| 790037 | 2009-07-09 22:28:00 | You might have to bite the bullet and buy an american inverter. The good news is one is on TradeMe! www.trademe.co.nz Feed 12V into that and you get american power out. It might just solve your problems. I would suggest trying to negotiate a better price on that one though as the demand here is probably non-existant.My heart jumped when I saw that - but I think it is not going to do the job, as 12v doesn't figure in our scenario. The voltage to the track is 18v, and the input to the controller is 110v. |

Ends up as a rather 'circuitous' power supply in the end :groan:So are you suggesting the 12v car battery is the principal power supply? So the scheme would be: 12 car battery -> inverter ->110v/60hz -> train controller -> 18v -> choo choos. Have I got that right? |

| 790040 | 2009-07-09 23:52:00 | Looks right, but I have no knowledge of train controllers. Anyone? | seltsam (13470) | ||
| 790041 | 2009-07-09 23:57:00 | Unless an inverter is built for pure sine wave output (most are probably not) then the dirty waveforms may possibly cause problems on such seemingly sensitive circuitry.... The one I linked to is. I agree that a modified sinewave inverter would probably cause even more problems! However, Tony, a car battery need not come in the equation. I'm just suggesting running the 12V input of the inverter from an approprately rated 240-12 power supply (Jaycar sells one that will do 8A, ie 96W, for a bit under $50). Then you get 60Hz 110V power out. If you have the original american transformer for the train (or the train controller accepts 110V) you could simply use that. If not, you might also need a 110-230 step-up transformer which can be found easily. It is roundabout indeed, but there's no non-roundabout way to turn 50Hz into 60Hz I assure you. How much power does the train require? |

| 790044 | 2009-07-10 09:19:00 | Why not talk to Auckland Transformer Co out in Penrose. If they are still around. I have found them very helpful in the past. PJ Down the Gt Sth Rd just before the bridge into Otahuhu, Freezing Works Straight. |

PJ Down the Gt Sth Rd just before the bridge into Otahuhu, Freezing Works Straight. Been gone for many moons PJ, I heard they had a very large fire. There is a company called TridonicAtco that may be the Phoenix. I'd still investigate a full time online sinewave UPS. I'd be surprised if there wasn't something around with a 50Hz/60Hz switch and that would be the simplest and most elegant option. Even one that didn't have a switch would probably be able to be modded, it could be as simple as changing a link. They wouldn't bother designing two separate models for the 50Hz and 60Hz markets.
