Hi all,
I have one node with 8 devices mikortik ,in the mountains, enough place inaccessible.

I have thinking project electric for indepdence every electrical device.

I have thinking at eight power supply (http://www.interprojekt.com.pl/switchin ... p-567.html) with function ups in parallel connected to same battery pack and installation on PLC eth for monitoring and remote control electrical part. Instead I thought plc a eith ethernet relay type this(http://www.controlbyweb.com/webrelay/resellers.html) single relè for each line dc

my greatest fear is not to pass all from a single apparatus which in the case of malfunction isolate completely the station, but that each devise has its "line" electrical.


Obviously with automatic circuit breakers, and surge voltage

Suggestions?

But if one power supply dies, one radio might not work, so one trip to the remote location, no?
You could use 2 x UPS (110v-220v), 2 power supply, one per ups, diferent voltages, 24v and lets say 19v, connected in parallel.
If one ups or power supply breaks, the other one will work.
