110 - 220 converter

[gyruss]

I got a quick question, I need a transformer to make my mrs Pacman cab (110volt) work on the european powersuply (220volt).
I have seen a couple of transformers which have different Watt volumes(?): 50, 100, 200 and 1000 watt.

Which one do I need? I just bought the 200 watt one, will this do?

[ckong]

yes.

[gyruss]

Great, thanks!

Isn't there a way to switch the original power supply to 220-240VAC ?

I know the Galaxian can so why wouldn't a (Ms.) Pac ?

[gyruss]

Thanks for the tip, I'll look it up in the manual and will let you guys know.

I already checked the manual. There is some doubt. The parts list mention a 115V transformer.

But the schematics show there is both a 220V and a 110V tab on the transformer.

Of course my Galaxian spent it's entire life in Holland so maybe they shipped it with another tranformer but I doubt it.

Have a look at the transformer on the bottom of the cab and see if there are some indications on the transformer tabs. A pic may help.  If there is a 220V tab, it's as simple as moving the wire that is now connected to the 110V tab to the 220V tab.
And of course cut off the US plug and install a European one.

Galaxian and Pac Man should be completely equal, Ms.Pac (and Galaga) is of course a little bit later and may differ, but from what I remember the power supply set-up is basically the same.

Damn, you're fast.
I'll check it tomorrow, and if it doesn't work thats oke because i've already ordered the transformer.
Thanks for your help, again!  

Btw I just checked your topic about using a tv as a monitor on Arcadecontrols.com, very interesting and usefull read!

will this one also do? 100 Watt?

I'd say that one is too small.
But as mentioned there probably is no need for them.

I hope to move in the Ms.Pac today (and move out the Meteor) so I can have a look at it.

if the machine is operating at max 100 it could work, but than again, you will be asking 100% of the capicity of the transformer and i suggest to take some over capacity, the 200W variant will be better i guess

even better , if there is a way to switch the power supply to 220 like Andre says you dont need a transformer

remember your pleiads, there was a switch jumper cable..



it could be that there is no jumpercable, but just more connections to the primairy side of the transformer

I hope for all the "new pacman / mrs pacman owners" that a switch option is there  

but i am sure Andre will find this out

Well, I _just_ brought back the Ms. (during a Feyenoord football match, I almost forgot about that, but it was _during_ so very quite near the storage location I was away again well before the end of the match (sadly they played 1-1).

Anyway, I just examined the transformer and we are out of luck (if you can actually say that when you own a Ms.Pac):
The transformer has a range of tabs, but the voltages are between 90V and 117VAC........so there is no way to switch this to 220V.

So this will either require a 220 to 110V transformer OR finding a transformer with the right secondary voltages (very hard to find) or a "Euro" Midway transformer. Also hard to find and shipping transformers is pretty costly because of the weight.

All in all, the step-down (220-110VAC) transformer is actually the best option in this case. I do suggest getting something above 150W.
I didn't find any power data (yet) on a Ms.Pac cab but the usual figure is around 120W so a 100W transformer is simply too low and having a little extra is a guarantee that the transformer won't be constantly running "on it's toes".

I will be building the extra transformer into the cab as I hate extra external transformers "floating" around. I may even still have an extra one around....Gyruss where did you buy yours and what did it cost ?

I will be building the extra transformer into the cab as I hate extra external transformers "floating" around.

that's what i'm planning on doing as well. usually there still a lot of space at the bottoms of cabs, so a step-down converter should fit in there easily!

I have a 200 W here, and i bought it in 2001 so it was still guilders

i belief it was 85 guilders at that time,

here they are selling simular, for 35€

http://www.allekabels.nl/Omvormer/1740/1075950/Omvormer-230V---110V,-200-Watt.html

the only difference in mine is that i can also turn it around (so input 110V and output 220V)

I use the BN100887 for my DK.

I bought this one:

€ 16.95 and i got it two days later, works great.
