Application field: Public Address Amplifier
The transformer is widely use in the Stage amplifier, KTV, Public Address System and other professional amplifier. According to the main power request of Amplifier, it requests the transformer is with high efficiency, small loss, Low interference resistance, small magnetic leakage, No static current sound, sufficient power, low temperature rise.
For the amplifier transformer, customer very care about the interference issue. The raw material using and processing technology are very important to improve interference.
The main material core, what we use is 0.23mm high magnetic flux, low loss oriented silicon steel core. With this core, the transformer’s static loss is low.
Using CNC automatic arrangement technology, strengthen the coupling between winding and winding. Reduce leakage of internal magnetic field of winding.
