500w 1000w Toroidal Transformer 220v 240v 12v 35v Step Down
Toroidal Transformer
Product performance:
Feature:
1. The high-efficiency iron core has no air gap, and the stacking factor can be as high as 95%.
2. Less vibration noise. The iron core has no air gap, which can reduce the noise of the induced vibration of the iron core. The windings evenly and tightly wrap the annular iron core, which effectively reduces the "hum" sound caused by magnetostriction.
3. Low operating temperature Because the iron loss can reach 1.1W/kg, the iron loss is very small, the temperature rise of the iron core is low, and the winding has a good heat dissipation on the iron core with a lower temperature, so the temperature rise of the transformer is low.
4. Easy to install The toroidal transformer has only one mounting screw in the center, which is especially easy to quickly install and disassemble in electronic equipment.
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.
