Hi, can you think of any Household consumer product, which is mains powered, and has an offline PSU in line with the mains cable, then another cable leading from the PSU to the product?
(We can only come up with laptops, there is literally nothing else?)
I own a toaster and a couple of hair dryers. I suspect that they aren't water tight. The toaster has a bunch of electronics in it for the timers, so it has some sort of power supply inside it.
It's not credible that regulations would ban such appliances.
It is credible that PSU manufacturers would make the smaller ones with no ventilation holes to avoid problems with dust and noise, and that they have accepted that the product is somewhat larger than it would be with fans and ventilation holes but, on balance, is more desirable to the end user.
Thanks, though for this post, the discussion is talking of offline PSUs for "Household consumer applicances".
These are not permitted to have vent holes in their enclosures.

#43 post....thanks, yes, EN61000-3-2 concerns harmonics.....other standards detail vents etc.
Actually we are wondering if the standards allows metal outer enclosyure offlien SMPS.
I think standard is EN62368, but dont really know, i have not payed the EU2.4 to go on EVS.EE and find out yet.
