Description
This is a mono Class D audio amplifier board with mid output power as 200W into a 3Ohm load based on Class D topology and Sure’s T-AMP technology, featuring low distortion and high efficiency up to 93%. Easy installation, high audio performance and mid-power output makes this audio amplifier board suitable for home audio, DIY audio, desktop audio, game machine audio, kiosk audio and other demanding industrial applications. A DC15V – 36V power supply is required.
High Quality Audio Performance
By means of dedicated PCB layout design and engineers’ attentive debugging, this low power audio amplifier board features high audio performance, whose SNR reaches up to 101dB and THD+N performs well as 0.0051% @ 3Ohm, 1W, 1kHz. Output noise level is only 129uV at the condition of outputting 150W @ 3Ohm, THD+N 1%.
High Reliability and Long Service Time
An optimized heatsink is mounted atop the board for better heat dissipation, which improves its reliability even if in rough working environment. Full protection circuit, like over temperature protection and overcurrent protection, is equipped on this board for high reliability and long service time.
Easy for Installation
Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. Thanks to the pre-mounted industrial terminal interfaces, all you need to do is to plug in cables and enjoy music, without any demand of soldering, which is swift and convenient. If you want all the interfaces, please contact us. MOQ would be required. Power and clip indicators are provided on board to give you indications of the overall condition of this amplifier board. This board supports shutdown function, you can simply control your audio system.
