4. General:

SBW-F series three phase split-adjustable full automatic compensated power voltage regulator, this products is three sets of single phase voltage stabilizer composed, and base on SBW series products improvement of voltage stabilizer, applicant to when input three phase voltage unbalance or power network fluctuation and unbalance load current fluctuation, It can keep output voltage in steady state automatically when the power network fluctuates or the load current varies. Compared with other voltage stabilizers, it has the advantage of large capacity, high efficiency, no wave distortion, stable voltage adjustment, suitability for kinds of loads, bearing instantaneous overload, working continually for long time, as well as free transferring between manual control and automatic control etc., besides, it is provided with protection against over-voltage, over current, phase failure/ phase sequence, delay and error protection etc, and has following merits: small volume, light weight, convenient installation and relit is reliable running and so on.

 

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:
