The MegaPAC family of products offers four different versions of user configurability
to meet almost any set of input and output requirements. Leveraging Vicor modular
DC-DC converters, MegaPAC family products combine feature-laden front ends with
slide-in output assemblies called ConverterPACs.
User configurability is at the heart of every MegaPAC. A wide variety of the same
length ConverterPACs™ can be installed, exchanged or removed with the turn of just
one screw. This means the MegaPAC can be reconfigured to meet evolving power
requirements. Given its range of configurability, the MegaPAC is appropriate for
virtually any application from prototype through production.

MegaPAC Configuration
DC-DC Converter
At the heart of every MegaPAC are Vicor zero-current switching, DC-DC
converters. The modularity of the design combined with the breadth of the
product line means virtually any output voltage can be provided.
ConverterPAC
ConverterPACs are the slide-in output assemblies that allow each MegaPAC
to be easily configured to user-specified output requirements. Using the
Vicor DC-DC converter, up to 600W of output power can be provided
per ConverterPAC. Larger power needs are easily handled by paralleling
ConverterPACs.
MegaPAC
Each MegaPAC houses an array of user-selected ConverterPACs to provide a
customized power supply. Using a different front end for each product line,
almost any input power can be accommodated. The result is a customized
power supply with off-the-shelf delivery.

PFC MegaPACs: The maximum operating temperature is 40°C. If using a VI-200™ with output voltage <12V and >150W, the operating temperature
decreases to 35°C. This also applies when using a FinPAC™ with output voltage <24V and >500W. Mini MegaPAC & 4kW MegaPACs: The operating
temperature is 45°C using any combination of modules and output voltages as long as the front-end rating is not exceeded. Normal derating applies to half
power if the ambient temperature is 20°C hotter.
