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.

I'm really tired today just travelled 1500 miles but looking at it Earth, live & neutral to the mains and you have 3 positive rails and 3 negative rails for the DC out.

e2a alex beat me to it with a better explanation lol do what he said.

Thank you very much lads for the help, so on the back of the bottom enclosure box I have 3 pins which a kettle like cable plug into:


This currently is plugged into the power supply box for my controller, can I just taop into these 3 pins and then wire some more wires to the spindle controller l, n and gnd?

I imagine that would be fine, can't see it drawing more Amps than that plug is designed for.

Can't see the amp rating for the IEC socket but looks like it should be fine anything over 10amp is in the zone. If it wasn't for some reason you can buy a new higher rated socket very easily on ebay for <£3 but the size of those pins I'm sure that's 10amp minimum.

A good place to skank these sockets is old PC power supplies for pikeys like me ;)

Again thank you very much lads, will probably have a go at finishing this wiring tomorrow night and report back :-)

[ravihotwok]

one last question,

what wires go where from the power supply box to the spindle pcb?
