Applications

·         Transformer cores in switch mode power supplies at 400 - 20,000 Hz.                                     

·         Transformers for Inverters in Welding Equipment, Wind Turbines, and Solar Panels                Banding Tools

·         Output Filter Chokes in Large Switching Mode Power Supplies  

·         UPS harmonic inductors

·         High power ballasts

·         Power Factor Correction Chokes in UPS

 

Advantages Over Silicon Steel, Ferrite and Powdered Iron Cores

·         Approximately 50% lower Core Weight and Volume due to Higher Saturation Induction

·         Low Core Losses due to Ultra-Thin Lamination Thickness (1 mil = 25 µM)

·         Smaller Overall Design due to Low Temperature Rise

·         Fast Assembly into Pre-Wound Coils

·         Easily Adjustable Air Gap

·         Wide Operating Temperature Range (-55°C to 130°C)
