Buzzing noise from LED controller, even if it is set to off
Hi There!
I am getting very annoyed by my 12V system.
I bough the components what you can see in the image. Everything is working fine only that i can hear a buzzing noise from the controller when the LED is switched off.
When i switch it on, the sound Still remains in low light level, and at a higher level i can not hear that. I have red the topics and as far as i know There is a PWM module inside those controllers and in Low light it is normal to hear some buzzing.
My question is, why does it make the buzzing sound when it is completely off? Can some bad thing happen?
Thank you!
