Battery Backup

post #1 of 4
Thread Starter 
Wasn't really sure where to place this thread, so here goes. ( my first one by the way )

I'd say within the next 2 weeks. My system will be the Denon 4520, the Sony KDL-70R550a, ps3, dvd player, and a fios cable box.

I live in a neighborhood where the power tends to go out for a split second at least 2 times a day. So having the cable box on a battery back up is very important. I hate waiting for it to reboot, and then forget what show I was watching by the time it comes back on. I know I can get a pc apc for that and be ok. But seeing for the first time in my life I'm putting some higher quality gear together. I thought maybe I should power back some of the other gear as well.

I do have a power conditioner and surge. I've been reading more about the brown outs and such too. So, I just thought maybe I should spend a little more to try and protect my equipment better.

Any suggestions. I'd like to keep the cost below 500.00 if a can....

Thanks

I don't have a lot of knowledge about the feasibility of battery backup for power-hungry components like amps. But I will add that if you have frequent power problems, you might consider a whole-home surge protection system. They're surprisingly inexpensive.

(1) The device you are looking for is called an "Uninterruptable Power Source" (UPS)

(2) UPS are obviously rated in Volt Amps but there is a third hidden spec called "Run time".

http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BE350G&total_watts=200



So, for example if you put a 50 watt load on the indicated device, it might run for 18 minutes without external power. At 25 watts, they claim half an hour. This is a $50 device from a well-known manufacturer.

I'd find a Kill-A-Watt or similar power drain measuring device to use to determine the average power drained by the equipment I want to protect, and then use manufacturer spec sheets to see what it would cost to get the sort of protection I need.

BTW, IME the most likely to fail component in a UPS is a sealed wet cell battery that usually takes a technican with modest skills to replace. They run something like $40, depending on the capacity of the UPS and are usually gone after 3-5 years.

Here's one made for home theaters: http://www.furmansound.com/product.php?div=02&id=F1000-UPS_CE

It's about three times the capacity of the APC, but costs about $700. It has IR blasters so it can be programmed to shut down your components.

Looking at the link that Arny K. posted, you could probably get away with the APC based on capacity but you'd have to be there to shut everything off before its juice ran out.
