500W 55-80V IRS2092S Mono Audio Amplifier

NOTE: A symmetrical + gnd - power supply is required for proper operation; a standard power supply is not suitable. We offer symmetrical power supplies with different voltages in separate auctions.

We offer a high-performance, single-channel Class D power amplifier based on the IRS2092S integrated circuit. It is an ideal solution for building efficient audio systems, e.g. for subwoofers or speaker sets.

Key features and benefits:

• Power and precision: Provides clear sound with up to 500W of power and very low distortion (THD <0.1%).
• Effective cooling: A large heat sink with a fan actively dissipates heat, ensuring stable operation even under full load.
• Complete protection: The module protects against speaker output short circuits and overheating (automatic shutdown at ~100°C).
• High efficiency >90%: This means less energy loss and less heat generation.
• Durable connectors: Screw terminals facilitate a secure and trouble-free connection of the power supply and speaker.
• Recommended for: 10-18" speakers with an impedance of 4-8 ohms.

Technical specifications:

• Chip: IRS2092S

• Power supply (optimal): Balanced DC +/-65V to +/-70V (3 wires: +, -, GND). A high-performance linear power supply is required.
• Output power: Up to 500W (depending on voltage and impedance)
• Frequency response: 20Hz - 20kHz
• Protections: Short-circuit, thermal
• Dimensions: 100 x 50 x 30 mm
