Environmental Characteristics
Storage Temperature
–40 to 85°C
Altitude
De-rate 2.6% total output power for each 1,000ft to a maximum operating
altitude of 15,000ft. Non-operating storage maximum altitude is 40,000ft.

See Vicor module specifications. A preload may be necessary for modules trimmed down below 90% of
normal output voltage.
[g]
The maximum operating temperature is 40°C. If using a VI-200 with output voltage less than 12V and more than
150W, the operating temperature decreases to 35°C. This also applies when using a FinQPAC™ with output voltage
less than 24V and more than 500W.
Output Studs
New, more robust output studs (with a 3:1 safety margin at 45lbs.in) 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 advantages include:
