Only those products bearing the UL Recognized Component Mark should be considered as being
covered by UL's Recognition and Follow-Up Service.
The UL Recognized Component Mark generally consists of the manufacturer’s identification and
catalog number, model number or other product designation as specified under “Marking” for the
particular Recognition as published in the appropriate UL Directory. As a supplementary means of
identifying products that have been produced under UL’s Component Recognition Program, UL’s
Recognized Component Mark: , may be used in conjunction with the required Recognized Marks.
The Recognized Component Mark is required when specified in the UL Directory preceding the
recognitions or under “Markings” for the individual recognitions.
Recognized components are incomplete in certain constructional features or restricted in
performance capabilities and are intended for use as components of complete equipment submitted
for investigation rather than for direct separate installation in the field. The final acceptance of the
component is dependent upon its installation and use in complete equipment submitted to UL LLC.
Look for the UL Recognized Component Mark on the product.

Product Description
The PFC MegaPAC is an AC-DC/DC-DC chassis based configurable power supply that includes an EMI
filter, a single phase power factor corrected front end, cooling fan, and 8 output slots that can provide up to
32 outputs. The PFC MegaPAC accepts a 100-240 Vac or 300Vdc input and the output slots are populated
with ConverterPACs or FlexPAC subassemblies. The ConverterPACs are constructed with the Vicor
Corporation VI-J, VI-200, or 2nd Gen FastTrak series of modules. The FlexPAC is an approved component
that can provide up to 4 outputs totaling 200W max.
The PFC MegaPAC is designed for building-in and can provide a maximum output power of 2400Wmax. The
product is for use with Information Technology Equipment. The baseplate temperature of the Vicor modules
should be monitored in the end product.

Engineering Conditions of Acceptability
For use only in or with complete equipment where the acceptability of the combination is determined by UL
LLC. When installed in an end-product, consideration must be given to the following:
The following Production-Line tests are conducted for this product: Electric Strength
The end-product Electric Strength Test is to be based upon a maximum working voltage of: PrimaryEarthed Dead Metal: 264 Vrms, Primary-SELV: 400 Vpk
The power supply terminals and/or connectors are: Not investigated for field wiring
The investigated Pollution Degree is: 2
The following end-product enclosures are required: Mechanical, Fire, Electrical
The PFC MegaPAC is designed for building-in and must be installed in accordance with the
manufacturer’s instructions.
The maximum baseplate temperature of the 1st Gen VI-200 and BatMod Modules is 85°C.
The maximum baseplate temperature of the VI-J and 2nd Gen FasTrack Modules is 100°C
The maximum case temperature of FlexPAC is 50°C.
Series or single output voltages less than 60 Vdc meet the requirements of SELV.
Series or single output voltages above 60 Vdc are non-SELV and should be considered hazardous
secondary.
VI-J outputs are limited to less than 40 Vdc to be considered SELV.
Outputs greater than 240 VA should be considered hazardous energy.
An external fuse, Bussmann ABC-15, or Littelfuse 505 series rated 15A was used during fault
testing.
