DC/DC- & DC/AC-Converters

bidirektionales Wandlermodul

General facts

Converter modules are used for to connect several sources, sinks and memory items of electric energy with different operating voltage ranges from 12V DC to 350V DC or 230V AC through a DC intermediate circuit. They provide high efficency, flexible control as well as a digital interface. A simple connection to a 230V AC network with a inverter module is possible, because of an intermediate circuit voltage of 380V DC.


Principle of a bidirectional energy flow



DC-Bus – side of the module which can be connected with other DC/DC modules or any other 380V DC electric component (e.g. inverter)
variable voltage – side of the module on which the components were connected.


Features shared by all modules

  • Compact construction
  • Bidirectional power flow
  • Active air cooling (temperature controlled)
  • Serial interface (electrically separated) via RS232 interface adapter (manual)
  • Data exchange through ASCII protocol
