HIFI Power IRS2092S 500W Mono Channel Digital Power Amplifier Board Class D Stage

Board use precautions to avoid burning: 1. Do not connect and touch the audio input terminal in the case of power. 2. The output is not empty. Connect the horn and do not short circuit. 3. To be used under the specified load and voltage; 4. Power amplifier 220V input interface completely isolated power supply is safe, please rest assured to use.

Circuit optimization, increase the horn relay protection, startup delay, shutdown instantaneous break, effectively solve the impact of the switch, with relay power supply, external 110V/220V AC can be; 10 years of product sound quality can not be said, welcome new and old customers to buy!

Board to double DC power supply (3 lines of that kind, do not understand Baidu) single power supply is not! No way! No way! Supply voltage ±45V ~ ± 70V, too low does not work, too high easy to burn board. Board maximum effective power 500W (at ± 65V 4 ohm load input 1V RMS)

Attention:

According to the power formula P=U*U/R= voltage * voltage/load, the power is determined by the voltage and load, high voltage, small load, the greater the power, the board power supply voltage range refers to the voltage board in this range can work normally, not all voltage and load power are labeled so high power output, for example, 12V power supply 4 European load, Maximum power 15W, maximum power 7.5W at 8 Ohm; 24V power supply 4 euros, power maximum 50W, 8 euros maximum 25W; At any time, the power of the power supply must be greater than the power of the power amplifier, otherwise the large volume will not move, the power will be reduced and interrupted, and the corresponding power output can not be reached.
