joefr would you like to show your oscilograms of rele working or any oscillograms from this device ??
Here are the two oscilograms
This is oscillogram with scope probes across rellay drive coil:
This is oscillogram with scope probes across flyback primary coil
Scope probes are connected to drain an source of IRFP540 drive mosfet.
It is hard to get nice scope shot because of the RF interference.
