Advantages of ATO Toroidal Transformer

High Efficiency: Winding matches the core perfectly, which makes the transformer more efficient.
Long Service Life: With high-quality materials and manufacturing technology, the transformer can be used for 30 years.
Less Noise: The core is seamlessly rolled and the winding is set evenly over it, which makes the transformer quiet when it is working.
Less Radiation: Toroidal structure and winding technology reduce electromagnetic radiation.
Low Temperature Rise: Even if it is overloaded at 120%, the temperature rise will be less than 70℃.

Tips: The higher the power of toroidal transformer, the higher the efficiency

Toroidal transformer is a kind of step-up & step-down transformer power supply, which has the advantages of small volume, low noise, less heat and high performance. Generally, we use a variety of voltages, such as 220V for domestic lighting, 36V for industrial safety lighting, and the voltage of the welding machine needs to be adjusted. These cannot be separated from the toroidal transformer, which can step down the voltage we need through the principle of electromagnetic mutual inductance of the main and auxiliary coils.

The larger the rated power of the transformer, the higher the working conversion efficiency. The same 220V to 24V transformer with a rated power of 500VA has a working conversion efficiency of more than 92%, while the conversion efficiency of 50VA low power is only 85%. There is a clear difference between the two.
