Seeking SMPS for AC/DC, 240V, 24V, 25W+, IP65, Metal enclosure

Hi,

SMPS sounds like you want the output to be DC. Please confirm.

An IP65 metal box makes sense.
You need to get rid of the dissipated heat. And an IP65 cable outlet.

Tell us the whole story.

Thanks yes, DC is required. The whole story is pretty well as above , and its for outdoors.
How easy is it to make an IP65 cable outlet? Just a waterproof cable gland?

The philips outdoor Xytanium range of SMPS seems to have vanished?

What about putting one of these into a really wafer thin walled plastic enclosure (cheaper than metal) and using that.....?

..having really thin plastic walls would mean that there would be still good thermal dissipation. If the plastic wall got breached, then the product is still inside an earthed enclosure, so safety standards couldnt complain?

Mind you, not impressed that the LCW25 offers no way of calculating the lifetime of the electrolytic capacitors in it....and the datasheet gives no product lifetime.....so you have to take it that the product lifetime is 3 years (warantee) at 40degc and max power, continuously?

We could put one of these into a metal box...
....but then the box woudl have to be earthed, and the SMPS woudl be bound to then fail common mode emissions when it is placed into an earthed metal enclosure......then again.....i suppose we just add an up front common mode choke and y caps to chassis.....it needs a mounting pcb anyway...to take the MOV and fuse.

...or even one of these...
...lets you pick your own electrolytic capacitors....and £2....also easy to copy and do your self if they go nil stock

...woops, that was only 3W..the mouser search engine didnt eliminate it out.

Also, as has already been agreed previously on this forum...no offline SMPS (non fully-resonant) can ever pass radiated emissions unless its in a metal enclosure (may be metal grill). So buying a IP65 plastic SMPS is a waste of time.

Here is a good one...metal case an IP67, but no price for it anywhere

...and no Power supply company (XP, TDK, Mornsun, Meanwell etc etc) allows sorting their units on IP rating
