1700W HIFI High Power IRS2092 Class D Mono Digital power amplifier board

Description

Description：
Designed with American digital audio IRS2092S, rated power 1700W
This HIFI digital power amplifier has been improved and developed by the engineers for a long time. The  HIFI Class D power amplifier board is improved. The whole board is matched with AVX tantalum capacitor, ELNA blue robe stepless audio capacitor, imported high frequency capacitor and other high-end components, sound mellow, bass. Flexible and powerful, it is a must-have for every enthusiast.
Details:
1. 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.
2. The board is powered by dual DC voltage. The car battery cannot be used as a single power supply. Amplifier boost power supply
3.
The power supply of the board is dual power supply, the audio input is 3 feet, the middle is the ground line, the two sides are connected together, any one foot is ok! If it is not the switching power supply,
If you use the ring cattle to supply power, and need to add a rectifier filter circuit!
If your switching power supply is not a dual output but a single output, and need two single power supplies in series.
4.
This board is mono channel for the finished board. If you need two channels, please buy two pieces.
5.
The power supply voltage is ±60---±85V for dual DC power supply. The lower the voltage, the lower the output power.
Specifications:
1. power supply voltage: dual DC power supply ± 80V
2. Maximum rated output power: 1700W (±80V power supply 2 ohm load, distortion 10%)
3. Efficiency: >=90%
4. Signal to noise ratio: 90dB
5. Total harmonic distortion: 1600W (±80 power supply 2 ohm speakers, distortion <1%)
800W (±80 power supply 4 ohm speakers, distortion <1%)
6. Frequency response range: 20Hz-22KHz
7. Speaker: 2-4Ω, pay special attention, if you need to get high power, please use 2 ohm speakers or use 2 4 ohm speakers in parallel. If you use 4 ohm speakers, the power is reduced by half and the maximum is 800W.
8. Voltage amplification: 50 times
9. Input sensitivity 1.2V (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 = 116x50x85mm
14. Weight: 350 g
The use of precautions:
1. The rated power supply voltage is ±80V for dual power supply, and the voltage can work normally at
±60 --- ±85V
. (
If it is a power frequency transformer, please leave a margin when the voltage fluctuates. The power supply is 3 power supply lines, positive and negative power supply. Do not pick up the wrong to avoid burning the board
)
2. Power supply is recommended for DC dual power supply ±80V filter better power supply
3. Speaker
recommended 10-25 inch 2 ohm-4 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 50 times. If the output power is not enough, add the preamplifier according to the specific situation.
