Power Supply for Multiple Components

[oarsout]

I have five Levolor motorized blinds. Each runs on 12 x AA batteries in a series (18 volts & appx 1.5 amps, I believe).
I want to get away from buying and replacing 60 batteries every few months.
Can I operate all five (they run simultaneously) with a single 18 /1.5 power source
- would I need five separate 18/1.5 transformers
- would I need some type of power regulator
- would I need a higher amp rating (would it be simply 1.5 x 5?)?
What is the easiest and most affordable solution for this scenario?

Thanks so much for your help.

1.5A seems a lot for AA batteries ...

Invest in rechargables. They'll last longer in use and can be recharged some 500 times before needing replacement.

If you're ok with running cables to the battery boxes (could be unsightly in an application?) then a single PSU will work IF you only operate one blind at a time. The actual operating voltage isn't important in such a simple application and a common ex-laptop PSU (19V@whatever amps) would be more than sufficient without requiring any regulation.

You can get ex-laptop PSU's that have 19V at 6 or 7 amps output which should be enough to run all blinds at once given the short duty cycle.
