Isolated 30kW 260V AC/DC converter battery charger with CAN control by Zekalabs

The unit is an air-cooled, isolated 30kW/250V AC-DC three-phase uni- or bi-directional converter 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 and functions.

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.


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:

  • EV Level 3 DC fast charging stations and infrastructure
  • electric and hybrid vehicles charging and discharging
  • micro-grids infrastructure
  • energy storage infrastructure
  • battery / fuel-cells / supercaps charging and discharging
  • hybrid/electrical propulsion support infrastructure
  • power supply for servo drives and applications
