Product Details

Nanocrystalline cores for high frequency large power Transformers

Nano crystalline material is one kind of amorphous material. Nanocrystalline cores for high frequency and high power transformers have high saturation flux density, high permeability, low core loss, low saturation magnetostriction and good temperature stability. Widely used as main transformer cores for uni-polar, push-pull or bi-polar type high frequency and high power switched mode power supply.

High saturation flux density and low core loss are the primary demand of a transformer, and nanocrystalline core has the both properties. Transformers with nanocrystalline cores have features of small size, high efficiency, low loss, low temperature rise and excellent temperature stability.

Though we use 2nd generation nanocrystalline materials to make cores for nano crystalline transformer, we still proide low price nanocrystalline core, which used 1st generation ribbon, they still have very good performance.

Core dimensions and Power capacity:

64*40*20 1-3KW

80*50*25 4-6KW

100*60*20 6-8KW

120*70*20 7-12KW

120*70*30 12-15KW

130*80*40 15-20KW

130*80*50 20-25KW

Applications

>> Inverter welding machines

>> Electrolytic plating power supplies

>> High Power Laser power supplies

>> Communication, high-speed railway power supplies

>> High frequency heating systems

>> High frequency and high power switched mode power supply

Features

>> High saturation flux density - you can reduce volume of transformers vs tranditional Ferrite

>> High permeability - improve efficiency,lower exciting power and reduce copper loss

>> Low coercivity and Low core loss - low temperature rise

>> Excellent thermal stability - working temperature of -40 - 130℃
