Description:
- Class D Amplifier finished board
- IRAUD2000,IRAUD2000 IRFB4227 7G31A-22UH
- 184mmX117mmX70mm / block ( already with mounting studs )
- finished board one , to see is to get .
- fever amplifier stage or KTV amplifier, home theater multi-channel amplifier, car amplifier and battery -powered high-power amplifier ( needed boost equipment )

[Note]
1) Amplifier with overcurrent and short circuit protection , thermal protection and over-voltage protection , safe and reliable ! To improve security, the proposed increase of share speaker protection circuit , just in case.
2) High-voltage power amplifier operating in the state ( DC voltage > 60V), the inductor and the radiator will be slightly hot , if poor ventilation ( eg in a sealed box ) , should be added to enhance the cooling fan .
3) If prolonged power output , rectifier bridge requires external heat sink , the other proposes to add auxiliary cooling fan .
4) This amplifier is a dual -channel design , can be bridge .
5) Amplifier board if it is installed in the speaker , it should be as far away from the speaker , the best shielding .
6) To DC power amplifier board , the board did not take the rectifier bridge, need additional rectifier bridge, and should be added to the rectifier bridge heatsink .
