ConverterPAC Functional Description (Cont.)
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 2 V to 25 V and supports up to 5 amps with a maximum output power
of 50 W per output. All outputs maintain less than 50 mV noise over the entire output
range. All outputs support local sense only. For electrical trim options and specific
output sequencing contact the factory.
