WONDOM AA-AB33511Class D T-Amp Amplifier Module 2x300W + 1x500W 3 Ohm
This amplifier module from WONDOM is a powerful 3-channel module. It delivers up to 2x300W and 1x500W under 3 Ohm (THD+N = 10%). This module is based on Class D architecture and T-AMP technology, enabling 97% efficiency while maintaining high sound reproduction quality and low levels of noise and distortion. This multi-channel amplification PCB is therefore ideal for any DIY 2.1-channel audio system project.
The module accepts a power supply range from 24V to 50V DC via DC 5.5/2.5mm jack connector.
Wondom AA-AB33511: a high-performance amplifier module
The ingenious design of this PCB by Wondom enables it to achieve excellent performance levels, with SNR as high as 91dB and THD+N as low as 0.01% (3 Ohm, 10W, 1kHz).
Wondom AA-AB33511: efficient heat dissipation
This amplifier module features a low-noise fan and an optimized heatsink for optimum cooling of the module during operation. In addition, the module features a complete protection circuit against overheating and overcurrent.
Wondom AA-AB33511: a ready-to-use module
The module's mounting holes allow rapid installation in a case. The PCB features RCA inputs and screw terminals for plug-and-play operation, with no need for soldering.
