The ABB PHARPS11000000, also cataloged as the PHARPS11000000 Power Supply Module, operates as a dedicated hardware component for regulated DC power conversion and system bus distribution within Bailey Infi 90 Modular Power System III platforms.

Model Number Decoding

The PHARPS11000000 represents the base power assembly under the Modular Power System III (MPS III) series. The alphanumeric suffix structure designates internal component revisions and voltage bus distribution settings required to power rack-mounted controller chassis and auxiliary process I/O sub-assemblies.

Technical Performance Matrix

System Power Distribution and Backplane Interface

The power supply module regulates main AC input power down to regulated system voltages to sustain internal rack card execution without affecting backplane bus communication velocity. Onboard filtering circuits suppress electrical line noise to ensure maximum I/O density scaling stability while maintaining complete firmware flash compatibility across active processing nodes.

Package Contents

• 1 x ABB PHARPS11000000 Power Supply Module

Mechanical Installation and Electrical Grounding

• Verify proper AC input voltage jumper configuration (115 V AC or 230 V AC) prior to energizing the module.
• Slide the module along cabinet guide tracks until the rear power connectors engage firmly into the system backplane.
• Ensure the chassis ground terminal is bonded directly to the primary cabinet copper earth bus.
• Maintain adequate vertical convection clearance above and below the module chassis to prevent thermal buildup.

Engineering FAQ

• What AC input line voltages are supported by the PHARPS11000000?

  The module accepts standard dual input voltage ratings of 115 V AC or 230 V AC single-phase power.

• What is the primary regulated DC voltage output and current rating?

  The unit provides a regulated 5 V DC output rated for 2.5 A continuous load current (12.5 W).

• What is the minimum holdup time during an AC power loss event?

  The power supply maintains continuous output regulation for greater than 15 ms at full load during power interruptions.

• What maximum inrush current is drawn when applying 230 V AC power?

  The internal soft-start circuitry limits total peak inrush current to less than 20 A at 230 V AC startup.

• Does the PHARPS11000000 module require active cooling fans?

  No, the hardware uses natural convection cooling and contains no internal moving fan components.

• What peak-to-peak ripple and noise limits are specified for the DC output?

  The DC output voltage ripple and noise level is filtered to remain below 100 mV peak-to-peak.

• Can the power supply module be replaced while the rack is fully energized?

  System power must be turned off prior to inserting or removing the power supply from the backplane assembly.

• What is the operating temperature range for panel installations?

  The unit operates continuously within ambient enclosure temperatures ranging from 0 to +60 deg C.
