Feature:

*Core material and grades: Fe-based nanocrystal ,1k107A

*Core impregnation by epoxy , and glass fiber tape and PI tape winding outside of core.

*High Bs, low Br. Bigger flux gain △B, minimizing the volume of transformers

*High permeability, low coercive force. Low exciting power, high efficiency.

*Low core loss. Reducing temp.-rising,increasing efficiency.

*High curie temperature ,superior temperature stability.

*Optimum working frequecy :5KHz~30KHz

*Continuous working temperature range: -50~+130℃.

 

Application:

*Power tansformers for Switched mode power supply. such as ups.

*Main transformers for HF welding equipment. Such as inverter welding machine, plasma.

*Power transformers for Electrolytic and plating power supply.

*Power transformers for Induction heating system. Such as Mid-frequency furnace.

* Water cooled-power transformers for special power supply
