Information needed on new power supply

[IBBruin]

I received the g540, steppers and power supply today and it came with zero documentation. I was able to go to the web site and download the limited information available. I got answer's for my stepper questions but I still need additional information on the power supply. Please explain the purpose of the following terminal numbers 4, 5, 6, 7, 8 and 15

[KOC62]

Here is my guess.

Pins 4 & 5 are not used, hence no connection (N.C)
Pins 6, 7 are most likely used for romote on/off. If not used a jumper would be connected between pins 6 & 7.

Pins 8 & 15 are sense lines.
May be used in case there is too much voltage drop to your load. If you can drive a load without the use of Pins 8 & 15 then you don't need to connect anything to it.

You didn't say what power supply you were using so I couldn't look for it.

[edit: I didn't see the reply by KOC62 before posting]

My best guess:

4, 5 NC - means "not connected" or "no connection" (ignore those terminals)

6 R.C.G - Remote control terminal

7 R.C. - Remote control terminal

8 +S - remote positive voltage sensing terminal

15 -S - remote negative voltage sensing terminal

The remote control terminals are supposedly for adding a (low-voltage) switch to turn the supply on and off.

The sense terminals allow the voltage actually applied to the load to be regulated, instead of regulating the voltage at the power supply itself.

There is a discussion of those terminals at http://www.cnczone.com/forums/diy-cn...w_voltage.html along with a link to documentation, although the poster(s) reported difficulty in making the remote function work.

My suggestion would be to ignore all of those terminals for now.

In most P.Supplies with remote, the +S/-S has to be connected to the DC output +- respectively if not using the remote sense wiring.

Don't they typically come already jumpered?

I suppose that it depends on the particular supply and vendor.

Sorry, 48V 10A I was hoping the supplier would provide exact documentation so I posted in the supplier section of where I purchased it.

I could have done a better job in describing the supply so here it is.

[KOC62]

Your picture looks to me that all the necessary jumpers are attached. You provide the AC power and are ready to connect the 48V to your load.

That photo is indeed worth 1000 words.

The R.C. terminal is shorted to the R.C.G. terminal.

If you want to use a remote, low-voltage power switch, remove the jumper between those terminals and instead wire those terminals to a normally-open switch.

If you would like remote sensing of the voltage (at the load), remove the jumpers between the S+ and V+ terminals and between the S- and V- terminals, and then wire the S+ to the positive terminal at the load, and wire the S- terminal to the negative terminal at the load.

But, you should still be able to use it without changing any of those jumper settings.

.

The Hammond and the other linear regulated that I use do not come jumpered.

Only in Canada, eh?

I got all that hooked up, all I can say is WOW.

I've never seen my router move that fast in the last 8 or so years I've had it. I had to slow it down to 50 ipm's or it would run out of work surface before it got finished accelerating! I'll post a video in another thread. Anyone reading this and still fooling with the chinese junk, do yourself a favor and throw that junk as far as you can. I've wasted more $$ in materials than the price of my new electronic setup due to missed steps.

I guess WOW isn't all I had to say after all.
