    The provided cheap price toroidal transformer is 2500VA, works at 50Hz/ 60Hz low frequency circuit, with a primary voltage of 120V AC and twin secondary voltage of 2x15V, twin secondary windings may be connected in series or parallel or used independently.

    Advantages of ATO Toroidal Transformer

    1. High Efficiency: Winding matches core perfectly, which makes the transformer more efficiency.

    2. Long Service Life: With high quality materials and manufacturing technology, the transformer can be used for 30 years.

    3. Less Noise: The core is seamlessly rolled and the winding is set evenly over it, which makes the transformer quiet when it is working.

    4. Less Radiation: Toroidal structure and winding technology reduce electromagnetic radiation.

    5. Low Temperature Rise: Even it is overloaded at 120%, temperature rise will be less than 70℃.

    Tips: Select the right core structure of transformer

    The iron core of the toroidal transformer, cold-rolled silicon steel with a thickness of 0.35 mm or less, is seamlessly rolled. The coil is uniformly around the core, and the direction of the magnetic field lines caused by the core almost coincides with the core, so that the eddy current loss generated by the AC current through the coil is minimized. For example, the core loss of E-type transformers exceeds 50%, so as to improve the conversion efficiency of transformation or isolation, thus being often used in switching power supply solutions.

    The core of the toroidal transformer can be deepened without air gap, which is a good choice for switching power supplies or power adapters. The stacking factor can be as high as 95%, and the core magnetic conductance can take 1.5 to 1.8 T. Therefore, the electrical conversion efficiency of the toroidal transformer can reach more than 95%. This is the core structure of the transformer without breath, which can make the reactive current very small, and there is no heat generation in the long-term power situation.
