Power supply query

[theotherphiljones]

Just got something from the states and it requires '15vdc, 1amp (1000ma), negative tip'. I've not come across this before. Anyone know of anywhere i can pick one up from? Or am i just having a wee case of 'lost in translation' with my yankee counterparts?

15V is unusual, but not outrageous; ditto the negative tip bit.

It *might* run quite happily on 12V - What is it?

'negative tip' refers to the wiring of the connector that plugs into your gadget. Unfortunately there's no official standard so they can be wired either way. A photo would help to identify the exact type of connector you need but meanwhile I'm guessing it's a 'barrel jack' like those shown in this link: http://www.maplin.co.uk/dc-power-plugs-43084

Unfortunately, they come in a couple of diameters and differing lengths.

If you can take your gadget along to somewhere like Maplins then they should be able to tell you exactly what connector you need. Alternatively, you could buy something like this: http://www.maplin.co.uk/ac-dc-multi-voltage-4a-switched-mode-power-supply-48517. It's far more power than you actually need but it's a pretty good price and one of the supplied connectors will probably fit - assuming you really need a barrel-jack of course.

With a bit more searching you should be able to find a cheaper 15v/1000mA, though you'll have to be sure of the exact connector type.

right ye are then. thats a bit of a bugger then! its the sound destruction device by graig markel. awesome sounding creation but unfortunately i didnt even bother thinking about power (like a noob). i guess i'll have to pop down maplins and ask those guys. cheers for the input guys

This goes to 15v, not sure of ampage though...

According to this, the Sound Destruction Device runs off a 9 volt battery:

That suggests to me that the external power supply is regulated down inside the unit. Most voltage regulators only need a couple of volts of 'headroom' to be effective so it might be that a 12 volt PSU would work. It certainly wouldn't hurt to try if you have one handy, but if you're buying a new one then you might aas well use get one with the specified voltage.

I couldn't determine the exact PSU connector type from this info so my previous suggestions stand. Though it might be worth sending an email to the company to ask them for the precise connector type.

Good luck with it though, looks like a great toy!

[/quote]Thanks for the recommendation. Unfortunately that's an AC rather than DC power supply so won't work for the OP. 15V is very difficult but, depending on the actual pedal, it may be fine at 12V or 18V. I would advise checking with the manufacturer of the pedal.
