What do you think of this as a potential power supply replacement?

http://www.meanwell.com/search/rt-65/default.htm

I've read I should look for a power supply rated as follows: 5V@5A, 12V@2A, -12V@.1A

The Meanwell above is 5V@5A, 12V@2.8A, -12V@0.5A

I'm still learning, so any advice is appreciated.

Thanks!

So I bought an RT-65B and am wondering about the toroid between the AC inlet and the power switch.  I assume I should leave the component in place and not remove it.  Any thoughts?

Does anyone know the PSU harness color codes?  I assume the following:


pin:           Color:        O/P Voltage:     Usage:               Notes:
=============================================================
01                                                                                  unused
02             Orange        12v dc
03             Green          ground
04             Yellow          5v dc
05                                                                                  unused          
06             Purple        -12v dc
07             Orange        12v dc
08             Green          ground
09             Yellow          5v dc
10                                                                                  unused
11             Purple        -12v dc
12             Orange        12v dc
13             Green          ground
14             Yellow          5v dc

                 Blue
                 Brown

I make no claims that the information above is correct and anything you do with the information is at your own risk. Smiley

Well, it's a little early to say for sure, but the Meanwell appears to work.  Now on to a "diagnostics" issue.

That's very cool.

Could you post a picture maybe?

How did you wind up mounting the Meanwell in the Emax? It seems like the mountig holes dont line up -

  Ordered one...

I think I've wired something wrong - when I do a Voltage check, I'm getting 24V instead of 12V

this is the power supply I'm trying

http://034262c.netsolhost.com/wp-content/uploads/2011/06/SRW-65%20Specs.pdf

 Model 3002 - 5V 12V and -12V

  Here's where I'm confused, I assumed I could tie all the grounds to one connection, all the Orange wires to the 12V and all the purples to -12V - the old power supply had 14 connections, only 13 used, the new supply has 10 connections I'm assuming the ( - ) connections on the specs are the ground connections correct?

  So there are not enough individual outputs for everything - whereas the original had connections for each purple, orange and yellow and ground , the new supply has only 2 outputs for 5V (needs 3) 1 output for 12V (needs 3) and 1 connection for -12V (needs 2)

  Sorry, not wrapping my head around this, is this a no go?

help!
