have registered this version from LPA before I think they decided to make

"WinPower" ? Are these the Windoze programs that come with the
hardware (ie not Lone Peak Automation software ?).

Haven't measured here but I would expect about the same. I've seen
fluctuations of up to 30 volts and 10 Hz in one part of Scotland when I
worked there !!

Hi Ed,
Yes those two programs mentioned were the 9x & full 32-bit 
Windows/AIX/Linux/BSD/Mac versions that are downloadable from the web 
and use the serial key quoted on the Blazer *00 VA userguides for 
activation.

Having now hooked two complete systems up to the Blazer 800VA - load 
increased from 38% to 58-61% or about 285W.
800VA equates to approx 800*0.6=480W, the 0.6 comes from the cosine of 
the phase-angle difference between mains and AVR output from the 
inverter in the unit.  Your 400VA  can deliver ~240W equivalent without 
overloading it.

I e-mailed Armin at LPA to see whether he could determine which of his 
products might be relevant. There are four currently - UPSMON2/UPSMON 
B/UPSMON C and the latest beta - UPSDAEMN 09D.  It just so happens that 
he acknowledged my e-mail from Indonesia where he's currently on 
vacation, advising he'll investigate when he returns to work.
