Amplifier Audio Toroidal Power Transformer 1500W 48V 45 0 45 24-0-24 50 0 50v 50/60hz
Product performance:
The principle of the toroidal transformer is the same as that of the transformer, both of which are based on the basic principles of electro-magnetic and magneto-electric conversion.
Application:
Audio equipment
Among the toroidal transformer products of this factory, there are first and foremost products that are well-known in audio equipment. Such as high-performance products that can be used as power transformers in Class 3 high-power hi-fi amplifiers and power transformers for medium and small power audio equipment. High-quality toroidal transformers can be used for power ranges from 6VA to 1000VA.
Product advantages:
The core of the toroidal transformer is made of high-quality cold-rolled silicon steel sheets (generally below 0.35mm in thickness), which are seamlessly rolled, which makes its core performance better than the traditional laminated core. The coil of the toroidal transformer is evenly wound on the iron core, and the direction of the magnetic field lines generated by the coil almost completely coincides with the magnetic circuit of the iron core. Compared with the laminated type, the excitation energy and core loss will be reduced by 25%, which brings the following series of The advantages.
1) The iron core with high electrical efficiency 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 can be as high as 95% or more, no-load The current is only 10% of the laminated type.
2) Small size and light weight Toroidal transformers can reduce the weight by half compared to laminated transformers. As long as the cross-sectional area of the core is kept equal, the toroidal transformer can easily change the ratio of the length, width and height of the core, and can be designed to meet the requirements.
3) The magnetic interference is small. The toroidal transformer core has no air gap, and the windings are evenly wound on the toroidal core. This structure leads to small magnetic flux leakage and small electromagnetic radiation. High-sensitivity electronic equipment can be used without additional shielding. , such as low-level amplifiers and medical equipment.
4) Less vibration and noise, the iron core has no air gap, which can reduce the iron core
