Honeywell FC-PSU-UNI2450U Universal Power Supply Unit 24VDC 50A

Product Description

The FC-PSU-UNI2450U (FC-PSU-UNI2450U) is a high-capacity, industrial-grade Universal Power Supply Unit specifically engineered for Honeywell’s Safety Manager, Fail Safe Controller (FSC), and Experion PKS platforms. This module is a critical component for high-integrity safety systems, converting universal AC input into a stabilized 25 Vdc or 28 Vdc output to drive safety controllers, I/O racks, and field instrumentation.

Unlike standard power units, the FC-PSU-UNI2450U (FC-PSU-UNI2450U) is designed for mission-critical reliability. It features dual overvoltage protection and an exceptional hold-up time of 100 ms, ensuring the safety controller remains operational during brief power sags or switchover events. The unit’s robust thermal management and Class I Division 2 certification allow for continuous operation in the harsh environments typically found in petrochemical, upstream oil and gas, and heavy power generation facilities.
