Product Description

STG Single-phase high accuracy full automatic AC voltage stabilizers is made of regulator,servo motor,automatic control circuit and so in,When the voltage of the network is not steady or the load varies,the automatic sampling control circuit makes a signal to drive the servomotor to adjust the postion of the carbon brush of the regulator so as to have the output voltage regulated to the rating and to obtain the steady state.This machine has advantages of small volume,light weigh,undistorted waveform,high efficiency,reliabli performance,and time-delay,over-voltage,etc,the series of stabilizers driven,of general type,the indeel boltage stabilized sources which can be widely applied to any occasions requring power to assure the normal operation of yourpower driven equipment.
Computers ,test equipment,lighting systems,safety alarm systems,X-ray systems,communication systems,medical equipment,duplicators,stereo sound equipment,color film developing equipment.
