* See Vicor module specifications. A preload may be necessary for modules trimmed down below 90% of
normal output voltage.
** The maximum operating temperature is 40°C. If using a VI-200 with output voltage less than 12V and
more than 150 Watts, the operating temperature decreases to 35°C. This also applies when using a
FinQPAC with output voltage less than 24 V and more than 500 Watts.

Output Studs
New, more robust output studs (with a 3 to 1 safety margin @ 45 in. lbs.) were installed in ConverterPACs,
the slide-in assemblies used in the MegaPAC Family. These new outputs studs are 1/8" longer to allow for multiple
lugs. They are fully compatible with the original flanged nut ConverterPACs for use in parallel arrays. Other advan-
tages include:
• Inner nut (that might become loose) replaced by a brass insert
• Stronger connection to the PCB
• Improved conductivity (less voltage drop and heating)
• Both the stud and panel are less likely to break due to over torqueing
Shown below are the original and re-designed studs.
