SYSTEM POWER SUPPLY UNIT
FC SERIES
DATA SHEET
PXJ
FC series receiving instruments, converters, computational units and distributors which are mountable on instrument panels are designed in principle for a power supply of
24V DC.
Type PXJ is a regulated-voltage power supply to be used
as a common system power supply unit for providing 24V DC
to the panel-mounted instruments from a commercial line
power outlet of 100V AC. It adopts a switching regulator
system for realizing a compact and highly efficient common
system power supply unit. It is also prepared as a common
system power supply unit equipped with a battery backup
system which permits parallel operation to assure failurefree power supply of even higher reliability. The power supply
unit can be equipped further with a protective function against
line power failure in cooperation with a digital component.
