This highly efficient and compact SiC power converter is a bidirectional cabinet mountable unit with many different applications. Moreover, the converter can be stacked for achieving higher power with no communication between them. The rated current overload capacity allows the converter to be used in highly dynamic applications.

Having numerous communication interfaces including Ethernet, RS485 and CANBus and utilizing MODBUS, makes the integration with your industrial network an easy task. PROFIBUS interface is also available using the MODBUS-to-PROFIBUS Gateway. The integrated MODBUS master allows different MODBUS slaves to be attached to extend IO and functionality.

Several digital and analog inputs and outputs are available for additional programming and logic allowing extra flexibility during the system design or an ongoing project.

Powered by ZekaTrace™ and ZekaStream™ technology you will be able to display the electrical characteristics and diagnose the health of the system with an unprecedented resolution for the industry. Only one such device in your design is enough to change the way you commission the whole power plant.

Having a design with fully integrated control, power units and filter bank balances the size and the weight of the installed components. Mounting and servicing of these usually heavy components within the cabinet becomes a much more comprehensive task.

Silicon Carbide

Based on Silicon Carbide, the converter provides high efficiency of around 99%. Its ultra compact design extremely reduces the size and the weight of the installed components.


This versatile, multi-application device provides various modes of operation, programmable limitations and additional logic integration possibilities and it can easily be used into the following applications:

  • energy storage    
  • battery / supercaps charging and discharging   
  • load balancing and peak shaving    
  • hybrid/electrical propulsion    
  • micro-grid
