Power Factor of TrueCharge chargers?

Hey group,

I fired email off to Xantrex the other day to find out what the power
factor of the TrueCharge battery chargers is. I figured I'd probably
find out here faster. It doesn't appear in the spec sheet or the
owner's manual.

The Xantrex/Statpower inverter-integrated chargers obviously use PFC
since they spec out at 0.99. I had always assumed that the TrueCharge
units would use PFC too, considering the price of the things, but the
lack of a spec has me second-guessing this assumption.

I believe that you are correct in assuming the P.F. is .99 or so
in those chargers too.
Also, a bunch of app notes are on the XantreX site but don't know if
it will help or notl

Sadly it's nothing of the sort.

Finally got a reply from Xantrex. The 40+ has a PF of 0.68.

Further to this, it's not that much of a surprise that there is a
significant difference compared to the inverter-integrated chargers
from Statpower. With the latter it is possible to use the inverter
bridge switches for power factor correction when operating in charger

Is this (40+) a  "True Charge"  model ???   I thought that their clame
to fame was that they were power corrected chargers.  If their PF is
.68 then they are of course not power factor corrected.
