IRS2092S Audio Power Amplifier Board Class D Mono 500W

1. Power Supply Voltage: Dual DC power supply 58V-70V, can operate normally within ±58V to ±70V (exceeding 70V will cause damage).
2. Rated Output Power: 500W (±65V power supply, 4-ohm load, 10% distortion).
3. Efficiency 4. Signal-to-noise ratio: 90dB
5. Total harmonic distortion:
380W (±65W power supply, 4 ohm speaker, distortion <0.1%)
280W (±65W power supply, 8 ohm speaker, distortion <0.1%)
6. Frequency response range: 20Hz-20KHz
7. Speaker: 4-8Ω
8. Voltage amplification: 36 times
9. Input sensitivity: 1.5V (RMS)
10. Output short circuit protection: Yes
11. Output DC bias protection (speaker protection): Yes
12. Over-temperature protection: Yes, output shuts off when the MOSFET temperature exceeds 100°C!

Precautions for use:
1. Rated power supply voltage is dual power supply. 1. The board can operate normally with a voltage range of ±65V, ±58V-±70V (any voltage exceeding 70V will cause damage, and we will not provide warranty coverage for damaged boards!). If the power supply does not have a voltage regulation function, the voltage will fluctuate with the mains voltage; please ensure sufficient margin. Do not connect the positive and negative terminals of the power supply incorrectly to avoid damage.
2. A DC dual power supply with good filtering at ±65V is recommended.
3. 10-18 inch 4-8 ohm speakers are recommended.
4. Although the audio output has short-circuit protection, please avoid short-circuiting it as much as possible.
5. Please carefully check before powering on to ensure that the wiring is correct.
7. The voltage amplification factor of this board is fixed at 40 times. If the output power is insufficient, add a preamplifier as needed.
