s’il vous plais j’aimerais demander si c’est les 2 circuits qui sont 400W ou bien un seul. merci

Besides, in laying out PCB components of LED switching power supply, it is suggested that engineers should arrange the position of every functional circuit based on the procedure of the circuits. This kind of layout will will the signal flow more effectively and rapidly and make the signals maintain the same direction. In laying out PCB board, the first principle is to ensure routing rate; connection between the flying lines should also be paid special attention; components connected with wires should be put together. The size of loop should be reduced to the minimum extend to stop radiated disturbance of the switching power.
