Description
Trafo Toroid 220v 230v 100VA 200VA 300VA 500VA 1000VA is a major type of electronic transformer, which has been widely used in household appliances and other electronic equipment with high technical requirements. Its main purpose is as power transformer and isolation transformer. The complete series of ring transformers have been widely used in computer, medical equipment, telecommunication, instrument and lighting. In the past ten years, China’s ring transformers have developed from scratch. So far, they have formed a considerable scale of production. In addition to meeting domestic demand, they are also exported in large quantities. In China, it is mainly used in audio equipment, automatic control equipment and quartz lamp lighting of household appliances.
Parameters
Specifications
Trafo Toroid 220v 230v 100VA 200VA 300VA 500VA 1000VA
1. Operating frequency: 10khz-200khz
2. Output power: customized
3. Operating temperature: -40℃ to +125℃
4. Storage temperature: -25℃ to +85℃
5. Storage humidity: 30 to 95%
The characteristics:
1. The electric efficiency is high, the core has no air gap, the Du stack factor can be as high as 95%, the permeability of the core can be 1.5 ~ 1.8T (the laminated core can only be 1.2 ~ 1.4T), the electric efficiency can be as high as 95%, and the no-load current is only 10% of the laminated core.
2. As long as the cross-sectional area of the core is kept equal, the ratio of the length, width and height of the core can be easily changed, and the required overall size can be designed.
3. The core of Trafo Toroid has no air gap, and the winding is evenly wound on the ring core. This structure leads to small magnetic leakage and small electromagnetic radiation. Without additional shielding, it can be used in high-sensitivity electronic equipment, such as low-level amplifier and medical equipment.
4. There is no air gap in the core, which can reduce the induced vibration noise of the core. The winding is even and tightly wrapped around the ring core, which can effectively reduce the “buzz” caused by magnetostriction.
5. The operation temperature is low, 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 heat dissipation of the winding on the lower temperature iron core is good, so the temperature rise of Trafo Toroid is low.
6. It is easy to install the Trafo Toroid . There is only one mounting screw in the center. It is especially easy to install and disassemble the toroidal transformer in electronic equipment.
The Applications
1. Audio equipment
Among theTrafo Toroid 220v 230v 100VA 200VA 300VA 500VA 1000VA products of the factory, there are well-known products used in audio equipment. For example, it can be used in three kinds of high-power high fidelity amplifiers as high-performance products of power transformer and power transformer for medium and small power audio equipment. The power range from 6va to 1000VA can use high-quality ring transformer.
2. Electrical control
Such as for current and voltage transformers. High precision and high stability transformer made by ring transformer technology. New high performance magnetic materials such as permalloy soft magnetic material, amorphous material or nanocrystalline alloy can be used as the magnetic core, with precision intelligent instrument and special test method. It can ensure that the parameters of the transformer are accurate and the performance is completely consistent.
3. Medical equipment
Trafo Toroid 220v 230v 100VA 200VA 300VA 500VA 1000VA specially designed and manufactured for medical equipment. In addition to high efficiency, high reliability and high safety requirements. In addition, the anti electric strength and damp heat resistance are enhanced. It is required to add heating fuse inside the transformer to ensure reliability.
4. Other applications
Trafo Toroid 220v 230v 100VA 200VA 300VA 500VA 1000VA can also be used in all kinds of power inverter, such as solar, wind power generation system. This kind of high efficiency ring transformer with low loss core can greatly improve the overall efficiency of the inverter.
