30A 100V 35000uF Fast Recovery Rectifier Capacitor Bank Board - L




This stereo Class D 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. Each channel is capable of producing up to 1000W into 2 Ohm load. Two channel half bridge topology is used to support stereo amplification. By means of dedicated heatsink design with two temperature controlled fans, it is able to maximize heat dissipation. High reliability is ensured due to a myriad of protection features such as over current, over/under voltage, DC output and over temperature protection.
