Green core Inductive Systems is developed for reactors in grid feeding and back dining converters.

It is useful for single-phase as well as three-phaseapplications and can also be used for many several reactor and transformer-topologies and applications like:

Power electronics, intelligent drive technology, power quality

!NEW! With potential-free watercooling-system !NEW!Green core - the energy saver in Power Quality: effective for regenerative inverters

  • High power efficiency
  • Switching frequency up to 20 kHz
  • Reduced design size and weightiness
  • Low noise emission
  • Manufactured in according to the
