  • Power Transformer Core - China

    price: contact company for price

    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
