The series has been developed together as a single transformer solution for currents up to 40kA for aluminium welding and projection welding. This includes high rise time application and very short pulses.

High power at a minimum of weight are characterizing this series.

  • Operating frequency  1000-1200 Hz
  • Nominal power ranging from 121 to 377 kVA (at 50% duty cycle)
  • Secondary voltage of 6,4, 8,9, 13,2, 17. 21,4 V available
  • single tap design
  • M2 rectifier circuit
  • Optional with 2 or 4 diodes
