Modular Power System III

■ 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.
