CRS328-24P-4S+RM and 54VDC

Thu Apr 12, 2018 9:02 pm

How one would go about supplying this switch from Telco PSU? 100-240VAC PSU that's built in supplies 48VDC and 24VDC. Will modules inside, named "PSE-24", accept 48-57VDC? Is there some place on built-in PSU's board that one can supply 57VDC with, which would then be converted to 24VDC by the PSU? Is there a version with DC-IN PSU planned?

Version with external DC-in like in the CRS112-8P-4S-IN will be nice to me also.

Hey.
You can swap out the internal PSU for Either a dual output dc/dc PSU OR a 24v output dc to dc converter and a 54v output boost converter. I'm making a video explaining how.
Remember this will void your warranty and Mikrotik does not support this modification. I do repairs and modifications on my youtube channel. The video Im making this week shows you how to adapt an ac switch to a dc plant. Look me up. "Ms Fixit" or thefixitgal.

I hope it isnt bad ressurecting a thread.. Anyone successful modding crs328? Since it is dual voltage supply.. Anyone figured how many watts per powersupply ( boost converter) is needed?

Still planning if it is practical to do a 24v or 48v conversion..
