HS4369 IRS2092S High power 500W Class D HIFI digital power amplifier board finished mono/super LM3886

According to the power formula p=u*u/r= voltage * voltage / load, the power is determined by the voltage and load. The higher the voltage is, the smaller the load is, the greater the power is. The voltage range of the board refers to the voltage within this range. The board can work normally. Not all the voltage and load power are so high-power output as the standard. For example, 12V power supply 4 Euro load, 15W higher power, 7.5W higher power at 8 euro; 24V power supply 4 Ω, power 50W, 8 Ω 25W; At any time, the power supply power must be greater than the power of the power amplifier, otherwise the high volume will not move, the power will be reduced and cut off, and the corresponding power output will not be achieved. 1. Power supply voltage: dual DC power supply &; 58---&; 70V
2. Rated output power: 500W (&; 65V power supply, 4 Ω load, distortion 10%)
3. Efficiency: > =90%
4. Signal to noise ratio: 90dB
5. Total harmonic distortion: 380W (&amp;; 65 power supply 4-ohm horn, distortion <0.1%)
280W (&amp;; 65 power supply 8 Ω horn, distortion <0.1%)
6. Frequency response range: 20Hz-20KHz
7. Horn: 4-8 Ω
8. Voltage magnification: 36 times
9. Input sensitivity 1.5V (RMS)
10. Output short circuit protection: Yes
11. Output DC bias protection, namely horn protection: Yes
12. Over temperature protection: Yes, if the temperature of the radiator FET is higher than 100 ° C, turn off the output! 2、 Precautions for use:
1. The rated power supply voltage is dual power supply &amp;; 65V, voltage at &amp;; 58---&amp;; 70V can work normally (if it exceeds 70V, it will burn, and if it burns out, it will not be covered!), If it is huanniu, the voltage will fluctuate with the power grid because it does not have the voltage stabilizing function. Please use yes to leave margin. Do not connect the positive and negative poles of the power supply incorrectly to avoid burning the board
2. DC dual power supply is recommended &amp;; 65V power supply with good filtering
3. It is recommended to use 10-18 Inch 4 Ω -8 Ω speakers for speakers
4. Although the audio output has short circuit protection, try not to short circuit
5. Please check carefully before power on to ensure that the wiring is correct before power on.
7. The voltage amplification factor of this board is fixed at 40 times. If the output power is not enough, add the previous stage amplification according to the specific situation.
