150W OCL Power Amplifier

Friday, October 26th, 2018 - Audio Circuit

The circuit of 150W OCL power amplifier is a circuit of class AB amplifier. PCB to the circuit 150W OCL power amplifier can be purchased at electronics stores with several brands. Power supply for 150W OCL power amplifier This is a symmetrical DC voltage of ± 25 Volts to ± 42 volt power supply can be made with symmetrical in previous articles. For the maximum audio output power supply to the circuit 150W OCL power amplifier is minimal 5A. A complete range of 150W OCL power amplifier can be seen in the following figure.

The circuit of 150W OCL Power Amplifier

150W OCL Power Amplifier

The circuit of 150W OCL power amplifier as shown below using type power transistors 2N3055 and MJ2955 physical form such as a poultice. The power transistor can be replaced by transistors complement others, such as TIP3055 and TIP2955 so that it can more easily in cooler installation transistor for 150W OCL power amplifier.

Component L, Ra, Rb and C at the output 150W OCL power amplifier can be dispensed with. The power amplifier circuit above is still not equipped with a power supply circuit and a circuit regulator tone (tone control).

Output 150W OCL power amplifier

Circuit power amplifier type of OCL complementary just as in the picture above will cause the pulse instantaneous current at the output so that the resulting sound of the beat of the loudspeaker, which can damage the speaker when the ongoing, pounding on the speakers can be prevented by installing a circuit of speaker protector at the output of the circuit 150W OCL power amplifier.
