This is a 2U Power Supply
Assembly (PSA) primarily for an
ATX type product, comprising of
one or two AC to 12V Power
Supplies (PSU), and a Power
Distribution Unit (PDU), mechani-
cal housing and output wiring
harness with connectors. Where
only one PSU is required, a blank
module will be installed in the
remaining slot.
