    UNT-HVSS-BZ-D-1050

     Medium Voltage Softstarter for one AC motor: Rate power of AC motor:       9500 kW;Rate voltage:                        6 kV;Rate current:                       1050 A;Dimensions:              1000x1500x2300mm;Weight:                               - kg.Incoterms: FOB Xingang Specification● The embedded high reliability & real time motor protection function can monitor the motor’s working conditions when it starts or under the normal operation.  ● Applying the touch screen interface, the operation is much more convenient and comfortable, there is component structure inside the equipment and modular installation is available, the equipment has multiple overvoltage absorption and protection function. The equipment can decrease the harmful impact on grid when motor gets start by limiting and clipping of instantaneous dv/dt, lightning impulse voltage, switching overvoltage and transient transition progress.  ● The device has the mode of multiple optional soft start and soft stop, applies to no-load, full load, and 150% overload starting. Jumping mode can realize the smooth start under bigger over-load, which can save the investment cost and prolong the lifetime of the motors and have a good performance on energy saving.
