YOKOGAWA F3PU10-0N AC power supply module
The YOKOGAWA F3PU10-0N is a core AC power supply module designed for the FA-M3 (Free Application Multi-controller) and FA-M3V PLC series.
It serves as the primary power source for the backplane logic, ensuring that the CPU and expansion modules receive a regulated voltage to operate.
1. Introduction
The F3PU10-0N is the standard AC power supply for smaller FA-M3 rack configurations. It is typically installed in the dedicated “Power” slot on the far left of the base module.
While the older F3PU06-0N was widely used, the F3PU10-0N (and its terminal-revision successor, the F3PU10-0S) has become the common standard for 4-slot and 6-slot systems due to its reliability and wide input voltage range.

3. Product Advantages and Features
Universal Input: Operates seamlessly across global power grids (100V to 240V) without manual switching.
Safety & Diagnostics: Includes a FAIL output contact that opens if the 5V DC output drops, allowing the system to trigger an emergency shutdown or alert.
Robust Noise Immunity: Designed to withstand high-voltage spikes ($1500\text{Vp-p}$) typical in industrial environments, ensuring stable CPU operation.
High Efficiency: Low power consumption and natural convection cooling (no fan required), which increases the module’s lifespan.
4. Application Cases
The F3PU10-0N is found in systems where the total power draw of the CPU and I/O does not exceed 2.0A:
Small Machine Automation: Powering 4-slot racks for dedicated machine control (e.g., labeling or sorting).
Remote I/O Stations: Providing power to distributed RIO racks in a larger plant network.
Environment Monitoring: Used in data logging systems for cleanrooms or laboratories.
HVAC Control: Powering local logic controllers in building management systems.

5. Other Models in the Same Series
Depending on the number of slots in your rack and your power source, you may need a different module:
F3PU10-0S: The direct successor to the 0N model. The only major difference is the terminal screw size (M4 instead of M3.5).
F3PU20-0S: High-capacity AC power supply (4.3A) for larger 9-slot and 13-slot racks.
F3PU30-0S: Max-capacity AC power supply (6.0A) for fully populated 16-slot racks.
F3PU16-0N / 0S: DC-input version (24V DC) with 2.0A output.
F3PU36-0S: High-capacity DC-input version (24V DC) with 6.0A output.
Important Note: If you are replacing an F3PU10-0N with an F3PU10-0S, verify your wire terminal size.
The “-0S” uses M4 screws, which may require slightly wider fork or ring terminals than the older “-0N” M3.5 screws.
