Power Transformer Core - China

AT&M' the 2nd generation power transformer cores are made of Antainano®

ribbons with thickness of approx.

24μm.

It takes the advantage of

low core loss at high frequencies and can successfully work at frequency

range of 20~50KHz.

Comparing with the 1st generation products, the core

loss of the 2nd generation is lower and the volume is smaller under the

same working conditions.

The 2nd generation power transformer cores can

meet the development requirements of miniaturization, lightness and high

efficiency in power supplies industry.

Applications • Inverter welding

machines • X-Ray and laser source power supplies • Communication power

supplies • High frequency heating systems • Electrolytic and plating

power supplies

Characteristics

• 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 -55°C~130°C for long

time
