Overview:
This audio amplifier board employs IR&39;s High Voltage, high performance class D audio amplifier driver IRS2092SPBF and 200V Single N-Channel HEXFET Power MOSFET IRFB4227.
This amplifier board supports stereo amplification by using two channel half bridge topology.
By means of dedicated heatsink design with temperature controlled fan,it is capable of delivering dual channel maximum power 500W RMS @ 4ohm simultaneously without extraordinary heatsink.
Besides of built-in chip protection, ESD and spike protection components used throughout input and output of the amplifier board ensure its robustness and reliability.
Hear your music like never before with 500 Watts per channel of audiophile-grade Tripath Class-T technology. Amp includes a quiet running fan to keep things cool.
