Power Plant 10 problems

Hi guys- been reading some troublesome feedback on PS audio gear on their own forums.

Someone had posted about using online sine wave regenerating UPS's instead which is a similar process- for a LOT less money.. Trouble is, I have no idea how to size either.

My new amps will be SS 700W mono's that draw 150W at idle all the way up to 1500W at full tilt. Full tilt would melt my 300W 96dB speakers and my face while I'm at it so how does one size the output capacity of the UPS/Regenerator?

I'm thinking a 2000W device feeding them should be plenty on tap and give huge overhead if needed.

PS Audio dealers aren't plentiful in Ireland so I don't have the luxury of borrowing one to test the draw of my 500W integrated at present.

Then there's the age old logic one should never plug one's amps into anything other than the wall...-.

So far as I can recall, PS Audio name their power regenerators based on the amperage they can comfortably produce. So, a P10 would produce 10A. Since we want 120V, then it is easy to calculate that the P10 can make 1200W of power. In sizing a regenerator to power an audio amplifier, I would want lots of headroom. In short, don't buy a P10 to power the SS amplifier you have described. SS amplifiers operating in AB mode tend to require lots of current. Even a new P20 (which is a newer generation of their design and much better in other ways than a P10) would be a bit stressed.

  I have the opportunity to demo an online double conversion UPS unit so at least I can test the power draw on my 500w unit. Our power supply is 230V not 120v.
  
  An electrically minded friend has suggested the amps would need 6amperes per device @ 1500W which I will never get near.

    It's not that you will need the max output in a steady state situation. The issue is the response during transients and also the output impedance of the power regenerator, which governs the speed with which it can keep up with the audio amplifier's power demands.

Is an online sine wave regenerating UPS really the same as a PS Audio PowerPlant? I think the PS Audio lets you tweak the shape of the regenerated waveform for best sound quality. Plus it has isolated outlets, etc.

A while back the trend was Double Conversion UPS. I am not sure how this differs from an online sine wave regenerating UPS.

I don't know how to size it. Maximum peak current of all devices plugged into it plus 20% perhaps?

  Some of their earlier models did offer the option of re-shaping the wave form. I think that did more harm than good for some of their customers and also the units themselves were not so reliable, so they have dropped that option. I have a current production P15 the effect of which I like very much, but it does not offer wave shaping or frequency alteration. (I haven't had to touch it since installing it a few years ago, so I hope my memory of the owners manual is accurate.)

    The P15 manual indicates that Multiwave is built into the unit. It can be toggled on and off from the remote.

      Good evidence that I have been so pleased with the P15 operating in conventional mode that I have not even considered messing with the wave form. Also, in their earlier power regenerators, multiwave was but one way in which you could alter the wave form of the output, again, if memory serves. My P300, a first generation regenerator for PS Audio, crapped out, and though PS Audio were very responsive in that they supplied a schematic and other info to facilitate repair, they will not themselves take on the repair of those early units. I ended up scrapping it.
