Product Description
Product Overview
- The Honeywell FS-PSU-UNI2450U Power Supply is a robust and efficient unit designed to deliver stable DC power for industrial control systems, such as those within Honeywell’s Safety Manager or Experion platforms. Supporting a wide input voltage range of 110-240 V AC, this power supply provides adjustable output voltages of 25 V DC or 28 V DC, with high current capacities and dual overvoltage protection. Certified by TUV, it features compact dimensions, high efficiency, and a derating curve for output current based on temperature, making it suitable for demanding automation environments.
