AMKASUN KU system has the following main advantages at a glance:

  • Very compact components which lead to small control cabinet space;
  • The entire system can be easy integrated directly as a part of the machine, meaning more cost savings;
  • Using AMK’s real-time synchronization with other systems it’s easy to create complex designs;
  • Can use integrated PLC to simple implement complex Motion Control functions;
  • Easy accessible and complex logging functions permit easy diagnostic features.


The AMKASUN KU family includes a large variety of units, with various features, including:

  • Output power : 0,5 – 60kVA;
  • Input voltages:
  • 230V single phase;
  • 230V 3-phase;
  • 380…480V 3-phase.
  • Optional can be used for line regenerative braking;
  • Can be equipped with various encoder technologies:
  • standard feedback inputs for resolver;
  • square-wave encoder;
  • sine-wave encoder.
  • Pulse transmission;
  • Optional PLC functionality;
  • Different busses available for interconnection with other units:
  • CAN;
  • Ethernet;
  • Profibus.


Standard functions available for the AMKASYN KU family:

Our laboratory offer free diagnosis for all types of electronic boards. We consider that unless we have identified the root cause of the malfunction we cannot estimate the appropriate repair cost. Usually, repairing costs do not exceed 30% of the price for a new motherboard or equipment.



Our service department ensures complex repairing processes for electronic components. The tasks are professionally administered and executed by well-trained engineers who can perform correct diagnosis and repairing from simple boards to multi-layer PCB (Printed Circuit Boards).


The repairing procedure includes:

  • in-depth cleaning of boards
  • rebuilding damaged circuits
  • building work schemes partly or fully, if necessary
  • circuit analysis in order to uncover flaws
  • replacing damaged components
  • preventive replacement for components that could cause further damage
  • software/firmware/bios backup
  • delivery towards testing area


Components inventory

The components are being replaced with spare parts belonging to our inventories, but there are cases when it is necessary to import several spare parts directly from the manufacturer/distributor. Our past experience has given us the possibility to build up good communication means with European, Asian and American manufacturers; therefore we also give you the benefit that, in accordance with our contract, we can cover any need of component required by the repair process.


Optional services

On demand, we also provide the following services:

  •  Delivering the equipment from/to your address
  •  Transportation can be made possible by using any of the following companies: DHL, UPS.
