Zekalabs SiC

The unit is a bidirectional 120kW / 850V wall or cabinet mountable highly efficient and compact SiC DC/DC power converter. 

As a combined buck/boost air-cooled converter, it can be set up in either charging or discharging mode. Moreover, the units can be stacked for achieving higher power with no communication between them (optional).

Providing various modes of operation, programmable limitations and additional logic integration possibilities, it can easily turn into the heart of your energy conversion system.

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

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 a Zekalabs Communication Bridge (optional).

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.

Using the ZekaTrace™ and ZekaStream™ technology (optional, ordered separately), 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 converter in your design is enough to change the way you commission the whole power plant.

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.
