Product Description
The PW481-50-S2 is a compact, high-efficiency AC-to-DC power conversion module designed for the Yokogawa CENTUM VP control system. It converts 100–120 V AC input into regulated DC bus voltages required by Field Control Units (FCUs) and associated I/O nodes. The “50” designation identifies this as a standard type (non-explosion-proof) module, while the “S2” revision represents an updated hardware design optimized for thermal management and extended operational longevity. Despite its slim and lightweight profile, the module delivers industrial-grade stability for continuous 24/7 process automation.

-
Optimized S2 hardware: Minor component updates improve thermal performance and module longevity while remaining backward compatible.
Technical FAQ
Q: What does the “S2” suffix indicate?
A: The “S2” identifies a hardware revision level. Revisions typically include minor component improvements that increase MTBF and thermal stability while maintaining full backward compatibility with previous PW481-50 modules.
Q: Can the PW481-50-S2 be used in 220–240 V AC systems?
A: No. The PW481-50-S2 is strictly rated for 100–120 V AC. For 220–240 V AC applications, the PW482 series should be used to avoid hardware damage.
