FAQ

Q: Can this module operate outside the rated AC voltage range?
A: Yes, it supports 170–264 V AC, but operation beyond this range may reduce lifetime.

Q: Is the NFPW442‑50 compatible with other Yokogawa modular controllers?
A: It is primarily designed for STARDOM systems but can work with other Yokogawa modules requiring +5.1 V DC input.

Q: What protections are included?
A: Inrush current limiting, overcurrent protection, fuse protection, insulation withstand, and momentary power-failure tolerance.

Q: How does it compare to similar power modules like NFPW442‑100?
A: The NFPW442‑50 offers slightly lower maximum output current (7.8 A vs 15 A) but maintains the same reliability and industrial protections for smaller systems.
