I need to buy a higher wattage UPS to cover these items. The puny 325 watt was a waste of time.

61" DLP Samsung tv

Two Dish receivers, one is a 622 dvr

One Pioneer 5.1 receiver

One security dvr, four cameras

One cd player

One XBox


The little 325 ups want pull the tv, the 622 and the security dvr now.

Look at the power rating on all your equipment and add it up.


The general "rule of thumb" is to oversize a UPS minimum 1.5x the highest load it will carry, 2x oversize is preferred.


One thing you will notice is your equipment's power consumption is rated in Watts and UPS's output power is ratted in VA (volt amperes).


I do not have the space here to explain how and why Watts and VA are often the same and more often different measurements of the same load, but it has to do with the power factor of the load.


Anyway just figure a UPS is good for about 75% of it's VA rating.

That's to say a 1000VA UPS is good for about a 750 Watt load.

APC has a couple of ups for high-fi but it doesn't come cheap.

Hi,


And in addition to the VA rating you need to consider runtime.

I would say just back up the items that are a pain in the butt to reboot. Like the satellite receivers, since they take a while to re-lock and download the initial info. The CD player so it doesn't lose its place on the disc. At least you will be covered for brief "power blinks" like I get in my area. Your small UPS may be adequate for these devices.


The 5.1 receiver and DLP monitor are going to require quite a bit of power, which will be an expensive UPS - even if you accept a short runtime. To get a meaningful runtime for an extended power outage, you need a generator, IMHO.

I doubt its enough but I put my Cyberpower 825 in the place of the CP 325 for the time being.

Im thinking Im going to need a 1000 or bigger also.


I agree the Dishnet 625 dvr and the security dvr is probably the most important since they use the hardrives and take a while to reboot. I only had the tv on it for protection.


Basically Im just trying to eliminate those power blips that are just long enough to cause all of these to reboot. Im not looking to use the UPS for any long time running.

There are basically two kinds of UPS's. Those that switch to battery when they detect a power problem and those that (in essence) run off the battery all of the time, there is no switchover at all.


The first kind don't always prevent power glitches from getting through and messing up equipment, such as causing a re-boot.


The second kind are (as you might expect) more expensive.

My cheapo UPS keeps my PC from rebooting. Dunno how well it will do with satellite tuner boxen, but my understanding of switching power supplies is that they are fairly tolerant of this sort of changeover. I think these tuners have that kind of PS.

If you want to watch movie during power outrage well buy a generator gonna be cheaper, usually people will buy a UPS for their projector so in case of power lost they do have enough power to run the fan to cool of the lamp.
