Description

This stereo Class D audio amplifier board employs IR's High Voltage, high performance class D audio amplifier driver IRS2092 to achieve high efficiency up to 95%. Each channel is capable of producing up to 500W into 4 Ohm load. Two channel half bridge topology is used to support stereo amplification. By means of optimized 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.
