Hello,
I have an mosfet I drive with an arduino like in the schematic. the mosfet drives a led strip powered from a rectified 220v
for this mosfet I need to use a 12v VGS to turn it on, and an arduino to drive the optocoupler.
the arduino 5v the 12v are switching supply and powered from mains, like the rectifier.
separating the gnd for arduino and optocoupler form the 12v gnd and rectified 220v gnd provide an optical isolation?
is it safe in this configuration ?
thank you,
regards,
Cosmin
