📘 Product Overview
Model: A2PW503-S0002
Product Type: 24V DC Output Power Supply Module
Brand: Yokogawa
Series: A2PW Series (for DCS and automation control systems)
The Yokogawa A2PW503-S0002 is an industrial-grade 24V DC power supply module designed to deliver stable and reliable power to distributed control systems (DCS). It is a key component used in CENTUM VP and other control platforms, converting 100–240V AC input into a regulated 24V DC output to support I/O modules, CPUs, interface cards, and communication processors.
The “-S0002” suffix typically indicates a version with specific build options, such as environmental specifications, mounting style, or enhanced reliability features. This unit is engineered for robust operation in industrial environments and supports redundancy configurations for mission-critical applications.
