Description

Class D Amplifier 1x500W@1.5ohm - T-AMP

Sure Electronics - AA-AB31513

The AB31513 1x500W audio amplifier card uses Sure Electronics T-AMP technology, characterized by low distortion and low noise level. This amplifier board supports mono amplification using the PBTL topology. The fan works when the heat sink temperature reaches 45 degrees Celsius and stops when the temperature drops to 40 degrees Celsius.

Therefore the audible noise and the loss of inactive power carried by the fan could be omitted when the output RMS power is moderate.
