60va Audio Toroidal Transformer 12v Single Amplifier Power Supply Transformer

Product performance:

The working principle of a toroidal transformer is essentially the same as that of a transformer.

The iron core of the toroidal transformer is made of high-quality cold-rolled silicon steel sheet (the thickness of the sheet is generally less than 0.35mm), which is rolled seamlessly, which makes the performance of the iron core better than the traditional laminated iron core.

The coil of the toroidal transformer is evenly wound on the core, and the direction of the magnetic field lines generated by the coil almost completely coincides with the magnetic circuit of the core. Compared with the laminated type, the excitation energy and core loss will be reduced by 25%.

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.

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.
