The ABB Bailey PHARPSPEP21013 (Part Number: 6644463A2) is a Dual Chassis Power Entry Panel (PEP) designed as a central power interface for the MPS III modular power system, used in ABB’s INFI 90, Net 90, and Symphony Distributed Control Systems (DCS). This unit is engineered to support redundant power delivery, making it ideal for high-availability and mission-critical control applications.

The dual chassis configuration allows the simultaneous connection of two independent power sources, ensuring that connected systems continue to function even if one power feed fails. Its rugged design incorporates internal fusing, terminal blocks, and grounding provisions, all within a compact industrial-grade enclosure. The PHARPSPEP21013 facilitates organized, safe, and uninterrupted power distribution to multiple MPS III chassis or modules, enhancing the overall reliability of ABB automation infrastructures.

Frequently Asked Questions (FAQ)

1. What is the main function of the PHARPSPEP21013?

   It acts as a centralized dual input power entry point for supplying protected and distributed power to MPS III power systems.

2. How many power feeds does this unit support?

   It supports two independent power sources, enabling power redundancy.

3. Can it be used with AC and DC power sources?

   Yes. It is compatible with both AC (120/240V) and DC (typically 24V) inputs based on module setup.

4. Does the chassis include built-in circuit breakers?

   Some configurations include optional circuit breakers, but internal fusing is standard.

5. What kind of power modules is it compatible with?

   It interfaces with MPS III power supply modules like PHARPSM100000, PHARPSM200000, etc.

6. Can it support two separate power chassis simultaneously?

   Yes, each input channel can independently supply different chassis or load groups.

7. Is it hot-swappable?

   The panel itself is not hot-swappable, but the modules connected to it often are.

8. Is additional cooling required?

   Not typically. The unit is passively cooled but should be installed in ventilated enclosures.

9. What enclosure type is required?

   Standard installations use open-frame; however, optional enclosures are available for hazardous areas.

10. How often should it be maintained?

    Annual inspections are recommended to check terminal tightness, fuse integrity, and grounding.
