2x500Watt Class D Audio Amplifier Board -IRS2092

2x500Watt Class D Audio Amplifier Board -IRS2092

Model: (AUD-00020)
Status: Unavailable
 Overview：
 
This audio amplifier board employs IR'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 750W 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.
