Product Description
The NFPW442-10 is a high-reliability AC-to-DC power supply module for Yokogawa STARDOM FCN and FCJ autonomous controllers. It converts 220–240 V AC input into stabilized DC rails for the controller backplane, processor, and I/O circuits. The module features a dual-output design, providing +5.1 V DC for system logic and +24 V DC for analog field circuits. Designed for mission-critical applications, it supports duplexed redundancy with hot-swap capability, enabling maintenance without interrupting control processes.

Technical FAQ
Q: What happens if the power failure lasts longer than 10 ms?
A: The module will perform a controlled shutdown to protect CPU state and resume operation within 300 ms once stable power is restored.
Q: Is this module suitable for hazardous locations?
A: No, the -10 suffix indicates a standard type without explosion protection. For hazardous areas (Zone 2 / Class I Div 2), select the -E variant.
