IRS2092S HiFi Power Amplifier Board 500W Mono Channel Digital Amplifier Class D

Product Description According to the power formula (P=U*U/R=Voltage*Voltage/Load), power is determined by voltage and load. Higher voltage and lighter load result in higher power. The board’s voltage range indicates the voltage within which the board will operate normally. Not all voltages and loads produce the maximum power output listed. For example, a 12V supply into a 4Ω load has a maximum power output of 15W, while a 24V supply into a 4Ω load has a maximum power output of 50W, while a 24V supply into a 4Ω load has a maximum power output of 25W. At all times, the power supply must be greater than the amplifier’s power. Otherwise, the amplifier will not be able to produce high volume, the power will drop, and the sound will be cut off, failing to achieve the desired power output. 1. Supply Voltage: Dual DC Power Supply ±58-70V 2. Rated Output Power: 500W (±65V into a 4-ohm load, 10% distortion) 3. Efficiency: >= 90% 4. Signal-to-Noise Ratio: 90dB 5. Total Harmonic Distortion: 380W (±65V into a 4-ohm speaker, <0.1% distortion) 280W (±65V into an 8-ohm speaker, <0.1% distortion) 6. Frequency Response: 20Hz-20kHz 7. Speaker: 4-8Ω 8. Voltage Amplification: 36x 9. Input Sensitivity: 1.5V (RMS) 10. Output Short-Circuit Protection: Yes 11. Output DC Bias Protection (Speaker Protection): Yes 12. Overtemperature Protection: Yes. Output will be shut down if the heatsink FET temperature exceeds 100°C. II. Usage Precautions: 1. The rated supply voltage is ±65V for dual power supplies. It operates normally within ±58—±70V (over 70V will cause burnout, and no coverage will be provided for burnouts!). If using a toroidal transformer, the voltage may fluctuate with the power grid due to lack of voltage regulation. Please allow for a margin when using the board. Ensure that the positive and negative poles of the power supply are connected correctly to avoid damaging the board. 2. A DC dual power supply with ±65V and good filtering is recommended. 3. 10-18-inch 4-ohm to 8-ohm speakers are recommended. 4. Although the audio output is short-circuit protected, avoid short-circuiting as much as possible. 5. Carefully check the wiring before applying power to ensure it is correct. 7. The voltage gain of this board is fixed at 40x. If the output power is insufficient, add a pre-amplifier as needed. The wiring diagram is as follows.
