Description

Class D 1x500W @ 3ohm amplifier - T-AMP

Sure Electronics - AA-AB31511

Here comes the 1 x 500W amplifier board, AA-AB31511. This audio amplifier board uses the T-AMP Sure Electronics - STA516BE technology, characterized by low distortion and low noise level. This amplifier board supports mono amplification using the PBTL topology.

Thanks to the dedicated heat sink design with temperature control fan, it is able to supply a maximum power to a 500 W RMS @ 3ohm channel without extraordinary heat sink. In addition to the integrated protection of the chip, the ESD protection components used in the entire input and output of the amplifier board guarantee its robustness and reliability. Recommended power supply: ALC24V6AJ.
