LED current setting

Dear all,

     In pattern sequence, I can display the patterns with red,green,blue,R+G,R+B and G+B.The problem is that I can't play them with white.The pattern flashed once ,got dark ,and stopped at the first pattern  ,then Pattern Sequence would change to Video Mode by itself.

     Is it the problem of LED current?When it was set white,all LEDs were on.The LED current  values :

       R:104

       G:135

       B:130

     What can I do to display white patterns as other colors?

Thanks ,

Liu

    Hello Liu,

    It sounds like your power supply cannot handle that amount of current draw from the LED drivers when all three are on at once. That amount of current is probably causing a voltage drop which resets the LightCrafter 4500. Try using a higher wattage power supply.

    Best regards,
