4. General:
TNS series 3Phase Servo motor type Voltage Regulator adopts linear integrated circuit to form the control system, drive the contact voltage regulator to regulate automatically by controlling the servo motor, it is provided with delay, over-voltage, under voltage and over-current protection function which ensure the voltage stabilizer can supply safely; It has the advantage of high efficiency, low power consumption, high accuracy of stabilization, reliable and continuous work etc., and good for in regions where the net voltage is much fluctuating!
5. Work principle:
The voltage stabilizer is compensated of compensation circuit, voltage testing circuit, servo motor and gearing-down drive mechanism, main circuit, switching circuit, current and voltage measurement and protective circuit. The compensation circuit is composed of contact voltage stabilizer ad compensation transformer. The contact voltage stabilizer is connected in Y and put in the output terminal of voltage stabilizer, and the electric brush is connected to the primary coil of compensation transformer, and the secondary coil is series connected in main circuit, if the voltage fluctuation exceeds the precision range of output voltage, the voltage detection circuit will send signal to make the servo motor rotate forward or backward, and the servo motor enable the gearing-down drive mechanism to make the brush on the contact voltage stabilizer to slide, so as to change the compensation voltage of compensation transformer and realize the stability of output voltage. See its Electric Schematic Diagram as below,
6. Product workmanship:
With high mechanization equipments, the products will be more beautiful, compact and good heat dissipation. The automatic production process will be more efficient, lower labor cost, and increase production capacity, further to improve the overall performance of our products and production workmanship level.
7. After-sale services:
CONPO manufacturer guarantees free maintenance(except unsuitable operation) within one year after the date of Bill of Lading(B/L). After guarantee period, we provide free technical service and collect charges for damaged material, please contact our service department for any special condition.
8. Notes for ordering:
Please notify the model product, capacity, input voltage range and output voltage, accuracy as well as the application environment(normal product if no special requirements) when ordering.
