The better the permeability of nanocrystalline core, the smaller the measurement error and the higher the precision. Low ampere turns and small variable ratio are required. Nanocrystalline alloy transformer core is widely used in precision current transformers, zero-sequence current transformers, PFC, medium-high frequency transformers and other electrical equipment due to its excellent magnetic properties such as high permeability and high saturation magnetic inductance
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.
