I have a Digitrains 955574 Transformer which supplies my NCE 5 amp PowerPro. Unfortunately the transformer only has one 16v AC output but I now need two supplies; one for the PowerPro and the other to operate Peco PL 10 point motors. The DCC output from the booster won’t operate the points. The question is can I attach two separate cables to the one transformer output or must I obtain a second transformer?
I was getting very frustrated and cross yesterday; I tested the PL10 using a 9v battery and it worked fine but when I connected it via my 15 volt DCC bus  nothing, dead as a dodo. It would help me to regain my sanity if someone could tell me why that is. Thanks.

Hello Martin

Yes, you could attach a second pair of wires to the basic AC transformer.

You ask why it will not work direclty. The Peco PL10 is a solenoid. Its coil is only 4 ohms impedance so it is almost a "Dead short" on the DCC Power bus. At the instant it fires it draws MORE than the full 5 amps of the DCC Systems power so it shuts down instantly. Therefore you see it as "Nothing happens" because the DCC ststem is doing as it should and protecting itself..

In my opinion, the full "Best answer" is to obtain a proper regulated DC power supply for your NCE system (Much better for the long term health of your DCC system, because as well as having inbuild spike protection from the mains, it would also have proper output overload protection built in as well, unlike th AC supply which has NO protection at all) - then use the AC transformer ONLY for the points.

BTW do use reasonably large wire for your solenoids as they will need all the help they can get if far away from the power source.

Kind regards. Ahjay

Hello Ahjay
Thanks a lot for the very clear explanation.  Taking your advice re "proper regulated DC power supply"  I searched the internet with Google and one result was from DCCconcepts. However there is a significant difference between the price there and the price on your website. I have emailed you about this via your contact form as you may wish to remove it from Google.

Hi Martin,

Just following on from Ahjay's comments, how exactly are you wanting to control/operate these PECO point solenoids? e.g. totally separate and independent of your DCC system, or integrated?   i.e.  Are you just wanting to use basic momentary switch contacts for each point to set them in either position?

Certainly if you just Google "regulated DC power supply"  and even if you specify a current rating current and voltage, you will end up with a mass of confusing and probably conflicting hits....within a price range from $5 to $500 ðŸ˜®

Just for completeness - the difference in prices found by Martin is that Google has found a non-UK/EU price without VAT.
The website - if logged in from UK/EU shows VAT added.

Hi
following on from the above comments I have the NCE power Cab it has its own power source. The NCE unit works so much better when the power source is not shared. 
You can pick up a 16volt transformer fairly cheaply, make sure though it is from a reputable supplier.

Hello Martin - the price differential on Google is due to the search engine not including VAT in the reported price as we supply globally. The price you see on the website will be geographically correct (it will show VAT in the UK and EU, otherwise the price will be the same as that listed by Google). 
I hope this helps!

Thank you Richard.
m bryan and AHJAY have already explained the price difference due to the price I saw being ex VAT and meant for purchasers overseas. Perhaps the webpage should include ex VAT after the price?

Hi Martin,
If you live outside the EU, then the website displays the price without VAT and does state (ex VAT). Within the EU, the price on the website is listed as (inc.). 
I'm afraid that with our current system, I can't influence what Google displays as the product price. We will continue to explore avenues to remedy this but until then, the accurate RRP will always be displayed on the product web-page. 
Sorry I couldn't be of any more help.
