Customized 120W Pure Copper Low Frequency Power Supply Single Phase Toroidal Isolation Transformer For Audio Amplifier

Customized 300W pure copper wire toroidal transformer low frequency transformer for audio amplifiers

1.Product Performance

The iron core of the toroidal transformer is made of continuous oriented silicon steel strips. After annealing, a highly consistent magnetic flux guidance will be formed. The pass density is higher because the toroidal transformer can achieve a high electrical efficiency of 95%.

2.Product Feature

a. The high-efficiency iron core has no air gap, and the stacking factor can be as high as 95%.

b. 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.Application

a. 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.

b. 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.

c. 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.
