Note: The board needs dual DC power supply (3 lines, Baidu),and a single power supply is not enough! No way! No way! The power supply voltage is ± 55V~± 80V, which is too low to work and too high to burn the board. The maximum effective power of the board is 500W (under the condition of inputting 1V effective value under a ± 75V 4-ohm load)
Packing list:
