1500W HiFi Power Amplifier Circuit

Circuit Power Amplifier has a power output of up to 1500W RMS, power amplifier circuit is often used to power sound systems needed to outdor. In a series of images can be seen the final power amplifier uses 10 sets of large power transistors for the ending.

This power amplifier circuit using a transistor amplifier starting from the front, signal splitter, driver and power amplifier. Current consumption required is quite large power amplifier that is 15-20 A for this 1500W power amplifier circuit. Supply voltage needed by the power amplifier in order to work optimally is symmetrical 130VDC (130VDC ground-+130 VDC). 1500W amplifier circuit below is a picture series of mono, if you want to create a stereo it is necessary to make 2 copies of the circuit. For more details can be viewed directly image following a series 1500W power amplifier.

1500W HiFi Power Amplifier with Transistors

In the above series 1500W power amplifer has been equipped to control the DC Offset function to set the power amplifier when turned on and no input signal then the output should 0VDC. Then it is also equipped with a bias flow regulator to the power amplifier. The final power amplifier section requires that sufficient coolant to absorb heat generated. Power amplifier is not equipped with speakers protectors, therefore it should diapsang speaker protector on the output for when the power amplifier is turned on does not happen the beat to the speakers that may damage the speaker.

300W Mosfet power amp OCL HIFI Class AB by K1530 J201

Younger student brother will take an interest to do electronics project sends a teacher. Then come to consult with me. He wants to build Mosfet power Amplifier 300W rms model the stereo Amp. Which be the character OCL the sound is good. I then try to seek the circuit gives him sees in rows the way , accidentally meet this circuit. which design by Anthony.E.Holton.

He designs this circuit well. Use power 2SK1530+2SJ201 MOSFET x 4 jigsaw puzzle parallel amounts. make have power amplify tall arrive at about 300W rms true power FULL watt. Detail other part want friends see in original circuit.
