Wow! That was a fast reply. Thanks.

Here is where I am coming from. I have half a dozen of
these, without pure sine wave output ranging from 450 to
1500 VA. They power my computers, door locks, home theater,
etc. during power outages. I have unplugged them and
attached a lamp for emergency home lighting during ice
storms, etc. when power was down.

Obviously Automatic Voltage Regulation (AVR) requires a
voltage to regulate and battery charging requires a source
as well but I want to use the UPS feature to provide power
when the line is disconnected. I know they can do it because
I have already done it. My question is about the peculiar
requirements of a set of photographic strobes. They draw
several amps for a fraction of a second then drop to a low
rate. I don't have the real numbers here now.
