Title: Switching Power Supply...
Post by: Moon Monkey on June 24, 2007, 04:19:40 pm
Hey Peeps...

I'm a bit of a noob when it comes to this though I've been trying to build a supergun for ages... finally dusted it all off after i managed to blow the last one up... :o last time i use an ATX power supply....

Got my hands on a second hand switching  supply of eBay... £12... (I'm in the uk btw...) but it came with no mains lead...

Any idea's how to hook it up? it's a Wei-Ya power supply and it has 2xAC, FG,2x +5v 15a, GND, -5v 1a, +12v 2.5a...... I know where the jamma side of things attach... but I don't know where i need to connect the mains lead... the uk has a 3 pin plug, ground, Live and Neutral.... any tips?

To start with this is just gonna be for my super gun but I'm planning to build a cabinet when I can afford to buy a house... always like the old cabaret cabinets (I think that's what you call em, the ones where you look down onto the monitor.. not a cocktail but a small cab one player...)

I may post some pics of the supergun but it aint anywhere near done....

Hold on hotshot....... first off, we are not "peeps", those are generally only found and eatin' at Easter time.  ;D

Second:
For a Supergun type setup all you really need is the AC (which is your power cord to the wall) with a power switch wired in and the +5,-5, +12 wired up to your JAMMA harness.
The EMI filter (AC line filter) is nice to have to help eliminate interferance, but the isolation transformer and distribution block is not neccisary for your setup.

The Bob Roberts site is a great read up on general information, that particular setup shown would be for a complete cabinet wiring job. Use what parts of it you actually need.

Thanks, Kevin ... I was over trying to organize the mess of links I have created in the restoration section of the wiki (and what a mess it is!).

No problem.... I understand..... I can't keep track of my own links let alone a wiki full.  :cheers:

Yeah, I would think it would be about that. (not sure what the actual US conversion is)
But it sounds about right for a new one.

so in effect i can hook to plug up to the power supply and then the power supply to everything else as needed? will need to get some terminals cause I'm sure just wires ain't good enough connections...

thanks for the help...

 ;D ;D ;D

Little bit higher, but not much-I picked mine up at the Betson warehouse (so no shipping charges) for $30US on sale, normally about $37. This was about 9 months ago.

hey moon monkey welcome to the forum,
get your backside down to maplins or halfords and buy some spade connectors,if you wire direct from the wall socket make sure you put a 3amp fuse in the mains plug
also double check the psu is switched to 240v on the voltage selector if has one(if you don't have a voltage selector then it will run on anything from 90 to 250v)
obviously you are now aware that the 2 ac connections are for live and neutral,fg is the earth

woohoo!!! an answer i was looking for!!! :notworthy: :notworthy: :notworthy:

I'm grateful for all the help everyone else has given but that's all i needed!!! any particular order for live and neutral? I've got a million and one PC/Kettle leads lying about so one of them will be sacrificed!! better get hunting out some 3 amp fuses and some wood for my joysticks!!! if only i could remember the pin out!!!

I also spotted somewhere about power switches, but that's on the bob roberts page....

it will be complete soon!!! This one will be the trial run... if it works I'll be making a better one that's better set out and not crammed into a tiny box!!! off to go solder my hands to the table!!! great 1000 miles rally here i come!!! :woot :woot :woot :woot

it don't matter which way round the live and neutral go to on the ac connections on the psu
to attain if you have a power switch look all around the psu to see if you have a sticker that has 110v/240v written on it
if you stick 240 in to a 110 setup you will have some very blown up components,so make sure you take the time to look
if its a 90-240v psu there will be sticker to state this(normally where the ac connects )
