[Amps] ALPHAs and momentary power outages

Yes, a proper sized UPS would work, but it has to be capable of supplying 
the peak AC power to the amp under load if that is when the power is 
interrupted rather than just the idle power.  That means a UPS capable of 
2500 to 3000 watts peak and would probably cost as much as the Alpha. Those 
in the neighborhood of a KW seem to run about a dollar a watt. I'd guess 
they get more expensive per watt much larger than that as I just looked at a 
1200 watt unit for $1,400.

They really don't have any reserve capacity. Take one a tiny bit past it's 
limit and it'll just shut down, or at least all I've seen so far do.
