What Power Supply??

[Didier B]

I do not know how protected the ND buck converters are, maybe they shut down ? or melt down under overload ? I've never tested this. I cannot recall anything in the data sheet about this.

I have a metal boat (Ovni 395) and are paranoid when it comes to isolation of the computer system and the rest of the boat. Wen you have experienced grounding faults and burned signal cables in a lab, you tend to forget. Same applies onboard a metal boat where negative is also isolated from the hull and superstructure of the boat.

You can read more about it here : https://sites.google.com/site/olewsaa/ya...-isolation

Have fun,

Hi Olewsaa
I have been reading data sheets for more than 40 years now, and never saw one which predicted a future melt down !!!
The module is fully protected (once a Schottsky diode is used on the In+ line) : overload, over voltage, over current, out shorted, polarity reversion etc.
See  XL4015 datasheet pdf
As you mention in your note about isolation, the presence of a large coil is a must to avoid interference .
Have you checked the claimed galvanic isolation, including the minus line ? This would require a transformer able to deliver 15 W ?
My boat too is made of aluminum (Mopelia 2000) and I just avoid carefully any contact between the ground (hull, deck) and any wires, cables, or electrical equipment ... which includes mechanical protection of the cables ...
I am slightly paranoiac too, but my whisky treatment gives good results .
