High-power high-voltage 40kW 150V to 450V 200A bi-directional air-cooled DC/DC converter RedPrime from Zekalabs

The DC/DC 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.

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.

Applications
