Description

This mono amplifier board is capable of delivering 500W into 4 Ohm load. This amplifier board supports mono amplification by using one channel half bridge topology. It integrates IR's High Voltage, high performance class D audio amplifier driver The chip IRS2092 and 200V Single N-Channel HEXFET Power MOSFET IRFB4227 to deliver high efficiency up to 93%. The optimized heatsink design with a temperature-controlled fan provides enough cooling for most applications and eliminates your worry over heat dissipation. Over temperature protection and over current protection increase its reliability.
