C CORES

UMNCC-cores are manufactured with nanocrystalline iron based amorphous alloy. These cores provide high saturation flux density and very low losses as compared to other conventional magnetic material. These cores are suitable for power transformer or inductor used in high frequency applications.

Applications

  • Power factor correction chokes (UPS & SMPS)
  • UPS Harmonic filters
  • High frequency power transformer
  • Induction heating
  • Power supplies of welding equipment
  • Solar and Wind power generator

Benefits

  • High saturation flux density (1.25T)
  • Very low core loss – 1/5th of iron based amorphous Metal
  • Very low audible noise
  • Low temp rise due to very low losses
  • Smaller sizes
