Hmm, quick query for folks here.
Whats the current surge like on an smps when turned on? I ask as I want to use some kind of fairly subtle switch on my smps powered Fetzilla for turn on and it's only rated at 3A at 240V.
I know a 'normal' cap supply has quite the turn on surge, and I've always overspecced the switch accordingly (and used a thermistor to damp a class-a amps turn on surge) - in this case I have no idea, and no way to measure anything happening that fast.
I also appreciate a soft start module would also be a solution, but there's no space left in there...
Anyone using an smps able to measure the surge out there?

If you read all the previous things of the FetZilla you will read all you have to know regarding the on-off thump.
