Description
Honeywell FC-PSU-UNI2450U V1.0 is a UL508-approved switched-mode DC power supply developed to provide stable and efficient power conversion for industrial automation systems. The unit accepts a universal AC input range from 93 to 253 VAC with an operating frequency of 47 to 63 Hz, allowing operation in different power environments. With an efficiency exceeding 85% at 220–240 VAC and over 80% at 110–120 VAC, FC-PSU-UNI2450U V1.0 minimizes energy loss while maintaining dependable performance.

Supporting selectable output voltages of 25 VDC or 28 VDC, Honeywell FC-PSU-UNI2450U V1.0 supplies up to 48 A at 25 VDC or 43 A at 28 VDC, with total output power limited to 1200 W through an integrated current limit feature. Dual built-in over-voltage protection helps satisfy the functional safety requirements of IEC 61508, while ripple and noise remain below 40 mVpp for clean DC power delivery. A hold-up time of 100 ms at full load further improves system stability during temporary input disturbances.

Operational reliability is enhanced through several integrated protection and monitoring functions. FC-PSU-UNI2450U V1.0 includes an under-voltage alarm that activates when the output falls below 22 VDC, a fan alarm, continuous overload and short-circuit protection, an output diode for parallel operation, and an alarm contact rated at 100 mA/30 V. An output adjustment selector switch allows users to select either 25 VDC or 28 VDC according to application requirements.

Maintenance has been simplified with a recessed power switch together with isolated AC and DC connectors. This arrangement allows the power supply to be switched off before disconnecting cables, enabling on-line replacement without generating sparks or voltage spikes on the electrical grid. The AC input uses an IEC 60320 C20 inlet with a retaining clip, while DC output connections employ Phoenix connectors with locking screws supporting conductor sizes from 0.75 mm² to 16 mm².

Honeywell FC-PSU-UNI2450U V1.0 operates within temperatures from -5°C to +70°C and can be mounted either vertically or horizontally. Vertical installation is recommended because convection cooling performs most efficiently when the power and fan input face downward. At least 100 mm of free space should be maintained around the unit to ensure proper airflow and cooling performance. For applications requiring additional electromagnetic noise suppression, the PSU-FLTR2450 common mode filter can be directly installed on FC-PSU-UNI2450U V1.0 without major modifications.
