tooth_dr Posted February 23, 2021 Share Posted February 23, 2021 I’m currently setting up an SQM-LE, and rather than run a power supply to the housing, it’s seems to be possibly to supply power via the Ethernet cable. The input voltage on the SQM is 5-6V, but POE seems to be 48V? Can anyone recommend a suitable device? Thanks and clear skies Link to comment Share on other sites More sharing options...

DaveL59 Posted February 24, 2021 Share Posted February 24, 2021 you could use a passive splitter and then hang a 5v PSU at the local end, using the splitter to take the power off the LAN cable to a regular plug. HSeaMall 1 Pair Passive Power over Ethernet RJ45 PoE: Amazon.co.uk: Electronics I use this type for my CCTV cameras since I don't run PoE switches and on a couple I also have an IR illuminator doubled off the same link, there's a few suppliers and they work fine. A smidge of dielectric grease on the LAN connection helps it resist moisture issues. You would have to consider volt-drop if running a long LAN cable tho. 1 Link to comment Share on other sites More sharing options...
