Euro Power Supplies

Recommended Posts

I'm sure by now we've all seen and learned about the US power supplies that Atari used for the 8 bit machines (and that there is one that could damage your machine(s)).

 

That XL styled power supply looks awesome, wish they kept that design for the Euro one's too....but they don't exist I am sure.

 

Is there a comparable page/thread for European power supplies ?

 

If not, here are some pics of the one's I've got:

 

1) CO60592-11
Small unit for powering 400/800 or 1050.

Input: 220VAC, 50Hz 50W

T40/A

 

Output: 9VAC 30,6VA

 

Thermal fuse: 115 degr.C

Fuse: 5A

 

Made in Taiwan

 

English warning: WARNING Shock hazard Do not open

German warning: VORSICHT - nur zur Verwendung in geschlossenen räumen (= use only indoors)

 

Approval signs: GS (Geprüfte Sicherheit (="Tested Safety", German approval)

 

Notes: I did not open this one because I borrowed it and it's just a transformer, nothing more. Production date seems to be week 12 1987.

2) CO 61763-34

Larger epoxy sealed unit.

Input: 240VAC 50Hz 24W

Output: 5VDC 7.5VA

T40/E

No approval signs only text: Produced to BS415. BS does not mean Bull Shit but stands for British Standard :D

Seems to have a brand logo: TAD

 

Made in U.K.

 

 

Note:

I remember that one of these came with the 600XL I bought in 1983(84?). This is not that unit though. The mains plug is probably not original, I guess there used to be a UK mains plug on it and it got replaced with an aftermarket plug. The 240VAC indicates it was meant for the British market (but works fine here too. Present day, we officially all are at 230VAC all over Europe, incl. the UK).

 

Not repairable as it is fully closed and epoxied.

3) CO61763-11

Input: 220VAC 50Hz 26VA

Output: 5VDC 1,5A

 

Fuse: T 2.5A

 

Thermal fuse: 125 degr.C

T40/E

 

Approval signs: VDE (German) GS (Geprüfte Sicherheit (="tested safety", German)

 

Brand: FWGB which stands for Friwo Gerätebau GmbH. from Germany

 

Notes: The FW1599 Typenr. is a factory Friwo number. Although it doesn't say it was made in Germany it was produced by a German company and the unit is over a very very good quality. Construction, lay-out are excellent. I haven't checked the schematics, but the set-up is pretty extensive for a "simple" 5V DC power supply.

 

The big filter cap is of the Frako brand (www.frako.com), a very high quality German capacitor brand. FRAKO stands for FRAnkfurter KOndensatorenfabrik or "capacitor factory of Frankfurt". I couldn't see the brand of the smaller caps but I measured all of them with a high quality ESR meter and all show excellent values still.

I think this supply is the most common one for the XLs around here and my preferred power supply.

OK, so nobody gives a fuck....but has any of the Euro guys had a Euro power supply go bad, or even damaging the machines they were connected to ?

I seem to remember from BITD that sometimes the epoxied version sometimes blew it's thermal fuse and rendered it completely useless although I found them to get not that warm at all.

 

Especially compared to my cousin's C64 which had a power supply that you could fry eggs on. In fact his dad once installed a small fan on it. It was the first computer with a fan that I experienced and man, that was a joy....could barely hear that sucky SID because of it and I've hated any computer with fans ever since (one of the reasons to own Macs now instead of PCs.....but I think I'm drifting off :)

Thanks for your explanations. I have got a number 3 and I am a little surprised that Atari has actually produced a good power supply with quality parts. I did not expect this, certainly not after reading all the horror stories about failing power supplies.

Well they didnt build it themselves, simply ordered it from Friwo. Even so, indeed you'd expect them to have ordered them from a Far East company but I have a feeling that they had had bad experiences with the epoxied version so that's why I wonder if anyone here has had problems with those too.

 

There is something in my memory that there also was another version power supply for the 1050, I may have one of those still, will try to find it,

Hah, just googled and found it. This is the power supply that I got with my 1050 BITD. It's another FRIWO product. Clearly it was also delivered with the 1020 printer....this transformer is bigger than the 800 power supply but smaller than the XL supplies.

 

4) CO60592

 

Input: 220VAC 50Hz 50VA

Output: 9VAC 3A

FRIWO typernr.FW6699

Fuse T4A

Thermal fuse 117 degr.C

T40/E

Approval signs, VDE and GS (German) also Norway, Sweden and Finland.

