5V supply available? Maybe an Orion for the future? Suggestion

To run Arduino(s) or Raspberry Pi(s) for logging and distributing purposes in the switch cabinet quite powerful and stable DC DC converters are desirable. A single Pi wants 3 A, an Arduino Mega driving dozens of relays possibly more. I am sick and tired of using remote control car equipment which sometimes have a wide input range but dont last very long, get really hot or have a not good enough voltage so regular brown outs happen.

More professional equipment has then AC input which I don't want to have available at all times. DC Battery current obviously I have available.

Have I overlooked anything Victron putting out 5V slightly adjustable at maybe 5 to 10 A? Ideally with a wide range input of 12 to 48V but I will gladly accept current Orion steps so in my case 24/5 - 5 galvanic insulated? If it then had regular clamps and also full power USB ports, that would be epic...

I like to use the Traco Power power supplies for this type of job.

https://www.tracopower.com/products/browse-by-category/show/dc-dc-converters/low-power-off-board-modules/tmdc-60/1/

Models with 5V, 5A output and either 9-36V or 18-75V input.

Hi @ripper

I always use industrial (din-rail mounted) dc-dc converters for this use.
