ConverterPAC Functional Description (See ConverterPAC Datasheet and/or Design Guide for complete information on all ConverterPACs.)
Continued
FlexPAC
The FlexPAC output assembly consists of from 2 to 4 discrete outputs that convert the
high voltage bus to the desired output voltage. Each FlexPAC output can be manually
trimmed from 2V to 25V and supports up to 5 amps with a maximum output power of
50W per output. All outputs maintain less than 50mV noise over the entire output range.
All outputs support local sense only. For electrical trim options and specific output
sequencing contact the factory

** All the above mentioned ConverterPACs can be used in both the PFC MegaPAC and PFC MegaPAC-High Power except the FinPAC which
currently can only be used in the PFC MegaPAC-High Power. (The UniPAC - not listed above - cannot be used either in the PFC MegaPAC or
the PFC MegaPAC-High Power. Currently, the UniPAC is only used in the 4kW MegaPAC.)
Note: All ConverterPACs mentioned above can be paralleled EXCEPT the DualPAC, JuniorPAC and RamPAC.
