The ABB PHARPS32000000 is a high-performance, multi-output power supply module engineered for the ABB Bailey INFI 90 and Modular Power System III (MPS III) platforms. This module is a critical component within the Symphony and Harmony DCS environments, providing stable, regulated DC power to controllers, communication interfaces, and I/O modules.

Features

• Quad-voltage output architecture (5V, +15V, -15V, 24V DC).
• Supports 2N power redundancy with automatic load sharing for high-availability applications.
• Mixed AC/DC input capability allows for primary and auxiliary power feed integration.
• Online hot-swappable design for maintenance without system downtime.
• Integrated power factor correction and electronic output protection.

Applications

• Power Generation: Maintaining uninterrupted control loops in thermal and hydro plants.
• Oil, Gas, and Petrochemical: Providing reliable power for refinery safety and process monitoring.
• Water and Wastewater: Centralized DCS rack power for municipal treatment facilities.
• Chemical and Heavy Manufacturing: Ensuring redundant power to prevent systemic shutdowns in continuous processes.

Technical Specifications

Installation Guidelines

• Ensure the power system is de-energized before inserting or removing the module from the chassis.
• Align the module rails carefully with the slide guides of the 19-inch rack-mountable power chassis (e.g., PHARPSCH100000).
• Slide the module until the rear multi-pin connectors are fully seated against the motherboard bus bar.
• Secure the integrated faceplate retaining screws to ensure a proper ground path and prevent vibrational dislodgement.
• Maintain adequate clearance around the module to ensure proper airflow and cooling.
