POE 48v --> 5v ~3.5a and also 48v --> 28v ~1a

Hey all need a tiny project quick. I am needing to turn my 48v POE lines to an output of 5v and around 3.5a. Also on the same PCB I would like that 48v to also output 28v and around 1a. Putting both on the same PCB will cut the cost of making them.

Only one output will be used depending on what needs to be powered. Both voltages will not be used at the same time. There also will need to be one solid state relay (so i can turn off the power to my equipment if needed) and the esp32 connected to that (need wifi).

I would like it if you can use step-down modules that are already populated in order to save time for the step down voltage. Will probably need to do the Ethernet connector and output connectors and anything else you deem needed for my project to be SAFE.

Please only apply to this project if you've done POE pcb's before and you know the USA standards set by Underwriters Laboratories (UL).
