SVC (TND) Series single-phase high accuracy full automatic AC voltage stabilizers one series four main products, are such constructed they are composed of the contact type self-coupling voltage regulator, servo motor, automatic control circuit ,etc, 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 position of the carbon brush of the self-coupling voltage regulator so as to have the output voltage regulated to the rating and to obtain the steady state. Having the advantages such as wide varieties, complete specifications, beautiful appearance, etc. and the characteristics such as undistorted waveform, high efficiency, reliable performance, long-term operation, etc., and also being provided with the protective functions such as time-delay, over-voltage, etc., the series of stabilizers, of the general type, are the ideal voltage stabilized sources which can be widely applied to any occasions requiring power to assure the normal operation of your power driven equipment.
