Amorphous Power Transformer Cores have Harmonious and beautiful dimension,small overlooking area,and better economical efficiency of product structure.

Characteristics  

  • High saturation induction of 1.56 Tesla—Reducing component volume.

  • Low coercivity—Increasing component efficiency.

  • Low core loss—Reducing temperature rise in devices.

  • Variable permeability by different heat treatments—Satisfying various application requirements.

  • Excellent thermal stability—Having a highest service temperature of 130oC.
