Re: [Amel] Isolated or non Isolated DC to DC Convertor
toggle quoted message Show quoted text
Hi, more info please, as not that familiar with Amel. Is Amel systen 24V? is it an option to get a DC to DC converter that is isolted? and why have you chosen unisolated? you could get issues with interference esp from autopilot. Don't know much about radio installation but my reading of it is ground plane is not connected to Negative.Wave_rider and I'm boatless.
Broader question I have for you, if your engine block is connected electrically to the saildrive and under ABYC the shore earth is connected to your negative bus. How do you control electrolytic corrosion of your very expensive saildrive.
I believe the euro standard is pretty good certainly doesn't have the corrosion potential. I would think Amel went to some trouble to avoid allowing electrical connection between Shore earth/Battery Neg and saildrive. I would think that any connection between AC earth and DC negative, (sometimes happens in Battery charger) would compromise Amel DC circuit design. I would think any power supply for SSB should be isolated, but check this statement out.
