FC-PSU-UNI2450 Universal Input 24V Industrial PSU High-Efficiency Compact

1. High-Reliability Industrial Power Solution​

The Honeywell FC-PSU-UNI2450 is a ruggedized universal power supply engineered for critical automation systems requiring uninterrupted operation in harsh industrial environments. Featuring ​85-264V AC/DC input range​ and ​24V DC output, this unit delivers ​50A continuous current​ (1200W) with ​**≥95% efficiency​ and ​​±0.5% voltage stability**. Its ​die-cast aluminum housing​ provides ​IP20 protection​ for control cabinets while supporting ​​-40°C to +70°C operation​ with ​500,000-hour MTBF. Certified for ​ATEX/IECEx Zone 2/22​ (Ex nA IIC T80°C Gc), it incorporates ​active PFC (0.99 power factor)​​ and ​hot-swappable modular design. Integrated ​N+1 redundancy​ via parallel operation and ​40ms holdup time​ ensure continuous power during brownouts. Designed for DCS, PLC, and safety systems in oil/gas, pharmaceutical, and power generation facilities, this PSU meets ​SIL 2 safety standards​ with comprehensive protection against surges (4kV), shorts, and overloads per IEC 61000-4-5.

​2. Critical Technical Specifications​

Key parameters include ​universal input​ (85-264V AC/120-370V DC, 47-63Hz), ​24V DC ±0.5% output​ with ​​<50mV ripple, and ​50A peak current​ (5s). Efficiency reaches ​95% at 230V AC​ with ​​<0.5W no-load consumption. Protection features include ​overvoltage (28V clamp)​, ​overtemperature (85°C shutdown)​, and ​short-circuit auto-recovery. Connectivity uses ​removable screw terminals​ (16mm²) with ​dual outputs​ for load sharing. Safety certifications cover ​UL 508, ​CE, ​IEC 62368-1, and ​EN 50178. Dimensions are ​245×125×115mm​ (W×H×D) with ​DIN-rail mounting​ (EN 60715). Additional features include ​remote sense compensation (±2V)​, ​current sharing tolerance ±5%​, and ​audible alarm (70dB)​​ for fault conditions. MTBF exceeds ​500,000 hours​ at 40°C per IEC 61709.

​3. Mission-Critical Industrial Applications​

This PSU excels in power-sensitive automation scenarios:

• ​DCS/PLC Systems: Continuous power for Honeywell Experion® controllers
• ​Safety Instrumented Systems: SIL 2-compliant supply for ESD valves
• ​Oil & Gas Platforms: Redundant power for subsea control modules
• ​Pharmaceutical Cleanrooms: Uninterrupted supply for isolator PLCs
• ​Power Generation: Turbine control cabinet backup power
• ​Water Treatment: SCADA RTU power in remote sites
• ​Mining Operations: Ventilation control system redundancy
• ​Chemical Processing: Reactor safety shutdown systems
  Its N+1 parallel redundancy (up to 4 units) eliminates single points of failure in critical applications like offshore blowout preventer control. The 40ms holdup time bridges generator switchovers, while -40°C cold-start capability supports arctic oil fields and freezer warehouses. ATEX Zone 2 certification enables deployment in hazardous areas without additional enclosures.
