    High quality open style toroidal transformers is 200VA power capacity, 1-phase, a single 230V/50-60Hz primary winding, designed to step down 230V to dual 24V output, high insulation strength, UL recognised, widely use in control circuits and general applications.

    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℃.

    Toroidal transformer is also a small isolation transformer, with isolation function. Isolation transformers are necessary in medical equipment mainly because they can reduce leakage current and ensure that patients, doctors and others will not get an electric shock when they come into contact with the equipment, especially direct leakage of electricity to the heart.

    The damage and risks of current leakage to human body depend on the part and organ that leakage current passes through. However, when the current intensity to an important organ affects the function of the organ, your life will be in danger, especially for vital organs such as the brain and heart, which are extremely dangerous.

    The isolation transformer can just solve this problem, which is widely used in medical equipment because of its unique functional characteristics, especially in critical places, such as operating room, cardiac monitoring room, intensive care unit and so on. By using the isolation transformer, the leakage current in the power supply circuit can be effectively prevented from entering the operating room through the grounding wire, which greatly protects the patients from being injured by the leakage current.

    Compared with ordinary transformers, toroidal transformers have great advantages in efficiency, temperature rise, cost, anti-interference, and longevity. This video will showcase its function and benefits.
