HighlightsSelf-oscillating half-bridge topologyCapable of 3000W RMS output @ 4 Ohm continuouslyRequires 55 to 75 VDC power supply Product DetailsSure Electronics AA-AB31341 1x3000W IRS2092 4 Ohm Class D Audio Amplifier Board 3,000 watts of clean monoblock power are available with this amplifier board. It integrates high performance IRS2092 and 200V Single N-Channel HEXFET Power MOSFET IRFB4227 supporting single channel audio amplification by using one channel half bridge topology. Two 55 to 75 VDC high-voltage power supplies are required for operation; each power supply dedicates its full output potential to a single rail for maximum output. This results in increased high-fidelity output, high dynamic range, low distortion, and a wide 20 to 22,000 Hz frequency response.ELECTRICAL SPECIFICATIONSSpecifications typical @ +25℃ , Powered by 72V DC, unless otherwise noted.
