2207 Square 600:600 1+1:1+1 Permalloy Audio Isolator Transformer For Sound System

1.Product Description:

600:600 1+1:1+1 Permalloy Audio Isolator Transformer is used as a component of circuits such as voltage amplification and power output in radio communication, radio and television, and automatic control. The frequency response of the audio transformer is uniform in the working frequency band. The core is made of high magnetic permeability materials. The primary and secondary windings are closely coupled, so that the magnetic flux passing through the primary winding is almost all linked with the secondary winding, and the coupling coefficient is close to 1. The lowest frequency of the passband is determined by the primary winding inductance, and the highest frequency is determined by the transformer leakage inductance. To ensure that the transformer has enough passband, the primary winding inductance should be large and the leakage inductance should be small. The hysteresis loss of the iron core and the saturation of the magnetic circuit can cause signal distortion. Properly configuring the load and increasing the load current can reduce the influence of hysteresis loss; increasing the core section and leaving an air gap can prevent the magnetic circuit from being saturated, which can reduce the distortion of the signal.

2.The role of 600:600 1+1:1+1 Permalloy Audio Isolator Transformer:

1. Audio signal coupling;

2. Realize the impedance matching of the front and rear stages;

3. Isolation of the front and rear DC power supply circuits.

1. High magnetic permeability: PoMo alloy material has extremely high magnetic permeability, which can efficiently conduct magnetism and make the transmission of audio signals smoother, and it can produce larger magnetic induction intensity under smaller magnetic field strength, which can effectively improve the efficiency and performance of the transformer, reduce the energy loss in the process of signal transmission, and ensure the completeness and accuracy of audio signals.

2. Low hysteresis loss: Hysteresis loss refers to the energy loss due to hysteresis phenomenon in the process of magnetization and demagnetization of magnetic materials. The transformer's PoMo alloy material has a narrow hysteresis return line and low hysteresis loss, which means that less heat is generated under the action of the alternating magnetic field of the audio signal, which reduces the waste of energy and improves the efficiency of energy utilization, and at the same time helps to prolong the service life of the transformer, reduces the heat generation of the equipment and improves the stability of the system.

3. Excellent isolation performance: the primary and secondary windings have good electrical isolation performance, can effectively isolate the potential difference between the equipment, stray current and electromagnetic interference, etc., to prevent external interference signals into the audio signal path, but also to avoid audio signals on other equipment to produce interference, to ensure that audio signals in the transmission process of purity and stability, to improve the audio system's ability to resist interference, for the Electromagnetic compatibility requirements of higher occasions.

4. High-precision turns ratio: 600:600 turns ratio and 1+1:1+1 winding structure design is more accurate to ensure the accurate proportionality between the input and output signals, so that the audio signal in the transmission and conversion process will not appear amplitude distortion or phase shift and other problems, to ensure that the quality and accuracy of the audio signal, and is conducive to the realization of balanced transmission of audio signals and matching to improve the overall performance of the audio system. The overall performance of the audio system.
