    High Efficiency Audio Toroidal Transformer

    Output transformer: used in audio equipment and broadcasting equipment, plays the role of impedance transformation in the circuit. Input transformer: the main function is in the input of sound signal when the occurrence of impedance conversion in the circuit. Interstage transformer: a common interstage transformer enables the various operating units in an amplifier to harmonize. Wire-to-wire transformer: wire-to-wire transformers are often used in wired broadcast equipment. Due to the cable broadcast on the work unit, there are often a lot of power amplifier, and the long lines, long distance transmission of audio will make the audio distortion. The structure of the ring audio transformer has high utilization rate, high stability, low loss and strong load capacity. Therefore, toroidal audio transformer is very suitable for installation in broadcast system.

  • Audio Toroidal Transformer For Audio Amplifiers

    1. High efficiency: the toroidal transformer core is made of continuous oriented silicon steel strip which is continuously wound. The winding is closely covered with the ring core for winding, and the magnetic flux density is high, so the toroidal transformer can achieve high electrical efficiency. 2, Small size: compared with the ordinary transformer, the toroidal transformer is only half the size of the weight. Saint-element toroidal audio transformer 3. Low noise: the annular core is continuously wound without cutting, so there is no air gap, which greatly reduces the mechanical noise. 4. Low no-load loss: the excitation current required by the toroidal transformer is much smaller than that of the ordinary transformer, so the no-load loss is very low. 5. Simple installation: the transformer can be firmly installed through the screw in the center of the ring transformer, which greatly saves the time of assembly and installation.
