The ABB PFXA401S, designated by the part number 3BSE024388R2, is a high-performance power supply and distribution module. It is engineered for use within the ABB Advant Controller and 800xA automation platforms, providing regulated and reliable power to system backplanes and connected I/O components.

Product Datasheet & Parameters

The following specifications detail the electrical performance and structural characteristics of the PFXA401S.

Product Technical Description

The PFXA401S is designed to act as the primary energy source for sensitive control electronics. It features advanced voltage regulation circuitry to ensure that fluctuations in the main power source do not impact the logic processing of the automation system.

Key Technical Attributes:

• Load Sharing Capability: Specifically designed for parallel operation, allowing multiple modules to be linked for increased power capacity or redundancy.

• Transient Suppression: Includes integrated filtering to protect downstream electronics from electromagnetic interference (EMI) and voltage spikes.

• Thermal Management: Utilizes high-efficiency components to minimize heat generation, housed in a ventilated casing for optimal passive cooling.

• System Integration: Communicates its operational status (OK/Fault) directly to the controller through the system bus, enabling real-time power monitoring.

Country of Origin

• Origin: Sweden (SE) / Switzerland (CH)

Note: Production for the 3BSE series is primarily managed at ABB’s advanced manufacturing centers in Sweden, ensuring adherence to strict European safety and quality standards.

Common Questions & Answers (Q&A)

Q: Does the PFXA401S support redundant configurations?A: Yes. This module is frequently used in "1+1" or "N+1" redundant setups to ensure that the control system remains operational even if one power module fails.

Q: How do I identify a fault on this module?A: The front panel is equipped with status LEDs. A green light indicates healthy output, while a red or extinguished LED indicates an internal fault or an input power loss.

Q: Is this module compatible with all S800 I/O systems?A: It is designed for the S800 series; however, it is important to verify the power consumption of your specific I/O cluster to ensure the PFXA401S provides sufficient current.
