Modul Amplificare Sure Electronics AA-AB31512

If you absolutely have to have 500 clean watts of stereo power, look no further than this amplifier board. It integrates high performance class D audio amplifier driver IRS2092SPBF and 200V Single N-Channel HEXFET Power MOSFET IRFB4227 by using one channel half bridge topology. HighlightsSelf-oscillating half-bridge topologyCapable of 500W RMS output @ 4 Ohm continuouslyRequires 55 to 65 VDC power supply Product DetailsSure Electronics AA-AB31512 1x500W IRS2092 4 Ohm Class D Audio Amplifier Board If you absolutely have to have 500 clean watts of stereo power, look no further than this amplifier board. It integrates high performance class D audio amplifier driver IRS2092SPBF and 200V Single N-Channel HEXFET Power MOSFET IRFB4227 by using one channel half bridge topology. Two 55 to 65 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 60V DC, unless otherwise noted.
