Product Overview

The Yokogawa F3PU10-0S is a standard AC Power Supply Module for the FA-M3 PLC system. It is designed to convert wide-range AC input (100–240 V) into a regulated 5 V DC backplane supply, ensuring stable operation of the CPU, I/O modules, and communication modules inside the FA-M3 rack system.

This module is the “S-type” revision of the F3PU10 series, where the internal electrical design remains similar to the F3PU10-0N, but with updated terminal and mechanical configuration for improved installation compatibility.

Technical Specifications

Function and Working Principle

The F3PU10-0S functions as the primary power conversion unit in FA-M3 PLC systems.

Working Principle

1. AC input (100–240 V) is supplied to the module
2. Internal rectifier converts AC → DC
3. Switching regulator stabilizes output to 5 V DC
4. Regulated power is distributed through the FA-M3 backplane
5. All connected modules receive stable operating voltage
