just asked the question really:) THANKYOU

erm. I believe the controller is 12v DC.

I think the problem you're facing is they usually come with a 110vac to 12vdc transformer. Just go out an get a 240vac to 12vdc. They're cheap and easy to find.

EDIT: Oh please tell me you weren't thinking about plugging 240vac into the power inputs on that controller board. You'll see sparks and waste a few hundred $ if you do.

Don't sweat it. It's stupid to plug it in without checking first. wink.gif

thanks mate - so I have just run out and bought a 240ac to 12 dc adaptor (that was easy - I have a shop next door).

It says on the side of the box to change a setting depending on if what you are plugging in is center negative or center positive. Any ideas?

just found the answer

"Yes, 12v, 5mm x 2.5mm barrel, center postive". well time to go home and see if if it has been damaged by its trip across th world:)

What's the amperage capacity on that supply you purchased? The controllers take a surprising amount of current.

It needs to be around 2A.

To little and it won't come on or it won't work properly. To much and nothing bad will happen. The device will pull as much power as it needs and thats all.

Yeah, like JJ says, just have a go. I had a little trouble and didn't want you to be pulling out your hair if it didn't seem to work. I should have been more specific when I asked the capacity of the power supply you had. Best of luck. Just give a shout if you have trouble.

Hi guys. So I got home and scowered the controller. NO POWER INPUT other then the pc like connector. No round barrel or anything like that sad.gif unless it is hiding somewhere! The supplied transformer says 120-260v ac so I assume it usable but no how to change it. It has one screw with 102 written on it and above it a symbol saying V+adj. Is this it. There is no idication of which way to turn it.

The net at home is down at mo and I'm at uni for 2 more hours so...hopefully someone is not in bed and can help me?

Dont know what I would do without you. Cheers!
