Details:
Work voltage:
AC24V-0-AC24V@3.9A
0-AC12V @1A
Transformer Power need about:200W
Out Power:80W+80W 8ohm
Size:140MM*96MM*65MM
With speaker protection
Use Note:
The board must be installed with a suitable radiator before it can work. The output voltage of the transformer must meet the requirements and must not exceed the range, otherwise it will cause irreversible damage to the power release board.
After the board is powered on, the red LED indicator begins to flash, and after about 10 seconds, the relay is turned on and enters the working state, at which time the LED is always on. Play the boot delay, to prevent the boot impact sound.
In case of abnormal operation of the power amplifier board, the relay will immediately cut off the speaker, and the red LED will flash at the same time, until the troubleshooting LED returns to normal light.
Note:
this is a diy Kit:all parts need buyer to solder it !
if need assembled board ,pls pay extra 8GBP !
