Hello, I have a problem with a squeaking LED strip power supply. I have a 200w 16.5A power supply, radio controller with remote control. I have a 20mb tape connected, several sections on separate cables. After adding another 3.5mb, the power supply starts beeping. When I set the color to green, blue or red and the brightness is at maximum, the power supply does not beep. In other color and dimming configurations it squeaks. Where is the cause seeker?
