Introduction to HONEYWELL FC-PSU-UNI2450U
FC-PSU-UNI2450U Product Overview
The HONEYWELL FC-PSU-UNI2450U is a UL 508-approved switched-mode DC power supply unit, tailored for high reliability and efficiency in industrial automation and safety instrumented systems (SIS). It serves as a core power component that converts a wide range of AC input into stable DC output, delivering continuous and reliable power to critical field devices such as sensors, actuators, and controllers. Equipped with dual over-voltage protection, overload protection, and a fan status monitoring system, this unit ensures stable operation even in harsh industrial environments. It also supports parallel operation for redundancy and features isolated AC/DC connectors for online replacement, seamlessly integrating with Honeywell DCS systems (e.g., PKS, C300) to safeguard the continuity and safety of critical industrial processes.
