I live in an apartment building (5 floors) in Portland, Oregon. 90% of the time the power seems stable, but during storms or in the winter months we do experience blackouts, brownouts, and spikes (I also can notice flickering in the lights when running appliances). I'm waiting to hear back from my building if we have any kind of industrial surge protection or power backups.
So at the very least I want to protect our Panasonic PT-AR100U projector with a UPS so it can perform it's cool down cycle before being powered off. For that I'm looking at these units:
1) CyberPower CP1500AVRLCD
2) APC J25B
The rest of the equipment (Marantz SR5006, Apple TV) just needs a decent surge protector, for that I haven't spent much time looking.
What do you guys recommend for surge protection and UPS for under $200? They will probably need to be sperate as the receiver and projector need at least 1000watts.
There is a third option - do nothing.
The cost of doing nothing can easily be zero.
Flickering of lights does not have a lasting effect - it is usually due to line voltage sagging
(IOW becoming less than normal) when some appliance with a motor starts up. The short-term drop might be 10 volts, which has negligible effect on the life of the projector.
As far as your power outages in the winter go, what are the odds that a power outage is going to occur while you are using the projector? That has a lot to do with how many hours per day you will actually have it turned on, which only you can even estimate at this time.
Then there is the matter of the consequences of dumping a projector. We all agree that it is not a good thing, but quantifying the actual damage is kinda hard to do. For example we have a number of projectors at church on roll-around AV carts. The probability that they get dumped is high. We've had them for years and one of them actually failed, but we aren't sure why.
I looked at the devices you mention and one has more capacity than the other, so your question seems weakly formed - you aren't asking about a comparison of apples to apples.
It looks like either would be capable of shepherding your projector through a cool-down cycle. But unlike computers, projectors don't have a formal interface with the UPS that automatically starts the shut down cycle when power is lost. Will you be able to actually do this 100% of the time, given that it would be a manual operation? Remember, you will have to do this in the dark! ;-)
Bottom line is that power isn't exactly reliable around here and I've taken the position that a UPS is not needed, even though I have some good candidates on hand - they just need a new battery. We've lost power about 20 times this summer, and I guess there might have been one forced shutdown of our RPTV more than a month back. So far, no adverse affects have been noticeable.
