I need to find a cheapish (< R1000) solution to keep my router afloat for 3 hours worth of no power (so I can have interwabz access via my laptop).

Anyone know of any good options to go with? I just want to power my Billion router, nothing else.

Help? :confused:
 
buy a normal ups and wire a multiplug to it and plug the router in, heard guys using 600 ups to do it.
 
kas i converted my 1000va ups for my router ran it for no longer than 50 minutes

your best bet is to go buy a usb modem and another laptop battery as you need quite an expensive usp to run your router for 3 hours and even a 1500va wont do it

i also have a billion

i dont know how those okes are getting so many hours and i could only manage 50 minutes on my billion

i even phoned billion who confirmed this

Right now I am looking into wiring directly to a battery instead of a UPS because my router has a 12v DC input, so it might be a better idea.

Will let you know my findings...

Strange, must be something wrong with either the modem or the UPS.

I'm running two routers off a 1000VA UPS and get well over 3 hours out of it. (Only the routers, nothing else.)

This could work very well, but don't run the router of the battery permanently, the battery won't last that long. Use a relay inbetween the battery & the mains, when the mains are on, the relay will cut off the battery & charger, which will charge on it's own. When eskom cuts out,the relay also cuts out, and you're on the battery. If the router uses 500mA (a lot does), then you could theoretically get 14 hours out of a 7Ah battery, aka standard Alarm / UPS battery.

This doesn't sound right. Most routers use 500mA / 1A power, and those UPS's have 7Ah batteries. What else are you running on the UPS? Remember, the transformer also draws current, but this should be minimal

Could probably do it with a R380 600VA UPS with the internal 7Ah battery connected to an external low maintenance battery. If you can do 12V directly from a battery you're obviously better off with that. You just need to figure out how you're going to charge it ;). You also need to manually ensure that you're not draining a 12V lead acid below 11V*, because this will reduce the cycle life of the battery, which is why I prefer to hook it up to a UPS. Not that they all cut off where they're supposed to.

I have a 1000VA UPS (24V) connected to 2 x 68Ah 12V batteries (R800 each) and I cleared Tuesday's 6 a.m. to 10 a.m. load-shaft with no problems. I'm running a PC, 22 inch LCD screen and some USB peripherals off it. I think my setup might be overkill but I wanted to leave my options open for adding more devices like signal booster for the TV card and maybe a small lighting rig with some ultrabright LEDs.

*I've seen cut-off values of 10V for a 12V SLA battery on the internot. The 11V value I gave there is purely anecdotal, so if it doesn't agree with your reference - bite me :p.

Problem is it's not minimal. On a cheap 600VA UPS with 1 x 12V/7Ah battery I've seen a 1A load just from the inverter. The situation improves for larger UPSs that have more batteries giving 24V, 48V etc.

I take it the 2x 68Ah batteries are in series, giving you 24v, right? How do you charge these?

Slowly :D. They're hooked up to the batteries inside the UPS. Temperature looks normal for a 1KVA, (I have quite a few at work), so the transformer is coping.

I get 90 minutes or so from my 600 UPS too - just the ADSL modem on it.
Lasts about as long as my notebook battery... :p
