Device Description

The unit is a bidirectional 20kW / 500A, water-cooled isolated DC-DC power converter for on-board integration in a hybrid or EV applications.

Having numerous communication interfaces including RS485 (Modbus RTU) and CANBus, makes the integration with your control network an easy task.

Providing various modes of operation, programmable limitations and additional logic integration possibilities, it can fulfill various tasks and functions.

The device has a design with fully integrated control, power units and filter bank for minimizing the size and the weight of the installed components. It features an IP67 protection level.

Using the ZekaTrace™  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 application.
