The Netgear FS116P uses a total of 88watts (volts x amps=watts) under maximum 
load so to figure out run time on ups use the following equations.

First you need to get a load ratio by divideing the total va / watts

So an 1000va ups 1000va/88watts= 0.088 or rougly 9% load

Now if that ups lasts 10mins (take this from the mfgrs box and always round 
down) under full load you would get the max run time looking at the load and 
runtime under fully load

So in this case a 1000va would roughly get you 111 minuets (1hr 51mins)

Hope that helps out.

Philip Mullis

Drew,

I use the Ultra 1000kva units from TigerDirect, if you go to their store they 
have (had it's been a few weeks since I've been there) them as in store 
specials at $68, online their 107. They're hard to beat for the price.

My most heavily loaded one will keep 5 small servers, a router and two modems 
running for at least 35 minutes ( haven't test any longer ). So I imagine it 
would keep 5 phones and a switch going for quite a while.

I have to power groups of 5 Aastra 480i phones plus a small PoE switch (Netgear 
FS116P)  for 2-3 hours. There has to be 1 UPS per group due to the office 
layout. 

Has anyone found a low VA/ long battery life UPS at a reasonable price? 

What are others using? 

regards, 

Drew
