IRFP4227 IRS2092S Digital Amplifier Mono 2000W HIFI power Amplifier board
Notice: 1. The rated power supply voltage is ±75V for dual power supply and ±58---±85V for voltage. (If it is a power frequency transformer, please leave a margin when the voltage fluctuates. The power supply is 3 power supply lines. Do not connect the positive and negative poles of the power supply to avoid burning. Bad board 2. Power supply is recommended for DC dual power supply ±75V filter better power supply 3. Speaker recommended 10-25 inch 2 ohm-8 ohm speaker 4. Although the audio output has short circuit protection, try not to short circuit. 5. Please check carefully before powering on, to ensure that the wiring is correct before power can be applied. 7. The voltage amplification factor of this board is fixed at 40 times. If the output power is not enough, add the preamplifier according to the specific situation. Parameters : 1. Power supply voltage: dual DC power supply ±58---±80V 2. Maximum rated output power: ±70V power supply bridge mono mode: 2000W (4 ohm load) 1200W (8 ohm load) ±70V power supply bridge stereo mode: 2X700W (4 ohm load) 2X350W (8 ohm load) 3. Efficiency: >=90% 4. Signal to noise ratio: 90dB 5. Total harmonic distortion: 2000W (±70 power supply 4 ohm bridge mode, distortion <1%) 500W (±85 power supply 8 ohm speakers, distortion <1%) 6. Frequency response range: 20Hz-22KHz 7. Voltage amplification: 45 times 8. Static power consumption: 8W 9. Input sensitivity 1.1V (RMS) 10. Output short circuit protection: Yes 11. Output DC bias protection is speaker protection: Yes 12. Over-temperature protection: Yes, the temperature of the radiator FET is higher than 100 °C, and the output is turned off! 13. Power amplifier board size: length x width x height = 135x132x45mm 14. Weight: 550 g If it is not the power supply of the switching power supply, it is necessary to add the rectifier filter circuit by the power supply of the ring cattle! If your switching power supply is not a dual output but a single output, you need two single power supplies in series. This board is a full-frequency pure final stage power amplifier. It needs to be used as a subwoofer to add a pre-stage low-pass filter. The board is powered by dual DC voltage. The car battery cannot be used as a single power supply. It needs to be powered by a car amplifier
