Description
This stereo audio amplifier board is capable of delivering high output power as 500W per channel into a 4Ohm load in 6’’ x 4.5’’ size based on Class D topology and Sure’s T-AMP technology, featuring high audio performance, low power consumption, high efficiency as 90%, flexible input sensitivity and ease of integration. All these features make this audio amplifier board applicable to home audio, DIY audio, loudspeakers, car audio and demanding industrial applications such as professional audio, broadcast system and alarm system. This audio module supports extremely wide power supply range as DC48V - 72V.
High Audio Performance
Benefit from dedicated PCB layout design, careful components selection and engineers’ attentive debugging, this high power audio amplifier board produces powerful and clean audio with high audio performance, whose SNR reaches up to 99dB and THD+N performs well as 0.03% @ 4Ohm, 10W, 1kHz. Therefore, this module can provide quite powerful, warm and clean sound.
Flexible Load Characteristics and Wide Load Range
This audio amplifier module features flexible load characteristics with optimization in the frequency response. It has been tested in the lab with capacitive loads, inductive loads and resistive loads to make sure its stability and performance. Due to its low output impedance, this audio amplifier board supports wide load range from 1.5Ohm to 16Ohm without impact by the loudspeakers load characteristics.
Disclaimer: Extra attention needs to be paid for any operation with purely capacitive and inductive loads. It is suggested to send an inquiry email to us to confirm system compatibility with us before you use it to drive such loads.
Input Sensitivity Customizable
The default input sensitivity of this module makes it a perfect match for regular audio sources like MP3 player, mobile phone and professional pre-amp. Meanwhile, the input sensitivity of this amplifier board can be customized in a very wide range which causes that the amplifier can always offer the best solution for diversified types of audio sources and players and this can be set by Sure before production.
Wide Power Supply Range
This high power audio amplifier board supports wide power supply range as DC48V – 72V. 48V switching power supply units are common used in industrial applications and it will be enough to evaluate our amplifiers. For amplifiers, higher input voltage means higher power. For those customers who require higher power, assorted boost converters and AC-DC power supply modules are also available in Sure Electronics then you can get the 2kW audio and
power solution without any difficulty. Sure Electronics can also provide 200V, 1000W power supply as matched solution for HPA series. Application customers can free up the development resources and greatly reduce the installation time and system cost.
Signal Level Sensor System
Signal level sensor system is equipped in this high power audio amplifier module for low power consumption. It will continuously monitor the input signal and there is a preset signal voltage threshold. When there is no signal (voltage is lower than the threshold) detected for a period of time, the amplifier board will enter into standby mode automatically, in which condition, it will consume lower power. When there is signal detected, it will go back to working mode immediately without miss of the audio.
High Reliability and Long Service Time
A low noise, cooling fan together with a robust heatsink is mounted atop the board to ensure sufficient heat dissipation and high stability. Full protection circuit, like over temperature protection, overcurrent protection, under voltage protection and high voltage reverse polarity protection, is equipped on this board for high reliability and long service time. Power and clip indicators are provided for a better overview of the running condition of the amplifier board.
Disclaimer
Please note that this audio amplifier is designed for audio applications. Please do not use it in non-audio applications. If you want amplifiers for non-audio applications, please contact with us. We will provide you with full set of audio solution with special optimization in specific requirements on frequency, protection or output voltage of different applications.
