PW481-10 YOKOGAWA Product Features
Highly stable power output: High precision regulation, low ripple and low fluctuation. Filters grid voltage variation and electrical noise to supply clean power for precision DCS and SIS hardware and prevent control failure caused by power abnormality.
Multi-layer safety protection: Integrated overvoltage, overcurrent, short-circuit and overtemperature protection with automatic cut-off, protecting backend CPU and I/O cards from burnout.
Redundant uninterrupted power supply: Hot parallel redundancy. When one unit fails, backup module takes over seamlessly without power loss or system shutdown for continuous production.
Strong environmental adaptability: Wide temperature design, high temperature resistance, moisture-proof and anti-EMI, stable long-term operation in enclosed control cabinets with high interference.
High compatibility: Custom designed for Yokogawa CENTUM VP and ProSafe-RS systems, fully compatible with matched CPU, I/O and communication cards, plug-and-play.
Simple maintenance: Compact modular design, hot-swap installation. Built-in running and fault LED indicators for quick status check and fault diagnosis.
