Just thought I'd share this with you guys and girls in case anybody is in the market for a power supply to run their CNC mill conversion ?
http://www.ebay.co.uk/itm/181443785558 - this is an Eltek 1800si psu, originally designed for rack mounting but easy to connect to and there is data available on t'interweb showing which pins are which. Note these are used but tested with some load (not full load) originally I believe that these were used to charge backup battery systems on communications devices.
The output voltage is adjustable from the front panel. Internal construction is exceptionally good with quality electrolytic capacitors (Elna / Nichicon / Rubycon) - none of the junk that seems so prevalent in the Chinese psu's.
Please note that I am not the seller of these, but I've just bought one and tested it and it is absolutely fine. For the record, I have no connection whatsoever to the seller, other than being a happy customer. There are still two of these left up for grabs at £35 each (but worth a best offer)
Hope this helps someone.
Cheers
Robin

Bought one, thank you :)
Do you want to swap yours for a suitable linear PSU (toroidal transformer wired to capacitors etc)? Seems a waste to me to use such a nice PSU for a few stepper motors! If you're interested let me know - looks like we're not too far from each other, so shouldn't have to post.

Thanks Jonathan but I'll pass thanks. I agree that the Eltek is overkill for the job in hand but it will have loads of headroom and probably still be as efficient as a linear psu.
I am intrigued though by your comment Jazz - why would you feel that a linear psu would suit steppers more ?
Cheers
