Device Description

The unit is an air-cooled, isolated 25kW/800V AC-DC three-phase uni- or bi-directional inverter for many different 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 fulfil various tasks 


Having a design with fully integrated control, power units, filter bank, precharge, contactors and EMC filters 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.

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.
