch automatic protection functions

6.Small volume, lightweight, convenient installment and use

7.Reliable implementation
