EI28 Split Core Current Transformer  

EI28 Split Core Current Transformer Audio transformers can implement voltage transformer conversion like power transformers, and can also implement audio signal coupling. There are four main functions of audio transformers: Audio output transformer: used in audio equipment and playback equipment, it plays an impedance transformation role in the circuit. Audio input transformer: The main function is when the sound signal is input, and it plays the role of impedance transformation in the circuit. Interstage transformer: The common interstage transformer can make all levels of working units in the amplifier reconcile. Line-to-line transformers: line-to-line transformers are often used in cable broadcasting equipment. Because there are often many high-power amplifiers on the working unit of cable broadcasting, and the line is long, the long-distance transmission of audio will distort the audio. Audio tr…
