It shunts all surges to ground. No, the Plus side has to go to the Plus terminal, irrespective of what ground is.
I could do a bipolar design that would cost a bit more. Or I could do a version with negative ground at the same cost but it would be one more part number.

So couldn't we just put the -48 ("hot") in the + terminals to get the fuse protection? +48/return on the - side.

And it's polarity agnostic, so +48 or -48 or whatever. We asked Chuck to make it and he did. I asked Forrest to make the 2-relay / 3-switch expansion module (to monitor and control the Traco BCMs), and he did it anyway knowing that he probably wouldn't sell a whole lot. These guys know how to listen to customers. Maybe the rest of the vendors can learn something here...

Do you need others? Of course. You need them on hand so that you don’t have to order them when putting in new equipment. You need them for spares. You need them as objets ‘d art...

They are two wires in and two wires out. So if you are using our GigE POE products you are already protected.

Other than everywhere (unless that is the best answer), where would these be used in PoE environments? Say I have PoE radios that pass through one of your GigE supressors, goes into a PacketFlux SyncInjector and I have a DC router on site. Obviously on DC powered radios, I'd use them where I would normally use the GigE ones. I'm thinking to have one on the router feed and one on the the SiteMonitor feed. Do I need others? Well, other than other DC-powered devices I may have. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ---------------------------------------------------------------------------- From: [email protected] To: [email protected] Sent: Friday, August 28, 2015 11:15:08 AM Subject: [AFMUG] It is official
