hello alex,
sorry didnt see your reply, yes thats the box im trying to supply power to, but not sure how to tap of the power going to the controller box

Hi Ravi,

You need to connect that Power Supply you have to 230v AC - Mains Voltage.

Looking at the PSU you have the far right three terminals: Earth, Live, Neutral.

Get a common Kettle Plug (For a PC or a PC Monitor etc), cut end off and use it to power the PSU.

USUALLY - in a typical plug it is as follows:

Blue - Neutral
Brown - Live
Green / Yellow - Earth

If you want to be neat about it then you can get one of these: Click Me

That will you mean you can just plug it in and have it modular.

Once you have the PSU live, you just need to (I assume - I do not know what you have been supplied to control the spindle), power the PCB using 48v DC from the PSU using any of the remaining terminals. You have 3 sets of -V & +V on the left hand side of the PSU.
