I have one of these LED power supplies that provides 36v @ 3A and would like to somehow control the output brightness of the LED connected to it.
So I thought I can connect a simple PWM circuit between the power supply and the LED, but when I measure the ouput of the power supply it's 36v DC, and 64v AC between ground and (-) and 64v AC between ground and (+).
Is this a non-insulated power supply? Can PWM work with it?