Actually, I do. I still have three of the FW power supplies for the main unit, they are still good. This was excellent quality, and one of them nowadays serves as experimental "lab" supply for TTL circuit expeirments on a bread-board. It is very stable and survives short-cuts without problem.

The FW disk transformers were not so good - I saw two of them dying. It was usually the termal fuse that blew after extensive use, for example when playing "seven cities of gold" for a day or so. They tend to overheat and were a bit underpowered for extensive use. You could simply "repair" them, though: Open the unit, and bridge the fuse. (Outch!).

 

You are right with the C64 power supply, though. It was not very stable. After extensive use, the voltage broke down and you were no longer able to turn on the C64 because power was not stable enough.

Ah, so that might be the story I remembered....you mean bridging the Thermal fuse I assume ?

 

You'd expect the Friwo 1050 PSU to be more capable than the Taiwanese one (nr. 1) though because the Taiwanese is only rated at 30,6VA and the Friwo at 50VA.

Again, I never had any problems with any Atari PSU's so far but I don't remember playing seven cities for very long ;) I do remember very long "back-up" -sessions at regional clubs though ;) ;)

Those poor Aussies got some very weird and ugly PSU's by the way. These I found with a (finished) e-bay ad:

 

 

Not sure if these were official Atari supplies, but at least they were specially made for the XL and 1050.... Note that the 1050 supply can handle 2 drives which is pretty handy.

Yes, exactly that. Ehem, not to be recommended, though. Problem might have been that over time the loss in the voltage doubler in the 1050 increased, because the caps got bad, the diodes aged and the motor aged, too. Thus, I assume that at a certain age, it was more than the unit could take.

My PAL 800/810 came with another type of Power supply with (as far as i recall) a blue lacquered finish on the bottom. Will take a pic the next time I get it out of the box.

I'd be interested to know if there is a good replacement for the 800/810/1050 AC/AC power supply for 230V? I can't seem to find anything with the right specs on the usual electronics sites.

Very expensive ones (there's a thread on this issue in the ABBUC forum right now, 46 Euros were mentioned). As Sleepy also mentioned in the ABBUC forum, there was one by Maplin (UK) that worked fine after replacing the PSU plug and adding an internal fuse (UK PSUs have their fuse inside the plug) or using a mechanical adaptor - this one seems to be sold out though.

I've been looking at the schematics of the 1050 and I THINK you should actually be able to use a DC supply on it. The power supply section of the 1050 is extremely standard (the one's we got taught at school). I'll have to have a closer look at it when I return from work but I believe you should be able to use an (unregulated)DC power supply on it providing it delivers the right DC voltage and the plus is on the inner pin.

 

Don't go trying anything just yet though.....I'll do the theory and give it a try before you guys blow up stuff instead of me :)

Mmmm, I think the voltage doubler is making the idea I had impossible.... :(

 

I found a guy selling lots of Atari PSU's from Poland and they are from the late XE era:

 

5) CO 700045-01/T

Looks to be epoxy sealed, not sure but I can't see any screws or open vents.

Input: 220VAC 50Hz 18VA

Output: 5VDC 1A (so little ?!?!?)

T40/E

GS approval logo.

Brand: Magpower Manufacturers PTE LTD.

Made in Singapore

Date: 4-88

I love the German name of the product: Stromversorgungsgerät. Direct translation would be "Current providing device" :)

Translated German text on lower half:

For connection to a Micro-Computer. Turn device off before connecting. The mains cord of this device cannot be replaced. If mains cord is damaged do not continue using device.

It looks he has plenty of them judging by the boxes :)

Following a hint on the ABBUC forum I bought these . They look similar but have 2.1 amps and the connector seems to fit. (Didn't have a setup to test them thoroughly, the red light on my 400 went on but I did no further testing.

Good price and higher amps rating, always good. Well, it's not that critical, as long as it's about 9VAC is will work just fine.

Nice that it has the right connector, I'm not 100% sure about that on the one I pointed to on ebay.

 

The seller you mention only has 6 left so if guys are in need get them while you can :)

I'm UK based and have MANY type 5 PSU's supplied with UK systems - seems to have been pretty common in the late 80's.

 

I also have the MAPLIN branded 9V perihpheral PSU's that were shipped with my 810 drives back in the early 80's (bought from Maplin).

 

I have examples of several others mentioned, but lots have failed - so my question is does anyone use modern replacement PSU's in the UK and if so what make/model?

I purchased a bunch of Maplin's L53BR PSU's some years back and Sleepy modded them (Euro plugs and internal fuse)., but these are no longer available. They also cost me 10 quid less than their price tag on the website today.
