Id it safe to try this power supply?

[Ashmore]

Hello all

So there I was happily listening to the extended jam on All Things Must Pass, about ten minutes in, when suddenly my Project Carbon spun down. Dead. Nothing else went off. It didn't trip the board.

I've checked the fuse in the TT and I 'looks' ok (I don't have another one handy). Nothing is hot, and I've left it for long enough to cool. But still nothing. The power supply is sealed, so I can't see if there's a problem there.

So, in lieu of any other options this evening I thought I'd try another power supply. BUT, I don't have one exactly the same. As I know nothing about numbers on electrical things, I thought I'd throw this out there and see if anyone can tell me whether this is safe to plug in, just to see if the power supply is at fault.

Here is where the numbers differ:

Project: input 1.0 A Output +15V, 1.6A
my other one: input 0.8A, Output +12V, 2A

Is it safe to plug in briefly?

Yep will be ok.

[Ashmore]

Super, thanks Ali

Working with the new plug.

So the inevitable question #2 is. Can I just leave my substitute plug on as a permanent replacement (I'm guessing if it was ok to try it's ok to keep, but thought I should check)?

As for the cause of the malfunction: I notice the little earth lead thing - the thin one with a spade - was unconnected. Presumably a little surge and that would do it in...??

It'll work but I'd advise getting the right one from Henley. the earth lead may have shorted something out

[Ali Tait]

Yep, get the correct one, or an equivalent.

Just buy a fuse?

[Ashmore]

OK chaps, I'll get the right one...

I would walpurgis, of course, but it seems to be completely enclosed with no obvious way to open it. It is 'possible' that I am being a dimwit, but on this occasion I think not.

[walpurgis]

Buy a cheap meter from eBay (£5) and check the output from the power supply. If that's OK, your problem lies elsewhere.

Simon, where exactly is the fuse you are referring to? Is there a detachable mains lead with the power supply (with fuse in the plug) or is it a plug top/wall wart type of supply?

I think it's likely that the power supply has just failed and if your alternative works without apparent performance loss I'd stick with it.

Cheers, Alan

Hi there Alan

It's a wallwart type, which I am now learning all about on wikipedia. No fuse (at least not one I can change). I'll just order myself a replacement adapter.

Thanks for all the responses.

Or you could take the opportunity and upgrade to a linear power supply. It will be more expensive though, but it may give you a small increase in performance.
