1,500 watts of clean monoblock power are available with this amplifier board. It integrates high performance IRS2092 and IR MOSFET IRFB4227 supporting single channel audio amplification.
Highlights
- Self-oscillating half-bridge topology with optional clock synchronization
- Capable of 1500W RMS output @ 2 Ohm continuously
- Requires 55 to 75 VDC power supply
Product Details
Sure Electronics AA-AB31411 1x1500W Class D Audio Amplifier Board – IRS2092
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.
This amplifier board also includes a myriad of protection features: over current, over/under voltage, DC output, and temperature protection circuits are built-in. It can be bridged with another amplifier board for higher output, around 3000W RMS @ 4 Ohm, without external circuitry. Suitable for high-end / high power sound systems like disco, active speakers, large subwoofers for PA (Professional Audio), high power studio monitors and high power hi-end hi-fi systems.
