Nanocrystalline Transformer Core Used In Inverter Welding Machine Power Supply
Applications
Inverter Welding machine power supply
X-ray, laser, communication power supply
UPS and high frequency induction heating power supply
Frequency control of motor speed power supply
Charging power supply
UPS
Performance
High Bs - Reducing volume and weight of the cores
High permeability and low Coercive force --Higher efficiency and
less excited power of transformer
Low Br (Br≤0.2T) - Higher magnetic flux density and output power
Low core loss - Lower temperature rising,higher efficiency of the
transformer
Keep stable working at -45℃ ~ 130 ℃ for long time.
