Nanocrystalline Core Toroidal Transformer Core Product Description
Nanocrystalline based on nanocrystals less than 10 nanometer in their structure, therefore cores made by nanocrystalline are much superior than the other soft magnetic materials.
Nanocrystalline Core ring Core Feature
- Higher permeability
- Lower magnetization in higher inductions
- Low core losses especially at high frequencie
- Less losses on high temperatures
Nanocrystalline Core Toroidal Transformer Core Application
- Inverter welding equipments
- X-ray, laser, communication power supplies / UPS
- High frequency induction heating power supplies / Charging power supplies
- Frequency control of motor speed power supplies
- Plasma cutting machines
