Capable of producing 800W @ 1.5 Ohm, this mono Class D audio amplifier board employs Sure Electronics T-AMP technology. With high efficiency up to 94%, this board features low distortion and low noise level. The optimized heatsink design with a temperature-controlled fan provides enough cooling for most applications and eliminates your worry over heat dissipation. Fan works when the temperature of heatsink reaches up to 45 Celsius degree and stops when the temperature reduces down to 40 Celsius degree. Protection circuits to protect against over/under voltage, over current, short circuit and over temperature conditions are built in for years of enjoyment.
