Minor Changes for PFC Mini Shipped October 2005 Onwards
As part of our philosophy of continuous improvement for the PFC Mini, Westcor made
a number of changes to the unit. Usually such actions have no impact on form, fit, or
function of the supplies. In this instance, the improvements required minor changes
in the external appearance of the supply. The fans have been moved 0.62" and are now
centered. The D-Sub logic connector has also been rotated 90 degrees. Please see the
following photos for a visual comparison. No other external dimensions, mounting
locations, or performance characteristics have been changed.
