Well, you are going to lose a volt. I would put them in series with the + on each one. 1n4004 will work great for this.

What diodes would you recommend and where would I place it? Across the +- output terminal on each GigE-POE? Total load would be something less then .75A. Likely closer to .5.

So yes, diodes would be needed on all of them to prevent reverse power. From: Carl Peterson Sent: Thursday, July 9, 2020 10:02 AM To: AnimalFarm Microwave Users Group Subject: [AFMUG] Combining outputs from 800-GigE-POE If a reverse power situation let's say I had four 24V Gige POE injectors. Each connected to a 800-GigE-POE and set to extract the power. Now I wanted to combine them into one input to power a small switch so that any or all of them could power the switch. Would I need a diode(s) or is there enough isolation in the transformers? ------------------------------------------------------------------------------ -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- Carl Peterson PORT NETWORKS 401 E Pratt St, Ste 2553 Baltimore, MD 21202 (410) 637-3707 -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
