This audio amplifier board employs the high-voltage IR, IRS2092SPBF high-performance class D audio amplifier driver, and 200V single N-channel HFETFET IRFB4227 power MOSFET. This amplifier board supports stereo amplification using two-channel half bridge topology.
Thanks to the dedicated heatsink design with temperature controlled fan, it is capable of delivering the maximum dual channel power 1000W RMS @ 2ohm simultaneously without using an additional heatsink. In addition to the chip's built-in protection, ESD and discharge protection components used throughout the amplifier board's input and output ensure its robustness and reliability. Recommended power supply: ALC24V6AJ.
