ConverterPAC Functional Description (Cont.)
FlexPAC
The FlexPAC output assembly consists of from 2 to 4 discrete outputs that convert the
high output 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 powerof
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
