    SBW Series Three-phase High-power Automatic Compensating Stabilized Voltage Supply


     

     

               

     

    ·Description

    SBW and SBW-F Series three-phase high-power automatic Compensating Stabilized Voltage supply are energy-saving types that were developed by our company, combining imported technologies and domestic status quo.. SBW is the tracking type power supply with its voltage regulation process of the voltage being adjusted by three sets of carbon brushes motivated by one motor. SBW-F is the split adjusting type power supply with its voltage regulation process being adjusted by three independent sets of carbon brushes motivated by three independent motors. When the external voltage fluctuates or the loads’ changes, it can automatically maintain a stable output voltage. This series have the advantages of traditional electronic communication type, induction type and magnetic saturation type regulator, and overcome the disadvantages of traditional regulator’s small capacity, big loss, and big waveform distortion. It has large capacity, high efficiency, no waveform distortion, stable voltage adjusment, convenient maintenance and high reliability.

    ·Application fields

    They are ideal for the computers, precision machine tools, computerized tomography (CT), precise instruments, elevator lighting, and experimental facilities in industrial and mining enterprises, construction, education, health care, scientific research, railway, transport, oil industry, post and telecommunications and hotels.

    ·Features

    ■Random switching of main power voltage regulation;
    ■High precision voltage regulation, no output waveform distortion;
    ■The intelligent automatic power distribution guarantees the unattended watching (optional);
    ■Compatible with any loads (resistive, condensive, and inductive) for long and continuous use;
    ■Overload protection, short circuit protection, output over voltage protection, short phase and wrong phase automatic protection;
    ■Non-segmented voltage adjustment, voltage lifts in linearity mode, and output voltage is continuous and adjustable;
    ■Wide voltage regulation range, precise adjustment, big capacity, high efficiency and non-additional distortion of the output waveform, compatible with all kinds of loads;
    ■The regulator consists of the compensating circuit, voltage testing circuit, servomotor control circuit, decelerate transmission, protection circuit and other circuits;

    ■The direct mode and voltage mode are switchable; the direct mode connects the state grid with the loads directly for periodical maintenance without interrupting the loads;
