Wow that's amazing. I think that's outside the normal auto-detect range
too!

Hi All,
We just bought a new 6509-E with 4000w P/S. The specs say it requires a
23
A/240V Input is this the max input current permissible? We have an
existing
6KVA UPS with output of 16A max. I've used the Cisco Power Calculator and
with all the current cards install it will use a max of 1800w way below
the
4000w mark. Can I go ahead and use this 16A UPS to power on the our Cisco
6509-E or do I need a 23A/240V Input?
The 4k PS requires a high range input, 170-264V I believe. If you feed it
high-range voltage, it'll pull the current necessary to run your system.
If 16A is sufficient at the voltage you're feeding it, rock on. If 16A is
insufficient, you'll have issues.
That said, I just witnessed an install two weeks ago where the building
electrical was corroded (or worse), and the brand new UPS was only seeing
89V across a 240V feed. The old UPS was so dead it was in hardware
bypass, yet the 4kw PSes had been running like champs.
