AMVS Series Medium Voltage Soft Starter
 

AMVS  is  the computerized digital soft starter  for  MV AC motor ,  with Chinese display. Its system uses the advanced single chip microcomputer, PLC controller and color touch screen HMI and high voltage power electronic semiconductor devices and modern control technology to integrate a  new type of product  of  solid  state starter and running protection of MV AC motor. In addition to the excellent starting function, this product also has a perfect comprehensive protection function of the motor running, can ensure that the motor and mechanical transmission equipment  running in a safe and reliable operation of the various circumstances. Compared with other types of medium voltage motor soft starter (such as water resistance type), the soft starter consumes less energy in the process of starting , therefore it has the obvious energy saving effect, and itcan be used in the occasion of frequent starting. At the same time,  since the soft starter is made of solid state devices, it has the long-term use of free maintenance,  and a small equipment size, easy to move and a better vibration resistance as clear advantages. Further more, it has the following unique features and obvious advantages, becoming the  ideal replacement of   other traditional medium voltage soft starter.

Product Feature

1, Starting of initial voltage can be set according to the actual situation  and need flexibly, as low as to 15% of the supply voltage, and the highest could be  90%, make the motor have a larger starting torque and small starting current, reducing the equipment operation requirement for power grid capacity, saving the investment of equipment. Reduce the impact stress  to the motor and to the  mechanical transimission part  itself, and can prolong the service life of motor and transmission machinery.

2, When starting, the initial start voltage, the start time and starting current limit and so on, are available on color LCD touch screen to be easily set up and  be implemented, and soft stop deceleration time can be set freely according to the requirements of the load characteristics, to fully satisfy all kinds starting, slowing down and stop  condition of equipment and motor.

3, variety of starting mode ( reduced voltage starting ,constant current starting) control  to meet the various starting performance requirements of the device.

4, Perfect motor running protection function, can ensure the safety of the equipment operation, protection function are like:

 
     a.  protection alarm for input supply voltage high.

     b.  protection alarm for input supply voltage low.

     c.  the input power phase loss alarm.

     d. motor overload alarm for inverse time over current protection .
         medium voltage motor imbalanced current alarm

     f.  motor start excess time  protection alarm.

     g. the bypass contactor fault alarm.

     h. residual current leakage alarm  for the equipment.

     i.the main three-phase thyristor power device breakdown    damage  alarm and display.
 

     j.short circuit instantaneous tripping  alarm (which can be classified    as current transformer range 0.1- 2.5 times current).

5, The soft starter shows motor three-phase working  current and the residual current leakage, and the voltage of power supply, and displays the total motor running time, which is not affected by power outages, to facilitate the understanding of the equipment running total time, easy to carry out regular  maintenance.

 6,The running parameters of display are colored Chinese touch screen man-machine interface, easy  parameters setting is very intuitive. 
According to user requirements it can privide profibus dp communication interface, and remote monitor computer networking communication at the next higher level and to realize the remote control. (please notify when ordering  for other communication  need)

7, According to user requirements it can privide profibus dp communication interface, and remote monitor computer networking communication at the next higher level and to realize the remote control. (please notify when ordering  for other communication need)
