Being a family member of Mid Power Stereo Series, this stereo amplifier board is capable of delivering 30W per channel into 8 Ohm load. It employs TI' TPA3118 Amplifier IC to achieve high efficiency. The module dissipates only 0.72W with no signal when in ON mode (around 0.07W when in stand-by mode). Excellent heat dissipation eliminates the requirement of an extra heatsink and increases its reliability. Over current protection and over temperature protection are included to extend the longevity of the amplifier board.
