AA-AB31431 -1 x 750W @4ohm - MOSFET IRFB4227 - Amplificatore in classe D - Sure Electronics

Brands Sure Electronics
Chips IRFB4227
Output Power [Watt] 750Watt
Channel 1

 

Overview:

This audio amplifier board employs IR's High Voltage, high performance class D audio amplifier driver IRS2092SPBF and 200V Single N-Channel HEXFET Power MOSFET IRFB4227.
This amplifier board supports mono amplification by using one channel half bridge topology.
By means of dedicated heatsink design with temperature controlled fan,it is capable of delivering 
maximum power 750W RMS @ 4ohm without extraordinary heatsink.
Besides of built-in chip protection, ESD and spike protection components used throughout input and output of the amplifier board ensure its robustness and reliability.
