I'm looking for a transformer that will work with my LGB 51070 Controller, LGB aren't very specific what transformer to use but it says use a LGB 50110. So if anyone knows of any for sale I'm looking for one, or something similar :)

According to their site they quote 18V ac 5.5A output for the 50110.
So a 230v to !8v transformer rated at 100 VA or more will be fine here in the U.K.

Yep you're correct, I found the manual for the controller and it says to use a LGB 10110.. They seem hard to come by, or stupidly priced on some websites.

That will certainly do the job..

Depending how fast you really want to run, and how many loco's etc. you want to run at once, You may well be able to use the smaller 15V AC unit?

But the bigger one will probably do you 'forever'..
Well I noticed the 15V AC Unit was 3A, but the controller is 5A. So I wasn't sure if it'd be sufficient.

Depends what you run, and how many you run at once..
For (most) people, running DC, they will only run a couple of loco's at once. As long as they are not both Mogul's, 'Orient' sets, or big American outline diesels, then the smaller unit will cope, and the 15V upper limit will not be restrictive to top-speed.

You may, in the great scheme of things, need to run a separate supply for accessories, building lighting etc. Though I would suggest this is a good thing, as a fault in the 'accessories, will not stop you running trains.

But like storage :) if you can stretch the budget to the larger unit, it will serve you well, and may be the only transformer you will need to buy?

Well I do have a Mogul and a SVR Mallet.. But they seemed to run fine on 1A.. I'll take my chances and get the 15V one, I'm sure it'll be better then what I have.

Since the 51070 can use 18 volts AC or up to 24 volts DC input, I would just find a discarded laptop power siupply. I have found many DELL 19 volt 4.3 amp DC supplies. Also here in the USA there are 6.5 amp 24 volt dc supplies for under $30 US. Check out MPJA.com.

This may or may not be a concern. I think the original 5007 controllers I have relied on the the transformer to shutdown in case of a short circuit. This limited the current flow through the controller thus keeping it from being fried. Allowing up to 10A could be a problem. This may not be a problem with the newer 51070. In any case, what you bought should be fine.

Edit - You can safely ignore this. The 2014 Catalog states the 51070 has built-in "Short circuit protection"

So the DCC Supplies transformer works the 51070 fine it would appear, the speed seems fine even though it’s outputting 15v ( I did only test it on a 3ft length of track)

Although saying this I have been offered the 50110 so I think I’ll get it then I know it’s actually designed to work with the controller.. I’ll see how it performs on the big railway outside this weekend.

Those little transformers are a reassuringly heavy lump of German Engineering!

I am always surprised, just how heavy it is! :think::nod::nod:
