■ Reliability: Automatic load shar
ing of dual supplies reduces the
burden on an individual supply,
increasing the overall reliability and high MTBF.
■ Serviceability: Local status indi
cators, disconnects, and plug-in
cable assemblies facilitate on
line fault isolation and replacement.
■ Monitoring: Provides system DC
power outputs, field power out
puts, fan status, and cabinet
temperature monitoring.
■ Industrial Quality: Designed for
operating temperatures as high
as 70o C (inside cabinet) as well
as MIL-STD ratings for vibra
tions, IEC standards for EMI and
RFI, and UL ratings for flammability.
■ Price/Performance: Power factor
correction, electronic output
protection and lower costs are
inherent features.
■ Upward Compatibility: Compact
design allows for use in the new
standard ABB cabinets and as
replacement for older power
systems supplied with
Symphony™ and INFI 90® OPEN systems.
