Description
The transformer can interfere with the amplifier through magnetic field, electromagnetic induction and circuit. It is the biggest interference source in the audio machine. Therefore, to deal with its working state and application environment, the interference generated by the power transformer can be effectively avoided, so that the amplifier can be obtained. Excellent sound.
 
In addition to powering the amplifier, the power transformer can also couple the amplifier to the power supply, so that the interference source in the power grid enters the amplifier, and also reflects the voltage and current changes generated by the amplifier into the power grid. In order to cut off the electrostatic field and capacitive coupling between the windings, the isolation and common mode suppress the resulting interference, avoid coupling the common mode voltage in the grid or circuit to the secondary or primary, and add windings to the audio power transformer. Electrostatic shielding is critical. The shield can be an alternating layer of copper foil or a complete joint structure. In general, the better the windings (especially for the primary winding), the better the common mode rejection.
 

The core of a high-quality acoustic transformer has a high magnetic permeability and a high magnetostrictive effect. It is sensitive to the influence of external magnetic fields, pressure and vibration, and can generate additional voltage and cause interference. To this end, Sichuan Chongzhou Hengda Electronics developed the enthusiast-class iron shell potting audio transformer, is a product tailored for high-end audio equipment, effectively shielding electromagnetic interference and electromagnetic noise, is the best for high-end audio manufacturers select. Its main features are:
 
1. The iron shell encapsulation shell is made with precision, the electromagnetic shielding effect of 1.5 mm wall thickness is much better than the wall thickness of 0.8-1 mm; grasping the acoustic characteristics, targeted design, using high-core iron core, precise control of annealing process, electromagnetic interference Reduce by more than 90%;
 
2. Using double shielding technology to completely eliminate electromagnetic noise and electromagnetic interference, the speaker is not listening to any sounds;
Mold restrictions, the size of the shape can be adjusted to meet your individual needs.
 
Since 1994, Sichuan Chongzhou Hengda Electronics, devoted itself only to the R&D and manufacture of power transformer/electronic transformer/saftey transformer/isolation transformer/control transformer/audio transformer/stepup transformer/stepdown transformer/toroidal transformer/EI transformers/encapsulated transformer/central potted transformer/pcb transformer/pin transformer/cable transformer/current transformer/low voltage transformer/inductor/transformer toroidal core/transformer lamination core for over 20 years.
