Product Overview

The YOKOGAWA NFPW441-50 module functions as a critical Power Supply Unit (PSU), providing the necessary regulated low-voltage DC power to the control system's backplane and all installed modules (CPU, I/O, and communication cards). This essential YOKOGAWA component ensures the stable and reliable operation of the entire control station by converting the high-voltage AC input into the required DC voltages (e.g., 5 V, 24 V). The NFPW441−50 is designed for robust industrial environments and often supports the implementation of a redundant power architecture. The -50 suffix often denotes the specific AC input voltage range and output power capacity.

Detailed Technical Specifications of the NFPW441−50

The YOKOGAWA NFPW441-50 Power Supply Module is designed to operate on wide-ranging AC input voltages, making it versatile for global installation.

Redundancy and Reliability

The NFPW441−50 is typically installed in dedicated slots on the backplane and supports a redundant configuration, allowing for two identical PSUs to share the load and provide a seamless backup in case of failure. This redundancy ensures non-stop operation in critical systems. Additionally, the module incorporates protection mechanisms to safeguard the system against overcurrent, overvoltage, and short circuits.
