Nanocrystalline Toroidal Cores For High Power Transformer On Inverter Welding Machine - China

High Frequency Power Transformer Key Properties:

·High saturate induction reduce volume of transformers

·High permeability and low coercivity improve efficiency, ·lower exciting power and reduce copper loss

·Low core loss reduce temperature rise of transformers

·Excellent thermal stability with the serving temperature of -55C-130C for long time

·Lowest core Loss : P <6W/Kg @ 20KHz, 0.5T, P<9W/Kg @ 20KHz, 1T, P<5W/Kg @ 35KHz, 0.5T, P<14W/Kg @ 35KHz, 1T
