Dimmers and humming Circuit Breakers

Farmboy


A couple of people have said they've had dimmers make their CB's hum. So what could be the cause and resolution, other than don't use dimmers?

    Agreed - IGBT trailing edge, or even PWM, are often far better than leading-edge phase control in terms of not causing "buzzing" or "humming" noises.


    I guess very soon, "smart" LED drivers (i.e. those with in-built power control capability) will be the order of the day, and we will forget we ever had these kinds of issues. Now, who remembers rheostat and leakage-reactance dimmers ?
