ABB Modular Power System III Features and Benefits

The Modular Power System III (MPS III) is specifically

designed for powering Harmony rack modules and associ

ated field mounted devices. The MPS III can provide 5. +15.

and 24 VDC system power as well as 24. 48. and 125 VDC for

field powered devices. Special features of the MPS III

include: power factor correction, on-line power supply

replacement, power and cooling status monitoring, and

adaptability to various power input sources. The MPS III

assembly includes all the hardware necessary for AC input

power distribution to the individual power supplies, DC out

put distribution, power and fan monitoring, interconnecting

cables, and cabinet mounting hardware.

A family of preconfigured power supplies has been engi

neered to provided various combinations of voltage options

and associated power ratings. The MPS III is designed to sup

port 2N power redundancy. Multiple preconfigured power

supply configurations are available to facilitate matching the

most cost-effective solution with project power requirements.

Detailed specifications relating to these supplies are listed in

the MPS III data sheet.

Features and Benefits

■ Inputs: 120/240 VAC or

125 VDC power feeds allowing

mixed AC and DC operation.

■ Outputs: Provides Harmony sys

tem power of 5. +15. and 24

VDC and field power of 24. 48 and 125 VDC.

■ Availability: Built-in power dis

tribution schemes support

single and dual (main and auxil

iary, AC and DC) power feeds

for 2N power configurations.

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.
