I have a BK Precision 1665 1-19V 0-10A variable power supply not specifically designed for model trains. Can I use this to power my Bachmann Anniversary Edition 4-6-0 Denver & Rio Grande 81097 on a Aristocraft Brass Track with out damaging it?
Sure. That's an expensive power source! ;)
Keep the DC voltage less than 16 volts. If you need more than that something is wrong.
It's something I already have, but I don't want to do damage.
