Assembled UPC1342V + NJW0302G/NJW0281G Stereo Power amplifier board + heatsink
Note: This is a assembeld board with heatsink
PCB Size: 165*97mm
Heatsink size:170*40*60mm (W*D*H) heatsink about 0.3kg/pcs
AMP board works voltage:Dual AC24-36V (for example AC28V-0-AC28V or 0-AC28V 0-AC28V)
Output Power Max 150W+150W (test under 35V AC 4ohm load. about 100W +100W at 8ohm load)
Signal to noise ratio: 108dB
noise level: 0.2mV
This board With perfect protection circuit.
The Power Transistor using New Original ON NJW0302G/NJW0281G.
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.
this assembeld the default Quiescent current about 100ma. if you need adjust higher. will need change biger heatsink.
