Description

Class D amplifier 1x750W @ 4ohm - MOSFET IRFB4227

Sure Electronics - AA-AB31431

This audio amplifier board uses the IR high voltage IR, IRS2092SPBF class D high performance audio amplifier driver and IRFB4227 single channel 200F HFETFET power MOSFET. This amplifier board supports mono amplification using the half-bridge, one-channel topology.

Thanks to the dedicated heat sink design with temperature controlled fan, it is able to deliver the maximum power 750W RMS @ 4ohm without extraordinary heat sink. In addition to the integrated protection of the chip, the protection components against ESD discharges and used throughout the input and output of the amplifier board guarantee its robustness and reliability.
