Afternoon All,
I'm looking into trying to limit the no load voltage from the uncontrolled output of the Hornby R7229, essentially to power a fixed number of LEDs and thus a fixed load.
My question is, can I use a zener diode to achieve this without affecting operation of the CDU for my points? As the supply voltage varies a potential divider isn't suitable here. I assume both are equally inefficient?
Follow up question, if a zener is suitable for this application is it correct to connect the point motors across the supply (so they're not in series with the z
