 | | 9V Speed Regulators —Mark Harrison
|
| | | Hi all, I have a mystery. I just got a 4564 which naturally comes with a speed regulator. It also came with a 120V transformer which will never get used. I wonder what happens when you plug it into a 240V power supply, No can't do that either power (...) (26 years ago, 19-Nov-98, to lugnet.trains)

| | | | | (...) The transformers put out unregulated AC, unregulated means the voltage will vary depending on the load. It will need to put out at least 9V when fully loaded but will probably put out nearer 12V when unloaded. Matt (26 years ago, 19-Nov-98, to lugnet.trains)
