auto transformer

I soon have a couple of cabs coming from u.s.a will this be good to use for them im pretty sure it is but dont want to make a mistake when they arrive.

thank you

It's not isolating, but it shouldn't matter. Would seem to be OK to run two 110V cabs on 220V.

depending on what cabinet ofcourse.

1000 watts max, so i think more than 2 cabinets under normal operation.

ofcourse its never good to stress this to the max, but i think 750 continue should not be a problem.

Two cabinets sounds very safe in this setup.

best thing to do is hook up a cabinet, and measure the real wattage drawn by it.

Best thing to do is simply look inside the cab if it's possible to switch the power supply from 115VAC to 230VAC and install a European wire & plug.

What cabs are you getting ?

Autotransformers have one drawback:
IF they fail they can pass the input (230VAC in this case) to the output. A cab that expects 115VAC won't like 230VAC.

True, it's a theoretical and not often happening risk but it does need to be mentioned.

This is another reason to try and switch the PSU inside the cab to 230VAC (Apart from being more practical anyway, no clumsy external box around your cabs).

From FrizzleFriend at KLOV:

Most 19" classic raster games come in at 100-120 watts. Most 19" vector games come in at closer to 200-220 watts. Most 25" raster games come in at about 150-160 watts. You can do the math from there.

i have a atari space duel coming i think the power setting can be changed from inside the cab (not played one since leaving atari in end of 1982 ) and centuri eagle (rip off moon cresta)

thanks will give it a read

Don't know about the Centuri but the Atari cabs of that era can all be set to 230VAC very easily.

You only need to switch a jumper connector on the power brick but since these are cabs from the U.S. the right jumper connector for 230VAc is probably not in the machine.

However, you can easily change the jumpers on the existing jumper connector. Then all you need is replace the U.S. mains cable and plug and done.

One tip: do clearly mark the connector that it's for 230Vac. The colors of the wires normally indicate what voltage the jumper connector is for so someone might get confused should you ever sell the cab in the future.

Oh one more thing: replace the mains fuse with one (about) half the value of the original.

Since voltage is double in Europe the current is half of that in the US.

thanks for the help

I'll see if I can find a picture of the modded plug....

[blackie63]

Any help appreciated getting it converted to uk power thanks

Going to have a look at this machines power supply do you have any idea how i can switch it to 230 vac ?

[level42]

OK, what color wires are the voltage selection plug. It's a plug with some very short wires going from one pin to the other (several) on it.

My guess is they will be yellow. There might be other plugs too, please let me know which color those (or that one) is/are.

In doubt, post a picture of the top of the power brick....

[level42]

Here's a picture of the schematics.

AFAIK this is the same for all Atari power bricks of this era, but I took the pic from the Space Duel manual.
