QUOTE (zmil @ 16 Jun 2008, 12:59) <{POST_SNAPBACK}>What I should have said is:
The greater the input voltage , the more regulation required and the less current available to the track
The closer the input voltage is to the track voltage - the maximum current is available to the track
I hope thats a bit clearer
Regards Zmil

Not sure that's right either! Regulation in the command station will generate as heat an amount of watts equal to the amps being drawn multiplied by the number of volts dropped, plus something for inefficiency. So crudely speaking dropping twice as many volts at the same current will just dissipate twice as much heat. The amount of regulation can only limit the current available if this causes overheating in the command station, which should not happen in any properly-designed command station being used within its design voltage and current ratings.
