PostPosted: Sun Jun 05, 2005 11:04 pm    Post subject: 12vdc PSU w/ battery instead of UPS for power backup? Reply with quote Back to top

Hi folks,

I work a lot with 12vdc systems. The Linksys RT31P2 (the "phone adapter/router" Vonage sent me) is a 12vdc device. I might try setting up a 3 amp 12v power supply with a 7ah battery for power backup. The supplied PSU is rated 12vdc @ 1000ma (1 amp), so the maximum drain could not exceed that (except maybe brief peaks). I plan to read the current used by the device with a meter (especially when all phones are ringing, which can jump the phone line voltage to about 90!) so I can get an idea of peak and average current. I doubt if average exceeds 200 ma or so. That would mean a backup time approaching 24 hrs. I hope I don't need that much! (I will report back with on-hook, off-hook, and ring currents if anyone is interested.)

This would probably void the warranty on the Linksys. I have some spare power supply plugs like the one in use, so rather than cutting the cord and using the supplied one, I can rig up a new one to the 12v PSU. I will of course need to verify the polarity of the plug (typically center = positive). I think if the voltages are very close, and the current capacity is adequate, I should have no problems.

It should be a lot more efficient to just supply backed up 12v power, rather than using a UPS which, during a power outage, typically runs off a similar 12v battery to the one I plan to use, steps up the voltage to line level (115 vac), then the Linksys power supply changes it back to 12v. Kind of like ordering decaf and putting a caffeine pill in it.

I'm going to consider a low-voltage cutoff switch as well, so the thing will go dead if the battery gets down to say, 10.5 volts. Don't want the router to freak out/self-destruct.

Anybody tried this? Comments?

Thx,

John

I've used my cable modem and RT31P2 (both 12V) wired directly into a 12V UPS battery. They ran just fine for a couple hours, until the battery got too low... and It was a pretty crappy old battery.

That will work just fine. I see that you didn't include a fuse to prevent other anomalies!? You may want to...
Also, your calls may have less noise due to the use of pure DC.
You could install a solar panel and trickle charger to keep the battery charged, this would save you the worry of ever loosing service until the cable/dsl line backup supplies go down.
Just a thought....

I figure, if the router does something that would make a fuse blow, then it's probably time to get a new router anyway. Still, a fuse wouldn't be a bad idea if you're rigging up something permanent.
