ciao a tutti,


while sorting out things in a drawer I have found this :





I think it's weird because it clearly says 110V but it also has an EU plug

I have searched the website but couldn't even find it as a model

anyone has ever seen it before ?

take care Alberto

Hi Alberto,

Sure, it's a 90-120V adapter/charger for countries using a "European plug".

More info here

IIRC a couple of years ago a part of Europe was still on 110V.

Ciao

Ciao, Alberto;

I have one almost like this (same AC IN connector) for more than 20 years, it came with a n 82143A bought in Europe (not by me...). The only two differences are:

1 - it reads 220V~ 50Hz (Germany?) and
2 - it is coded 82066B Eurocharger.

Ola Luiz,

what you have was the normal European type. IIRC, some 15 to 20 years ago they merged 220 VAC 50 Hz(continental Europe) and 240 VAC 50 Hz (UK) to 230 VAC 50 Hz with tolerances that everybody was happy. I do not remember, however, any larger European country with 110 or 120 VAC. But I will try to find out.

I remember that in the sixties, when I still was in Rome, we had both 110 VAC and 220 VAC in hour homes. A few years later only 220 VAC was left.

Of course you had to be careful where you put what... ;-)

Massimo

Some people have their equipments also fried after a wrong DC connection (capacitors usually blow away...). That´s why I prefer having a full-bridge, four-diode rectifier inside the equipment right after a low-voltage input connector. No matter polarity or even if it is AC, having the source enough amps and being it in the voltage range, all goes well.

Cheers.

Of which the HP 82240A/B Infrared Printer is a nice example.

Hi, Gerson;

to be honest, I had it in mind when I wrote that... You got it!

Cheers.

Ciao a tutti,

I'm from 1964 and I can't remember back in
the seventies

that we had in Milano 110 volts with that plug.
Well, I can't remember of any european country either.
I'll see my parents tonight for a pizza and I'll sure ask them.

I'll let you know

Ciao Alberto,
be careful: I mentioned Rome not Milan! A quick Google search confirms I am not (totally) mad... :-) AC in Rome...

I am just 4 years older than you and I only found this when I lived in Rome, during the sixties: I never found 110VAC in Milan since 1970.

Greetings,
Massimo

I asked my father last night

btw he worked at Enel the Italian Electrical Energy Company for a long time in the IT dept
which is where I have been using my first HP-25 just to tell where the story began

and as far as he can remember we had in Italy 115, than 125 then 220.

Anyway, the oldest model for which the charger is suitable is a Topcat unit,
which has been introducted at earliest in 1976, by that time in Italy the distribution was all at 220 ,
which lead me to say that the charger wasn't for Italy.

On the other side, that plug will not fit in all EU sockets, UK for example has a different one
the question we should find an answwer to is : which EU country had 110V back in 1976 ?

P.S. : Massimo remember to send me your email address for the boxes scans ...

Ciao,

I found a somewhat older website claiming different AC voltages for different Italian cities. Seems it was still worth mentioning in the nineties. No idea about the plugs, however.
