General (DBW.SBW series single-phase and three-phase full-automatic compensated voltage stabilizer)

    DBW . SBW series single - phase and three - phase full - automatic compensated voltage stabilizer (hereinafter referred to as voltage stabilizer ) is designed for stabilizing AC voltage and made with Western Europe advanced technology and on the basis of our country national conditions . It can keep output voltage in steady state automatically when the power network voltage fluctuates or the oad 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 and protection for phase sequence and has following merits: small volume, light weight, convenient installation and reliable running and so on.

Application  (DBW.SBW series single-phase and three-phase full-automatic compensated voltage stabilizer)

   It can be applied to large type electromechanical equipment, metal processing equipment, production line , construction device , elevator , medical equipment, equipment of light and textile industry, air-condition, TV set, household appliance and lighting used for industry, agriculture, traffic, military, railroad, scientific culture, etc, where need voltage stabilization.

¡ñThe product is used indoors, the normal service conditions for it as follows:
