Hello

I bought this power supply for the 3-axis skulls, but not sure how to hook it up. Input: 85-250Vac Output: 5.1V/12A, 12V/2.5A, -12V/2.5A. It has a whole bunch of pins labeled V1 RTN V2 PF V4 V3 on the output.

Pins 1-3 +5.1V Pin 4-7 Return Pin 8,9 +12V Pin 11 NC Pin 13 -12V

Can someone translate this into layman terms?

I want to use this with the ssc32 board and don't want to hook something up backwards. I also want to be able to use some small lights and possibly some pneumatics and I have read you can connect the two 12V together to get 24V.

Thank you

Your power supply should have a "ground" pin. You should connect a black wire from this pin to the the "-" post on the "VL" connector of your SSC-32 board. Then, you want to hook a red wire from a 5.1v pin on your power supply to the "+" post on the "VL" connector of your SSC-32 board.

Finally, make sure that jumpers for VS1=VS2 are in place, and the jumper for VL=VS is in place.

This will let the single power supply power the board and all 32 servos.

Hello
Which pin? what is the return and the NC pins. There is a ground on the input I think. They are labeled L , N , and one that looks like an antenna.

The antenna one:

Is ground.

(hope that looks right in the post.)

RTN = Return = ground = Pins 4 through 7
5.1V = Pins 1 through 3
NC = No Connection
I am not sure what the PF is

Can you post a picture of the supply or a link to where you bought it?
And no, I don't believe you can hook the two 12V together to get 24v. I think it's the same output, it just gives you more than one place to connect to it.

If it were 2 separate batteries, you could do that, but even if it were 2 separate power supplies, it's not recommended to combine outputs like that.

I think the 24V thing will work. Test the 24V thing with a voltmeter. test from -12 with the black terminal and +12 with the red terminal and see if it reads 24V. The -12V terminal would now hook up as a ground on your prop and the +12V terminal will become your +24V terminal. but if you tie any of the 5V stuff into the same prop becarefull not to put the 5V RTN to the -12V (your +24V ground) or you will let the magic smoke out.

Sorry, I didn't notice that it had a minus 12V.

I stand corrected.

If you do not use the Ground wire and go between the -12V lead and the +12V lead, you should get the 24 VDC.

I misunderstood the info

This should be the input from your main power, usually from the wall. The L is the line current, the N is the neutral, and the "antenna" is the ground. It sounds like you will need a 3 pronged extension cord (usuall an outdoor version) that you would cut the end off (the end where you plug other things into). You will still need to plug into the wall. The wires inside the extension cord are usually black, white, and green. The black is the LINE (or HOT) and would attach to the L connection. The white is NEUTRAL and would attach to the N connection. The green is GROUND.

Hope this helps.

Hello
Thanks a bunch, folks. That really helps.
