Product Description
The SPW481-13-S1 is a high-reliability AC-to-DC power supply module for Yokogawa CENTUM VP and FIO systems, designed for mission-critical process control. It converts 100–120 V AC input into a regulated DC bus voltage for Field Control Units (FCUs) and I/O expansion racks. The “13” series indicates a hardened module with ISA Standard G3 conformal coating and an extended operating temperature range. The S1 revision represents optimized hardware for improved thermal performance and EMI protection in dense cabinet environments.

Common Technical Questions
Q: What improvements does the S1 hardware revision provide?
A: The S1 revision improves internal components (capacitors, shielding), resulting in higher MTBF and better EMC performance compared to the original SPW481-13.
Q: Can the SPW481-13-S1 replace a standard PW481 module?
A: Yes, it is physically and electrically compatible, but the SPW481-13-S1 is preferable for installations requiring enhanced environmental durability and extended temperature support.
