Mod3 Posted September 23, 2012 Share Posted September 23, 2012 Hi Fireengine and welcome to the forum. I've moved this topic into the signalling area where you are likely to get more response, I've also edited the title for you - a lot of members here use the "View New Content" button to see whats been added to the forum, and with that they only see the titles of posts, so it's worthwhile ensuring the title contains enough information to atrract a response. It's worthwhile using the search and entering traintronics as these signals have been discussed several times. cheers, #3 Link to post Share on other sites More sharing options...
Suzie Posted September 23, 2012 Share Posted September 23, 2012 Traintronics signals run at 12V DC, and are common cathode. Don't use a transformer, they are AC, just get yourself a simple 12VDC power supply (Maplin N93JU or similar) and connect the negative to the common terminal, and switch the positive to control the aspects. A 1A supply will be enough to do forty or so signals, get a bigger one if you have more. Link to post Share on other sites More sharing options...
RMweb Gold RFS Posted September 23, 2012 RMweb Gold Share Posted September 23, 2012 I used an old Netgear router power supply that I no longer needed. It's rated 12V DC at one amp and has been powering my signals for some time. Link to post Share on other sites More sharing options...
