Sir TophamHatt Posted June 15, 2020 Share Posted June 15, 2020 (edited) How much power comes from the extra bits on the end of a Hornby power controller: Is it AC or DC? Cheers! Edited June 15, 2020 by Sir TophamHatt Link to post Share on other sites More sharing options...
giz Posted June 15, 2020 Share Posted June 15, 2020 According to what its says on the unit, there is one 0 to 12v dc output, presumably the one on the right, and one 16v AC output, I'm guessing on the left. The input is also 16v AC, from a separate transformer. Link to post Share on other sites More sharing options...
smokebox Posted June 15, 2020 Share Posted June 15, 2020 (edited) It's controlled dc on the wires that go to the track. The two screw terminals supply fifteen or sixteen volts ac, uncontrolled. Edited June 15, 2020 by smokebox Link to post Share on other sites More sharing options...
Sir TophamHatt Posted June 15, 2020 Author Share Posted June 15, 2020 (edited) Hmm. Two conflicting answers. I'll just wait until the control boards arrive to do what I want as this should be regulated 12v output. Unless I use the more modern Hornby controller? I thought they were all around 16v outputs though? Edited June 15, 2020 by Sir TophamHatt Link to post Share on other sites More sharing options...
Toton Posted June 15, 2020 Share Posted June 15, 2020 They're both right although giz openly admits he doesn't know the layout of the unit, hence your confusion. The 0-12V DC controlled output to the track is via the cable wrapped around the unit. The uncontrolled 16V AC is via the screw terminals. Sorry if this is teaching you to suck eggs but the symbols next to the volts indicate the type of current. ~ is AC and the combined solid line and dashed line symbol means DC. I couldn't tell you the 'power' without the current rating which isn't shown in the picture. Not sure if power is actually what you're interested in, though? For others info, the socket on the left is the input. 1 Link to post Share on other sites More sharing options...

giz Posted June 16, 2020 Share Posted June 16, 2020 17 minutes ago, Crosland said: So where's the input? Looking at images online, there is a 16V AC coaxial input socket at the left hand end, controlled DC to the track via the lead and the screw terminals on the right are 16V AC out. What threw me is every dc controller I've ever had (e.g. H & M) used screw terminals for the controlled DC output. The OPs comment about needing a regulated 12v output is a bit concerning, I don't think this unit will provide that. Link to post Share on other sites More sharing options...

RMweb Premium kevinlms Posted June 16, 2020 RMweb Premium Share Posted June 16, 2020 The overall power is the key to these entry level units. If a certain amount of power is being used to run the train, then it is NOT available for other devices. Look at the separate power supply and find the ratings of that. This will provide the overall power available in total. Link to post Share on other sites More sharing options...
DCB Posted June 20, 2020 Share Posted June 20, 2020 It's designed to be used with a specific transformer, presumably a wall wart. It makes an awful lot of sense to use the correct transformer with the correct overload protection. If in doubt a 1/2 amp or 1 amp polyfuse won't dent the bank balance unduly. 1 Link to post Share on other sites More sharing options...
