En velment advarsel!<\/h1>\n\n\n\n

Jeroen Schrage (Facebookgruppen M\u00e4rklin H0\/00 analog AC modeltrain 1935-84 – https:\/\/www.facebook.com\/groups\/375034756440322<\/a>) har m\u00e5lt sp\u00e6ndingen p\u00e5 en moderne og en gammel M\u00e4rklin transformator. Digitaltog.dk har udvidet m\u00e5lingerne med flere andre M\u00e4rklin transformatorer.<\/p>\n\n\n\n

M\u00e5lingerne, som du kan se af fotodokumentationen, viser forskellen mellem en nyere analog transformator M\u00e4rklin 6647 og de gamle modeller , som blev bygget fra begyndelsen af \u200b\u200bhalvtredserne til 1980’erne. P\u00e5 det tidspunkt var den definerede sp\u00e6nding p\u00e5 elnettet i Europa 220V, hvor den er 230V eller endnu h\u00f8jere nu.<\/p>\n\n\n\n

Konklusionen er, at impulsen til retningsskift p\u00e5 de \u00e6ldre transformatorer h\u00f8jst sandsynligt vil kunne br\u00e6nde moderne dekodere af, og de \u00e6ldre type b\u00f8r under ingen omst\u00e6ndigheder anvendes sammen med digitale lokomotiver.<\/p>\n\n\n\n

Konklusionen er, at impulsen til retningsskift h\u00f8jst sandsynligt vil br\u00e6nde moderne dekodere af, og den \u00e6ldre type b\u00f8r undre ingen omst\u00e6ndigheder anvendes sammen med digitale lokomotiver.<\/p>\n\n\n\n

Det n\u00e6ste problem er jo s\u00e5 defekte transformatorer med kn\u00e6kkede eller smuldrende isoleringer og stik. Denne transformator k\u00f8bte jeg f.eks. p\u00e5 Facebook. B\u00e5de stik og ledning er defekt.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

P\u00e5 det sidste billede kan du se, hvordan Jeroen har tilf\u00f8jet en jordledning til 0270A. Tror det er det mindste du kan g\u00f8re for at forbedre sikkerheden.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Nogle dele af de gamle transformere er lavet af bakelit, som kan smuldre ned p\u00e5 grund af sin alder, hvilket for\u00e5rsager en kortslutning inde i transformeren (som ‘zinkpest’ p\u00e5 vores elskede gamle loko’er og tendere).<\/p>\n\n\n\n

Jeroens oprindelige tekst p\u00e5 engelsk:<\/p>\n\n\n\n

Sharing the risks on the use of old transformers, because one of our dear members made a warning, which I hereby seriously accept.<\/p>\n\n\n\n

From these photos you see the difference between the latest model analog transformers 6647 and the old model 0270A, which was built in the early fifties. By that time voltage on the net here in Europe was 220V, where it is 230V or even higher now. Both transformers connect to the same wall outlet.<\/p>\n\n\n\n

Output 6647:<\/p>\n\n\n\n

Max speed: 17,9V<\/p>\n\n\n\n

Reverse impulse: 25,7V<\/p>\n\n\n\n

Lights, turnouts and signals: 18,0V<\/p>\n\n\n\n

Output old model 0270A:<\/p>\n\n\n\n

Max speed: 19,0V<\/p>\n\n\n\n

Reverse impulse: 30,6V  <\/p>\n\n\n\n

Lights: 20,0V<\/p>\n\n\n\n

Turnouts and signals: 25,6V<\/p>\n\n\n\n

THE OLD MODEL WILL KILL ANY CONNECTED DIGITAL EQUIPMENT IMMEDIATELY<\/p>\n\n\n\n

SO MAY THIS BE A WARNING TO ALL OF YOU!!<\/p>\n\n\n\n

In the last picture you can see how I added a ground wire to the 0270A. Think this is the least you can do to improve safety.<\/p>\n\n\n\n

Some parts of the old transformers are made out of Bakelite, wich might crumble down due to it’s age, causing a short circuit inside the transformer (like ‘zinkpest’ on our beloved old loco’s and tenders).<\/p>\n\n\n\n
