Product Description
The Honeywell FC-PSU-UNI2450U V2.1 is a high-capacity, industrial-grade power supply module designed for use in Honeywell Safety Manager and FSC systems. It converts universal AC mains power into a stabilized 24VDC output to power critical safety controllers, I/O modules, and field devices. The V2.1 revision features enhanced thermal management and improved filtering to ensure high availability and long-term reliability in “always-on” safety-instrumented systems (SIS).
Application Areas
- Safety Instrumented Systems (SIS): Providing reliable power to Emergency Shutdown (ESD) systems.
- Fire and Gas Systems: Powering critical detection and alarm loops in hazardous areas.
- Oil & Gas Refineries: Centralized power distribution for offshore platforms and onshore processing.
- Chemical Processing: Ensures continuous operation of safety controllers to prevent industrial accidents.

Product Specifications
- Weight: 3.10 kg
- Dimensions: 28.5 cm x 18.0 cm x 12.5 cm
- Country of Origin: Netherlands / USA
- Cooling: Forced air (Integrated Fan)
Operating Precautions
- Ventilation Clearance: Maintain at least 50mm of clear space around the fan intake and exhaust vents to prevent thermal shutdown.
- Grounding: Ensure the protective earth (PE) terminal is securely connected to the system ground bus before applying AC power.
- Load Balancing: When used in redundant configurations, verify that the load sharing between multiple PSU units is calibrated according to Honeywell Safety Manager specifications.
- Output Voltage Adjustment: Do not adjust the output voltage potentiometer while the unit is connected to sensitive safety controllers without monitoring the bus voltage.
