SVC(TNS) Series three phase high precision automatic voltage stabilizer


TNS series is one kind of our competitive products; consist of contact auto voltage regulator, servo motor, automatic control circuit and etc. When the voltage fluctuates or the load varies, automatic sampling control circuit will send signal to drive  the servo motor which can adjust the position of carbon brush of auto voltage regulator, then the output voltage will be adjusted to rated value and get a steady state.

This Servo Controlled Voltage Stabilizer (TNS series) is general type, which has  the function of connecting via the commercial power. Compared with other voltage stabilizers, it has the advantage of great variety, complete specification, nice appearance and obvious features of high efficiency, no wave distortion, reliable performance, working continually for long time. Moreover, TNS series is provided with short time delay and over voltage protection, the long time delay and under voltage protection also can be set according to user requirement. This product is an ideal stabilized voltage supply, widely used in any locations requiring electricity and ensures your power device can run normally.


The power supply of the electric equipments and facilities in housing、factory、school、shop office precision instrument for scientific experiment,also is suitable for test instrument、communication system、industrial equipment、medical equipment and so on.
