Isolated 5kW 80V 70A AC/DC converter battery charger with CAN control from Zekalabs

The unit is an air-cooled, isolated AC/DC converter / battery charger with multiple applications for on-board integration in a hybrid or EV infrastructure.

Having totally autonomous functionality or optional control interfaces including RS485 and CAN and utilizing MODBUS, makes the integration with your control network an easy task. Flexibility and control are the key features of the unit.

Having a design with fully integrated control, power units, filter bank, precharge and contactors balances the size and the weight of the installed components.

Using the ZekaTrace™ technology (optional), 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 programmable setting and limitations thus allowing easy integration for the following applications:

  • fork-lifts
  • cranes
  • electric vehicles
  • electric and hybrid vehicles
  • on-board power converter in electric/hybrid vehicles
  • on-board battery/supercaps charger in electric/hybrid vehicles
  • hybrid/electrical propulsion and traction
  • battery / fuel-cells / supercaps charging and discharging
