1000va Toroidal Transformer For Audio Amplifiers 220v 24v Toroidal Transformer

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.

Classification:

1. Standard power transformer products:

The capacity of the series is 8~1500VA, with a small voltage regulation rate, and the temperature rise at full load is only 40°C, allowing short-term overload operation, which is suitable for applications with high requirements. The primary and secondary windings are insulated with B-grade (130°C) polyester film, and at least three layers of insulating tape are required to withstand the withstand voltage test of AC 4000V for 1min.

2. Economical power transformer products

The capacity of the series is 50～1500VA. On the basis of ensuring the performance, we strive to reduce the cost. It is suitable for continuous operation without overloading. The operating temperature rise is 60℃, and the insulation material grade is A (105℃). When the output is full, the output The voltage error is less than 3%.

3. Isolation transformer products

Series capacity 50 ~ 1000VA, can be divided into two series for industrial and medical equipment. The isolation transformer focuses on its insulation performance. The primary and secondary are wrapped with at least 4 layers of B-class insulation polyester film, and the breakdown voltage is greater than 4000V. All primary leads must be double-insulated wires. The maximum temperature rise of the transformer is lower than 45℃.

4. Medical isolation transformers

In addition to meeting the above requirements, the isolation transformer for medical use should also meet the UL544 standard, that is, the primary and secondary windings should have thermal protection, and the distance between the winding and the ground copper shield should be greater than 13mm.

Application:

1. 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.

2. Electrical control

Such as for current and voltage transformers. High precision, high stability transformer made by toroidal transformer process. New high-performance magnetic materials such as permalloy soft magnetic materials, amorphous materials or nanocrystalline alloys can be used as magnetic cores, with precise intelligent instruments and special testing methods. It can ensure accurate transformer parameters and completely consistent performance.

3. Medical equipment

Toroidal transformers specially designed and manufactured for medical equipment. In addition to high efficiency, high reliability and high safety requirements. It also specially strengthens the electrical strength and improves the anti-humid heat performance. A thermal fuse is also required to be added inside the transformer to ensure reliability.

4. Application in other fields

Toroidal transformers can also be used in power inverters of various sizes, such as solar and wind power generation systems. This high-efficiency toroidal transformer with a low-loss iron core can greatly improve the overall efficiency of the inverter power supply.

Advantages of Toroidal Transformers:

1. 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;

2. 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;

3. 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;

4. Less vibration and noise

The iron core has no air gap, which can reduce the iron core.
