I am new to Z Scale and I am trying to get my construction started
I have all the bits - and I have run up some items
But I am having problems with my transformers
I have two - electric05 and electric08 (6701/60402 and 37700)
One is 230V 5/60 Hz - the other 220V 50/60Hz
They seem to go OK and drive the train
But when I put a multimeter on the DC output they both read about 15.8V - almost double the 8V recommended.
I am wondering if the input voltage for New Zealand might be upsetting them?
Is there some way I can test furher
Is it expected that a mulimeter put across the DC would indicate double the voltage?
The AC reading is about right (possibly a little more than 10v
ANy help appreciated.

Hi Gordon
Did you perchance get those trafos from German eBay sellers? I've seen them listed and assumed that they must be more or less OK, at least for Europe. Given that the European input voltages would be almost the same as in both Oz and NZ they should theoretically be OK. I suppose it's possible that yours, being older units, aren't functioning as well as they used to and might be outputting a higher voltage than they're supposed to. But don't quote me on all this - what I know about electricity could be written in 72 point bold caps on a postage stamp!
The current trafo (pun not intended) for our voltage is the 67011. I've never tested what voltage mine output, but my trains seem to run OK and don't heat up. (ozman2009). |

Ozman They are indeed European. I believe that I am going to find out that what I am dealing with is the difference between peak voltage and RMS voltage? I found a thread at http://www.escala-z.com/t83-voltaje-trafo-marklin that I think I can relate to. PS recognise the ozman - I have some of your gear

Nominal voltage is 10 V, but it's unfiltered so the peak voltage would be 14.1 V. These are the voltages under full load and with nominal input voltage, so add a Volt or two while power supply is idle. |

Hi Gordon, and I recognised your name too. After yours and Tom's comments you should be OK with those trafos. Those two locos should be OK on your curves too.
I forgot to welcome you to the forum before, so I'll say welcome now. There's lots of good advice here. |

Ozman
Do you think you could put a multimeter across the DC track outlets with no load on the tracks and tell me what the multimeter says the DC voltage is.
Thanks

Sorry Gordon, but I don't have a multimeter. |
