This board With perfect protection circuit.

The Power Transistor using New Original ON NJW0302G/NJW0281G.

Main electrolytic capacitor is using NOVER 10000uF/50V.

 

Works voltage: Dual AC 28---36V (For example AC 28V--0--28V or AC 0--28V 0--28V)

Output Max power: 150W+150W (Test under 35V AC 4ohm load. about 100W+100W at 8ohm load)

SNR: 108dB

Noise level: 0.2mV

PCB Size: 165*97mm

 

Quiescent current debugging:

Test the TP1. TP2 voltage as V1. V2 . Quiescent current = V1/0.22ohm

For example if you want the Quiescent current about 100mA. then Adjust the V1 about 22mV will be ok.

NOTE 2: We have DIY kit or Finished board (Optional)
