johna Posted May 16, 2020 Share Posted May 16, 2020 I am looking a power supply to use with Peco point motors and was wondering if I can use one from an old laptop?. I think it's 19v. Johna Link to comment Share on other sites More sharing options...
Sol Posted May 16, 2020 Share Posted May 16, 2020 Two aspects:- 1. momentary switches to operate them 2. at least a 3 amp supply & ideally use a CDU. 1 Link to comment Share on other sites More sharing options...
Simon G Posted May 17, 2020 Share Posted May 17, 2020 I made a simple CDU using the circuit provided by Brian Lambert on his website. It cost just a few pence, using only simple components and works well throwing multiple points simultaneously. Link to comment Share on other sites More sharing options...
Suzie Posted May 17, 2020 Share Posted May 17, 2020 A 19V supply should be OK - most will supply the 4A required to operate a single motor at a time without shutting down. If it does shut down or you need to operate more motors at once then get a CDU as well. Link to comment Share on other sites More sharing options...
