            SBW High Rated Compensation Stabilizer

            SBW series intelligent high power compensation three-phase AC voltage stabilizer is designed by microcomputer control to stabilize AC voltage. When the external power supply network voltage fluctuation or load fluctuation causes voltage fluctuation, it can automatically adjust and maintain the output voltage stability.?This series of voltage stabilizers are widely used in industrial and mining enterprises, oil fields, railway hospitals, post and telecommunications, hotels, construction, scientific research and other departments of mechanical and electrical equipment, production of automatic assembly lines, test equipment, elevators, medical equipment, computer room, central air conditioning, cranes, mixers and many more.

            The display window

            In the running state, the upper display window is a voltage display window, and the input voltages Va, Vb, Vc, Vab,?Vbc, Vca and the

            output voltages Va, Vb, Vc, Vab, Vbc, Vca are displayed, and are switched by the voltage switching?key. The voltage displayed by the

            primary voltage switching button is switched once at Va, Vb, Vc, Vab, Vbc, and?Vca, and the voltage displayed after the voltage switching

            button is continuously connected for 3 seconds is switched?between the input voltage and the output voltage. The lower display window

            Product features


            The SBW series is a three-phase regulated regulator. The voltages of the three phases A, B and C are synchronously?adjusted by a

            servo?motor, and the sampling voltage is the average value of the three-phase voltages of the?regulators A, B and C.


            The SBW-F series is a three-phase split regulator. The voltages of each phase of A, B and C are independently?adjusted by a servo

            motor, so there are three independent servo drive mechanisms, and the sampling voltage is the?phase voltage of each phase of the

            output of the regulator. This model is suitable for grid or load imbalance situations?where the input voltage is extremely unbalanced

            or for precision equipment.


            Note 1: Dimensions, weights, etc. are for reference only and are subject to change without notice.

            Note 2: All the above products have bypass and no self-start.

            Note 3: If the customer has self-starting requirements, please contact the manufacturer.

            The relative graph of current and input voltage


            Inverse time overcurrent protection characteristic, the relationship between output current and protection hysteresis time:


            The relative graph of current and protection delay time.


            T is the protection delay time, Iout is the output current, and Ig is the current overcurrent protection value.

            Fault inquiry

            In the running state, press the increase button and decrease button for more than 3 seconds to enter the fault query.?The fault code

            is: 0 means no fault, 1 means overvoltage and "overvoltage" display, 2 means undervoltage and?"undervoltage" display, 3 means

            overcurrent and "overcurrent" display. 5 indicates the phase sequence simultaneous?"phase sequence" display. 6 indicates the absence

            of the same "phase loss" display. After entering the fault query, the?above display window displays b1, indicating the most recent fault.

            The following display window displays the most?recent code, and the protection display window displays the most recent fault type.?After

            pressing the setting button?again, the above display window displays b2, the lower display window shows the code of the last?previous

            fault,?and?the protection display window shows the last previous fault type. After pressing the setting button again, the voltage?display

            window displays b3. The lower display window displays the code of the last two previous faults. The protection?display window?displays

            the last two previous fault types. Press the Set button again to enter the running state.
