Description
Core Product Summary
The Yokogawa F3PU10-0N is a standard AC power supply module designed for the FA-M3 Range-Free Multi-Controller system. Engineered to mount directly into dedicated power slots on FA-M3 base modules, this unit converts universal single-phase AC input into a regulated 5 V DC system voltage to power backplane communications, CPU modules, and system I/O cards.
Operating across a broad 100 to 240 V AC nominal supply voltage range (with a total permissible range of 85 to 264 V AC at 50/60 Hz), the module delivers a rated 5 V DC output at up to 2.0 A. Housed in a compact form factor, it provides stable internal logic power while maintaining isolation standards between external utility lines and internal backplane circuitry.

Detailed Product Overview
The Yokogawa F3PU10-0N supplies regulated DC system power required by FA-M3 programmable controllers. It installs into the leftmost dedicated slot of compatible FA-M3 base units, converting incoming AC line voltage down to the 5 V DC level needed by the main backplane. Its 2.0 A current rating is tailored for smaller logic racks containing a main CPU module alongside a selection of digital and analog I/O cards.
Integration into control cabinets is simplified by its compact width of 28.9 mm, preserving DIN-rail or panel space. The module handles power line fluctuations with a wide input tolerance and includes ride-through capability during brief utility voltage drops (up to 20 ms in standard mode). Built-in noise filter circuitry protects sensitive backplane processor buses from high-frequency electromagnetic interference common in industrial environments.

System Compatibility & Integration Requirements
| Item / Dependency | Verified Compatibility or Requirement | Practical Note |
| Compatible Base Modules | Yokogawa F3BU04-0N (4-slot) and F3BU06-0N (6-slot) base units | Sized specifically for 4-slot and 6-slot base configurations. Larger racks require higher-capacity power supply units. |
| Output Current Capacity | 2.0 A total at 5 V DC | Total 5 V DC backplane current consumption of all installed CPU and I/O modules must not exceed 2.0 A. |
| Terminal Wiring | Screw terminal block for AC power connection | Accepts single-phase AC input lines (L, N) along with a direct connection to Frame Ground (FG). |
| Grounding Requirement | Frame Ground (FG) terminal | FG must be connected to a low-impedance protective earth ground for safe operation and noise rejection. |
