Hello,
I'd like a bit of advice / recommendations for managing the output of a 48v DC supply:
- The output will supply up to 10A of current to a servo motor driver and isolated DC:DC converter.
- The powered device will be on the other end of a cable.
- It's possible that the cable could be connected to lower voltage powered devices from other systems.
I think I need to do detection & classification, soft start, and disconnection detection. My idea is to use a PoE PSE controller (such as LTC4279, LTC4274, LTC4291) to perform these tasks, modifying the sense resistor, MOSFET & output protection passives to suit the higher current.
At the PD end I envisage using a LT4321 & LT4293 with similarly uprated current capacity.
Has anyone done something like this before / sees potential problems of doing this way / can suggest a better solution?
Many thanks in advance for your ideas, guidance or solutions.
