Features of MSS1000 Series Digital Intelligent Soft Starter


  1. starting method::①Voltage ramp start     ②Current limiting start     ③Jog

  2. No phase sequence requirement for input power

  3. All parameters are adjustable

  4. During the starting process, it has multiple protection functions: overcurrent, phase loss, start timeout, etc.

  5. Has a soft parking function

  6. Variable rated power control to match different specifications of the motor to ensure starting effect and accurate fault diagnosis

  7. Unique anti-"stolen stop" and "stealing" technology: CPU "running" will not terminate the operation of the motor

  8. True phase failure protection: no phase loss

  9. User parameters are stored in FLASH and never lost

  10. The panel display is intuitive and the human-machine interface is excellent

  11. True rms current sampling and display to ensure the accuracy of various control functions

  12. High reliability, high stability, high integration of hardware and software design, strong anti-electromagnetic interference.


Specification of MSS1000 Series Digital Intelligent Soft Starter

For MSS1000 series soft starter, three pairs of reverse parallel thyristors are connected in series to the stator circuit of motor. The input voltage of the motor will change with the thyristors conduction degree, which can be controlled by changing the triggering angel of the thyristors. So, the motor can be started more softly and smoothly. When the start process has completed and the equipment output voltage is up to the rated voltage, the bypass, three-phase contactor KM will close by the control of bypass output signal. At this time, the AC motor will put into operation in power grid, shown as Figure4-1.

When the bypass contactor is closed and the motor is in the state of bypass operation, the starter will turn off thyristor trigger pulse. If you have set the soft stop function, the soft starter will first open the thyristor, then disconnect the bypass contactor, and then gradually reduce the thyristor conduction angle, so that the motor slowly stops to achieve the purpose of soft-stop.
