The indoor version that looked like an elongated coupler, and an outdoor version that was a plug on a pigtail with a jack on the other end. They are about $20 for either one. Part number INS-8023AF They are converting from 48v 802.3af to 12V passive PoE on the spare pairs. Are you looking at the same application, or something else?

There's also the Traco DIN rail mount (TCL series, and that will be over $50/ea), but that is also pretty large. What application? On 11/30/2015 4:19 PM, Chuck McCown wrote: It is huge.

We have used these to power radios off batteries for installers. They are adjustable - we set them 48v out on 16.2v battery packs. http://www.amazon.com/DROK-Converter-Transformer-Regulator-Inverter/dp/B00BZR9PBW Adam From: Af [mailto:[email protected]] On Behalf Of Chuck McCown Sent: Monday, November 30, 2015 12:38 PM To: [email protected] Subject: [AFMUG] DC-DC Converter Looking for the smallest cheapest 12 volt to 48 volt unit that will do 20 watts.
