Description

The Honeywell FC-PSU-UNI2450U V2.1 is a high-performance universal input power supply unit engineered for critical industrial automation systems. Designed as part of Honeywell’s Field Controller (FC) series, this DIN-rail mountable PSU delivers robust 24V DC power to PLCs, I/O modules, safety relays, and other control components in harsh environments. The FC-PSU-UNI2450U V2.1 features auto-ranging 85-264V AC/120-370V DC input with active power factor correction (>0.95 PF), ensuring stable operation during voltage sags and surges. Its convection-cooled, fanless design eliminates moving parts for maintenance-free operation while achieving 92% efficiency and ≤150mV ripple noise. With reinforced insulation (3kV AC) and integrated protections (overload/short-circuit/overvoltage), this unit provides SIL 2-compliant power distribution for Honeywell’s Safety Manager and ControlEdge platforms. The Honeywell FC-PSU-UNI2450U V2.1 is UL 508/EN 50178 certified for industrial control panels, making it ideal for continuous process applications where power integrity impacts system safety.

Technical Specifications

Main Features and Advantages

Universal Input Resilience: Operates flawlessly from unstable mains (85-264V AC) or DC sources (120-370V DC) without manual switching. Active PCR maintains >0.95 power factor even at 115V AC input, reducing harmonics by 30% versus passive designs.

Maintenance-Free Reliability: Fanless thermal management extends MTBF >300,000 hours. Aluminum housing with conformal-coated PCB withstands 95% humidity and corrosive atmospheres. Automatic recovery after fault clearance minimizes downtime.

Enhanced Safety Compliance: Reinforced insulation meets EN 50178 for industrial control panels. Short-circuit current limitation (<2.8A) prevents wiring damage. SIL 2 certification supports safety-critical applications.

Intelligent Monitoring: DC OK relay contact (SPDT, 24V/2A) provides remote status alerts. LED indicators (input/output/fault) enable rapid diagnostics.

Space-Optimized Installation: Compact DIN-rail form factor saves 40% panel space. Tool-less terminal blocks accept 12–24 AWG wires.

Application Field

The Honeywell FC-PSU-UNI2450U V2.1 secures power for mission-critical automation:

Process Safety Systems: Powers Honeywell Safety Manager PLCs in SIL 2/3 emergency shutdown (ESD) systems for oil refineries.

Pharmaceutical Manufacturing: Provides clean power to hygienic process I/O in GMP-compliant cleanrooms.

Water/Wastewater Treatment: Immune to voltage fluctuations in pump control panels with -25°C cold-start capability.

Food & Beverage: Washdown-resistant operation for packaging lines (NEMA 4X with optional kit).

Mining Operations: Withstands 5g vibration in conveyor control cabinets per IEC 60068-2-6.

Installation and Maintenance

Pre-installation preparation: Verify input voltage compatibility. Ensure DIN-rail thickness (≥1mm) and mounting orientation (vertical ±5°). Maintain ≥25mm clearance for airflow. Ground enclosure via dedicated terminal (≤0.1Ω).

Maintenance recommendations: Monitor output voltage quarterly via test points. Clean ventilation slots annually with dry compressed air. Check terminal torque every 2 years (0.6 N·m). Replace immediately if “FAULT” LED illuminates.
