nanocrystalline core

Short Description:

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.
