Hello Ian, I was surprised to see that Amel are still using this outdated technology. As I understand it these things are basically a lot of resistors which is why they have low ouitput and need to be in a ventilated locker to get rid of the heat, much like an electric fire! I fitted a 25 amp switchmode 24/12volt converter behind the forward instrument panel and I suppose one day I will put the Sailor voltage droppers in a boat jumble.
