Yokogawa PW482‑10 Power Supply Module

The Yokogawa PW482‑10 is a dedicated rack power supply module for Yokogawa DCS systems. It provides stable DC power for CPU, communication modules and various I/O units inside the DCS cabinet to guarantee reliable operation of the whole control rack.

This module supports redundant power supply configuration and comes with over‑voltage, over‑current and short‑circuit protection. It is widely used as spare replacement for DCS maintenance and upgrade projects in petrochemical, power and other process industries.
