Can you guys make a power supply recommendation?

[jmed999]

I have an Elk M1G with a back up battery. I also have an XEP that is currently plugged into an electrical outlet along with the Elk module. All of this is in the Elk can that came as a bundle.

I'm wanting to add a 2nd can and put the XEP in it along with an Uplink 2500 and an XSP. I've decided to have it all on backup battery instead of UPS. Can you guys recommend a power supply for the 2nd can? Ie. Should I buy these...

and a battery

or one of these...

and a battery

In summary...in the 2nd I'll put the XEP, Uplink 2500, XSP, power supply, transformer, and a battery. I need help selecting the power supply and battery.

Any ideas?

Thanks!

What is the total continuous power you need for all of the devices? The Elk P212S is nice because it is supervised but it's only 2AMPS at 12vdc. You might need a 4 amp supply to run those devices reliably in which case I'd recommend an Altronix AL400ULX. I don't think there is a low battery cutoff if that is important to you but there are AC and Battery supervision relays that can be monitored (wired to) on an Elk zone. If you are going to add a second can if doesn't hurt to go a little bigger than what you need now...

I'm really not sure how much power the XEP, Uplink 2500 and the XSP uses. I guess I should get a low battery cutoff too. When you say go bigger are you talking about the power or the can? Thanks!

Well.... Both sort of.

The XSP draws 31mA.
The XEP draws 300mA
The uplink draws 2A accroding to the manual I found.

Thats 2.331Amps. You will need at least a 3Amp supply to run those items. I would install a larger can to fit future stuff, and I would install a "larger" power supply to be able to supply the needed current and then some for future growth. JMHO. Nothing worse than running out of power for something and needing to install yet another power supply to relaize that you might not have enough room to install the new supply, follow me?
