Beware when you actually move the project into the railway station, there will be noise sources that you haven't considered.
I think I understand that you are now using one SMPS for each sign, and that a sign consumes (3A/5) or 600 mA. Be careful that the SMPS is not underloaded. Some SMPS don't regulate well when the load is less than 5% of rating. |
