Product Description
Direct Sale Customized Toroidal Transformer For Medical Equipment, Audio
1.Product performance:
Toroidal transformer is a large type of electronic transformer and has been widely used in home appliances and other electronic equipment with high technical requirements. Its main use is as a power transformer and an isolation transformer. Toroidal transformers have a complete series abroad and are widely used in computers, medical equipment, telecommunications, instruments and lighting. China's toroidal transformers have grown from nothing in the past ten years, and have formed a considerable scale of production so far. In addition to meeting China's domestic demand, they are also exported in large quantities. China is mainly used in audio equipment and automatic control equipment for home appliances, as well as quartz lamp lighting and so on.
2.Advantages of Toroidal Transformers:
High electrical efficiency
The core has no air gap, the stacking coefficient can be as high as 95% or more, the magnetic permeability of the core can be 1.5~1.8T (the laminated core can only be 1.2~1.4T), the electrical efficiency is as high as 95% or more, and the no-load current is only the laminated type. 10% of;
Small size and light weight
The weight of the toroidal transformer can be reduced by half compared to the laminated transformer. As long as the cross-sectional area of the iron core is kept equal, the toroidal transformer can easily change the ratio of the length, width and height of the iron core, and can be designed to meet the required external dimensions;
Less magnetic interference
The core of the toroidal transformer has no air gap, and the windings are evenly wound on the toroidal core. This structure leads to low magnetic flux leakage and low electromagnetic radiation. It can be used in high-sensitivity electronic equipment without additional shielding, such as applications in low Level amplifiers and medical equipment;
Less vibration and noise
The iron core has no air gap, which can reduce the iron core.
