500w Audio Power Amplifier Circuit Diagram. It uses 12x power mosfet irfp240. Diy 500w class d amplifier circuit using tl494 ic.

Diy 500w class d amplifier circuit using tl494 ic. The tl494 is a pwm ic will provide a high quality signal that helps to generate high quality audio signals. This is 500w rms power amplifier circuit design build based on mosfet.

It is a very good and powerful amplifier.

Circuit functional i use the 85 volt when the output current is supplied to the drive 350 to 340 very hot. And also the output audio diagram for 2 speaker s. Below describe the circuit diagram of 500w power amplifier. I think it is useful for you to apply the circuit with your sound devices.
