FC-PSU-UNI2450U HONEYWELL

The FC-PSU-UNI2450U is a high-performance, modular power supply. It provides a stable DC output by converting a wide range of AC input voltages. It is engineered for continuous, reliable operation in demanding industrial environments.

• Manufacturer: Honeywell

• Product Type: Universal Power Supply Unit (PSU)

• Mounting: Designed for DIN-rail mounting for easy integration into industrial control cabinets.

• Enclosure Rating: Typically IP20 (Requires installation within a protective enclosure)

• Protection Features: Includes dual overvoltage protection (OVP), short-circuit protection (SCP), and over-temperature protection (OTP).

Product Advantages

• High Reliability for Critical Systems: As a component of Honeywell's major control platforms (like Experion PKS and safety systems), the PSU is built with industrial-grade robustness and a long service life essential for mission-critical infrastructure.

• Universal Input: The wide input voltage range ($110-240 \text{ VAC}$) allows for global standardization and flexible installation in different regions without needing dedicated power supplies.

• High Efficiency: Its efficiency of over $87\%$ minimizes power loss as heat, which reduces the operating temperature inside the control cabinet, enhancing the lifespan of the PSU and adjacent components.

• Protection and Diagnostics: Integrated protection features ensure both the power supply and the connected automation equipment are safeguarded from electrical faults. A relay function is often included to indicate output voltage drop, providing early diagnostic feedback.

• Redundancy Capability: The design supports operating multiple units in parallel to provide fault-tolerant power redundancy, maximizing system uptime and availability.

Important Considerations (Precautions)

• Output Voltage Setting: The output voltage is typically factory-set to $25 \text{ VDC}$ but can often be configured. Ensure the output setting is correct and compatible with the specific Honeywell I/O and controller modules being powered.

• Enclosure Requirements: Due to its IP20 rating, the unit must be installed within a suitable, well-ventilated control cabinet or enclosure that provides adequate protection against dust, debris, and moisture, as specified by industrial standards (e.g., NEMA or IP ratings).

• Thermal Management: Although highly efficient, the PSU should be mounted to allow for sufficient air circulation (natural convection cooling) to maintain the operating temperature within the specified range, especially when operating at maximum load or high ambient temperatures.

• Wiring Practices: All wiring must comply with local and national electrical codes. Use appropriately sized cables and ensure terminal connections are secure and tightened to the specified torque to maintain power quality and safety.

Product Applications

The FC-PSU-UNI2450U serves as the dedicated power source for the I/O subsystems and controllers in complex industrial control applications.

• Distributed Control Systems (DCS): Powers the I/O modules and associated infrastructure in the Honeywell Experion PKS platform used in large-scale process industries.

• Safety Instrumented Systems (SIS): Provides power for Honeywell's safety platforms, ensuring the reliability and availability of emergency shutdown, fire and gas, and burner management systems in applications where safety is paramount.
