I just bite the bullet and use a Mean Well RSD 200W unit, it’s overkill, and not DIN rail, but it works good.
The other solution that comes to mind is a 24V to 24V converter with isolated output, then stack the output on the existing 24V. It appears that Sola makes one, or there’s this very pricey 240W beast from Phoenix Contact: http://www.alliedelec.com/search/productdetail.aspx?SKU=70239258 From: Jeremy Sent: Thursday, January 15, 2015 6:27 PM To: af@afmug.com Subject: [AFMUG] Power AF24 with GIGE-POE-APC - 24v-48v DC-DC I don't want to use the Tycon AF24 24-48V POE because it doesn't offer surge suppression, and it is another big plastic box. All of our sites are already standardized on GIGE-POE-APC surge/injectors. They are 24v sites. I need a decent 24-48V upconverter, preferably DIN mount, that has enough juice to power the AF24. Is anyone using a similar setup? Recommended products?
