I have sold the Titan transformers I used to use with my digital equipment. Is there any problem with using the pictured blue transformer connected to the central unit? I'd like to test some locos. Thank you.

Assuming the transformer is correct for your mains voltage there should be no problem using it to power your central unit. Use the L and O outputs.

I'm thinking of selling all my Marklin not that I have a huge amt. Those transformers went first. Been so long since I hooked up the digital equipment, I guess I forgot I needed a transformer.
Thank you everyone for your replies.

It is not recommended to use those transformers with newer digital loks on analog layouts as the reverse pulse can damage decoders. It is perfectly ok to use these transformers to power accessories or a 6021 using the non-variable voltage output. You should make sure that your model will provide an output that is acceptable for your digital setup as some electrical companies have changed their voltage which could result in either slightly less or slightly increased output from the transformers depending on what changes were implemented.

i.e. A transformer was designed to convert from 120 to 16VAC but will now render 14-15VAC if input has been dropped to 110-117VAC. Conversely, a transformer designed to convert 220 to 16VAC will render 18-20VAC if connected to mains now running at 240, which could damage your equipment.

The new transformers have been designed with these changes in mind and will perform better.

Going from analog to digital is not such a hassle as it seems ...

Hi Reed,

If you are only wanting to test some Loco's, either one really will work just fine as the power source for your Control 80.

The only real difference between the two is that 6667 is 16VA and 6627 is 30VA. If it was me, I'd go for using the 30VA for two reasons.

1: The Control 80 will draw some of the available current anyway so the higher rating will leave more for your loco's - although if testing one at a time, it really won't matter.

2: (Important).... The 30VA has a Red Light. Red Lights are pretty, and will go well with the red light on the Control 80. These small details make the difference between an event, and an experience.

Oh, and another plus... if nothing works, look at the pretty red light. If it's off, no point worrying about the loco Of course, it's entirely possible after a hard night on the turps that you are already seeing red lights everywhere, and if your Christmas tree is still up, that only complicates things.

Best.

Cookee.....

too much new year wine methinks.....

Ha ha, indeed, connect to the Central Unit, forgot that minor step because I have a Central Control which you power direct from the Trafo.

The 'floating' voltage is not as accurate as when it is under load, but a volt or three either way won't make much difference and can easily be influenced by the stability of your household supply.

Cheers
