3000 Watts Power Amplifier Class D Mosfet IRFP260 / IRFP4227

3000W CLass D Power Amplifier Circuit

3000W (3kW) Class D Power Amplifier Project using IC IR2110, CD4049 (HEF4049/HCF4049), NE555, LM311, and Op-Amp Comparator TL071 as the main stage amplifier, the driver stage using BD140/BD139 or you can use any driver stage power amplifier transistors. The Final Stage Amplifier using 4 x Mosfet Transistor IRFP260 or you can use IRFP250 / IRFP460 / IRFP4227. And do not forget to lose the importance of the LPF Filter.

The advantages of this high power amplifier are:

  • Strong Bass Boost, not Saggy
  • Secondary comfortable bias voltage (can be AC (transformer) / DC (adapter))
  • Highly Efficient Rail - Stack Layout
  • Oversized Heatsink & Output Coil (not easy saturation)
  • Pulse Resolution Adjust Enable
Below the Circuit Diagram of 3000W Class D Amplifier includes PCB Layout design:

Hello sir can i purchase class d 3000 amp pcb and all component ? Please reply me. My mailbid is mr.pranatoshdas@gmail.com

Hello sir, yes you can buy the pcb and components. i will sent you an email.

Can you give me a clear schematic of Class D 3000W Gambit?

you can download the high resolution of schematic and pcb layout at the links on google drive.

how can we increase more power? Is it possible to add more stages of mosfets or by increasing the power supply to 150 volts in the same circuit?

what are the uses of TL041 and 555 which one is making a clock pulse/ square wave generator?

You can increase voltage up to 100V , you cant adding more stages of final mosfet. But you can upgrade with replacing the mosfet with more Vgs Igd higher.

The Tl041 as a comparator circuit. And 555 as OCP circuit protection for it amplifier.

can I have the files of this amplifier? toreto009@mail.ru

This is real 3000watt rms? It is professional? Minimum 2 ohm impidance?
If is it true then i want to purchase it. Please contact me. My whatsapp no. +919851057311

Do you have a circuit board of this amplifier in .LAY format?

Yes it is real 3000w if you make with same as components list.

Please visit contact us page

What is the price complete audio board . and how to purchase please inform me. I am from india

I want to purchase complete audio board. What price and how to purchase . i am from india. Please inform me.

how can i purchase the PCB board for the 3000watts power amplifier with mosfet

looking at the lay out of your pcb board,how will you put the heat sink for the mosfets and will this circuit require a pre amp and power capacitors or its all with the board once assembly is complete?

for the heatsink, you must plase the mosfet on back of pcb. and put preamp on nput socket

IS THIS PCB LAY OUT ENOUGH FOR THE AMP TO BE COMPLETE ONCE ASSEMBLY IS COMPLETE OR WILL IT REQUIRE THE POWER CAPACITORS?

Sir I want 3000w amplifierr circut complete who sorce avialable lahore in pakistan

if you use smps u u dont require power capacitor. if you use conventional transformer you must use.

just if i may ask ,can i replace that inductor with a toroidal transformer?

No u cant using toroidial transformer for inductor.

Kindly send me your email.I want the PCB board for this 3000watts power amplifier.my email is jumaken99@gmail.com.can I use an air core inductor in place of that iron core inductor?

use iron core inductor, please contact me at contact us page.

I want to buy 3000 watt power stereo amplifier.

untuk menaikan daya power amply tersebut diatas 3000 watt.
Apakah yang harus dirubah dan ditambahkan pada skema pwer amply tersebut?

how can i purchase 3000w class d amp PCB

Hello sir can i purchase class d 3000 amp pcb and all component ? Please reply me. My mailbid is prageeth62@gmail.com

Bro pls tell me know the PCB size

where can I purchase a switch mode power supply suitable for this amplifier Australia 240v ac mains

Hi Wahyu ! I watched the video of the gambit 3 k watts class D amp and there seems to be missing parts : bd140 transistor and the final mosfet transistors. Has this board been tested to be fully functional ? Can you post a test video of this amplifier ?

Pls upload the circuit diagram of 3000w mosfect that is very clear. Thanks.

Hi sir. How can i order buy complete parts and pcb for this project? Thanks

Do i see it correct? I need +12 Volt, -12 Volt, +80V and -80V? All with the same common ground?

creo que hay un error en la parte del transistor 2n5401 figura como npn y es en realidad pnp asi ambien entre el positivo en su colector cuando deberia ser en su emisor pero en pnp del 2n5401

Hi, to obtain 3000w from this amplifier, what ACvoltage and Ampere transformer should we use?

sir,
please tell me acctual pcb size.

Mau tanya bos ukuran panjang sama lebar berapa ya.. . Trima kasih

Hi i want to purchase pcb board for this class d 3000w. Here is my email id: chixz_0579@yahoo.com

Xin chào pro, mình ở việt nam, mình đã xem rất nhiều dự án của pro và mình rất thích dự án này. Vậy pro có thể gửi cho mình danh sách thành phần, sơ đồ bố chí linh kiện cũng như pcb của dự án này bằng pdf không? chipcoi368@gmail.com

Xin chào pro, mình ở việt nam vì đam mê và yêu thích nen mao phep xin pro gui cho minh danh sach thanh phan, bo chi linh kien, pcb cua mach 3000W nay bang pdf. rat vui va cam on, cam on

sirkuit benar-benar bekerja tetapi dengan sadar dan rela membuat beberapa ketidakakuratan sehingga mereka tidak perlu permainan seperti itu untuk menjual pcb Anda harus mengeluh ke jaringan internet nasional 900 -1500- 2000 biridge penuh dan akhirnya 3000 watt dan tidak bekerja banyak uang saya menghabiskan semua sampah sangat disayangkan orang menipu sirkuit dengan benar dan berhasil sampai tidak ada yang mengganggu uang dan buang-buang waktu

Hi sir. How can i order buy complete parts and pcb for this project? Thanks
