Aye, I know ;) Actually as it's in an extension lead at the moment I just inserted the (plastic) earth pin on the schucko->UK adapter and then pulled it back out again. Fnarr..

Or get a good old-fashioned linear one, as it's hardly a critical application.

They seem harder to find these days than switched mode supplies - although enough digging on the Maplin website did throw one up that doesn't say it's switched mode, so there is hope! ;D  Ta though - I have a bunch of PSUs lying around from various things now defunct (like monitors) and one of those will probably fit the bill for free so it's worth a stab  :y

Ah.....You're a big softy at heart, Aaron.  ;D ;D ;D

I hope that Tiddles and co appreciate what you've done for them. ;)

I'll do anything for furballs ;) They gained a whole bunch of new stuff yesterday - a ball constrained to a 'track' that flashes when they knock it around, a kind of face massage post thing, scratching post with beds, water fountain .. double sealed litter bin so the kitchen doesn't smell like cat crap anymore ;D ;D

Although they are still corralled into a makeshift 'room' we've built for them overnight - then again, we keep making the 'walls' higher and every morning they've either grown enough to jump over, or figured out what they need to push toward the wall to get a high enough vantage point to make it out ;D Oddly enough they only start doing that when we get up - overnight they're happy to be contained with their beds, food, etc etc.

Easier ... and in £'s ..  :)

That's basically what it was supplied with ;) Only it's so appallingly badly manufactured that it only makes a good connection if you stand there holding it ;D

Annoyingly my folks used to have a whole bunch of old German extension leads with UK plugs on the end from our time stationed in Germany .. right up until they moved house on Tuesday and threw all that kind of stuff out  :-X :-X ;D

Water fountain  ??? ???

A small word of caution - will almost certainly be ok anyway .....

Any item sold would only have it's type approval using the power supply provided by the manufacturer - so you probably need to be aware of that.

Insurers could get funny IF there was a problem as a consequence - so probably worth being a bit careful and unplugging if going out/at night etc.

I'm a bit of a Luddite regarding power supplies - I prefer a transformer at any time  ::)

Agreed about the approval, but, given that it wasn't even supplied with a proper UK mains plug, I'm guessing that's a dodgy area with this product to begin with. I'd rather have it powered by a properly compliant UK mains adaptor. Assuming that's what Maplin are selling. :-X

As to the type of supply - a cheap and nasty transformer is just as likely to burn the place down as a cheap and nasty SMPS. Granted, it won't create as much radio interference during its' short life, and, for that reason alone, I agree with you. ;)

Type approval relates to mains powered items only and hence only the adaptor would be considered part of it as the 'fountain' is a LV appliance.

Given the source and mains plug fitted, the alternative power source could be considered an upgrade.

This is exactly why in the telecoms kit design industry I used to be in, we never touched mains, we either bought in an approved closed frame supply or an external approved wall wart

Poundland and 99p shops will supply 13A to yank 2-pin adaptors for £1 and 99p respectively.

Make a short extension lead using 3 core 1.5mm² flex, a rubberised trailing socket, and a standard 13A plug (preferably MK), job done!

If you decide to go the SMPSU route, allow for a 50% derating.
