had a job going on at work where we're replacing hundreds of power
supplies in some modules sent in by a customer. These are mostly linear
DC power supplies, though I think some models are switching supplies.
We're replacing everything with new ones whether the old ones are bad or
not. This means I have the chance to grab possibly dozens of good
working power supplies for possible use on the future layout since the
ones being removed will just be scrapped.
The power supplies I have seen come in 5 volt, +-12 volt or +-15
volt (selectable), 24 volt, and 28 volt outputs. The 5 volt, 24 volt and
28 volt units come in sizes up to several amps, but the +-12 volt units
are only 1 amp output.
The only use I can see for 5 volts is building lights or some other
form of animation, etc. The +-12 volt supplies can be used for turnout
machines but I don't know how much a Tortoise or other stall motor
draws, so I'm not sure how many could be powered from a 1 amp supply.
I'm not sure of any use for the 24 volt or 28 volt power supplies. I
think that's too high of voltage to use for an HO scale DCC booster
power supply. Don't they require something in the 15-20 volt range?
Any other ideas for using power supplies on a layout?
