ABB Bailey PHARPSCH100000 MPS III Power Supply Chassis

Product Introduction

The ABB Bailey PHARPSCH100000 is a robust Power Supply Chassis that belongs to the MPS III (Modular Power System) product family. Designed for use in Bailey INFI 90, Net 90, and Symphony DCS systems, the PHARPSCH100000 provides a modular and scalable framework for mounting and powering multiple MPS III power supply modules. It serves as the physical and electrical backbone that connects field power to distributed control processors, I/O modules, and communication interfaces.

This power chassis accommodates hot-swappable, redundant power supply modules, ensuring continuous operation and minimizing downtime in mission-critical industrial environments. It is engineered for high availability, modularity, and system flexibility—making it ideal for control systems that demand uninterrupted power delivery, load balancing, and fault isolation.

Built from industrial-grade materials and conforming to ABB’s stringent manufacturing standards, the PHARPSCH100000 is a trusted backbone in process automation systems that operate around the clock in harsh operating conditions.

• Global Certification: CE, UL, and RoHS compliance ensures suitability for international deployments.

• Field Proven Reliability: In use globally across heavy industry with a long track record of dependable service.

• ABB Support Ecosystem: Fully backed by ABB’s lifecycle services including spares, repair, and modernization.

Frequently Asked Questions (FAQ)

1. What is the primary function of the PHARPSCH100000 chassis?
   It provides structural and electrical support for ABB MPS III power supply modules in industrial control systems.

2. Can I use the chassis with both AC and DC input modules?
   Yes. The chassis itself is passive; voltage input depends on the installed power supply modules.

3. Does the chassis include internal cooling fans?
   No, the base unit does not include fans, but optional external cooling can be integrated if required.

4. Is it possible to mount this chassis in a standard 19-inch rack?
   Yes. The unit is compatible with industry-standard rack mounting.

5. How many power modules can be installed simultaneously?
   It supports 2–4 modules, depending on the configuration and redundancy requirements.

6. Can power modules be replaced while the system is running?
   Yes, the hot-swappable feature allows modules to be changed without system shutdown.

7. What are the benefits of redundancy in this chassis?
   Redundant modules ensure continuous power even if one module fails, improving system uptime.

8. Is the PHARPSCH100000 compatible with other ABB product families?
   It is specifically designed for the MPS III family and ABB Bailey control systems.

9. How do I monitor the health of the installed power modules?
   Most modules offer status LEDs or feedback to the control system for health and fault monitoring.

10. What maintenance is required for the chassis?
    Regular checks for dust, terminal tightness, and physical integrity are recommended. No internal active components require servicing.
