Product Introduction (No Fluff)

The F3PU10-0N is an AC power supply module for the YOKOGAWA FA-M3 / FA-M3R programmable controller platform. It accepts 100-240 V AC input and provides 5 V DC bus power to the CPU and I/O modules installed in the same base.

This module is sized specifically for 4-slot and 6-slot base modules (F3BU04-0N and F3BU06-0N). For maintenance teams keeping FA-M3 systems running, a verified replacement unit avoids the risk of underpowered racks or mismatched supply ratings when restoring a failed power section.

QA & Testing SOP (Dynamic & Transparent)

Power supplies get checked harder than most modules because a bad unit can take down the entire rack:

1. Visual & authenticity check: Inspect housing, label, terminal block, and solder joints for rework, burn marks, or counterfeit indicators.
2. Terminal & pin inspection: Verify AC input terminals and backplane connector pins for corrosion, looseness, or bent contacts.
3. Bench power-up test: Apply 100-240 V AC on a test bench and confirm clean initialization without fault indicators.
4. Output voltage & ripple check: Measure 5 V DC output under load with a Fluke multimeter or oscilloscope to confirm voltage stability and acceptable ripple.
5. ESD-safe packaging: After testing, the unit is sealed in anti-static shielding with moisture barrier protection for shipment.

Installation Pitfalls & Guide (Engineer to Engineer)

❗ Do notse with -0S. Both are 100-240 V AC power supplies for 4-slot and 6-slot bases, but the suffix indicates different terminal or mounting variants. Always match the exact suffix to your existing base module configuration.

❗ Do not install in a 9/13/16-slot base. The F3PU10-0N is rated for F3BU04-0N and F3BU06-0N bases only. Larger bases require F3PU20, F3PU30, F3PU26, or F3PU36 series modules.

❗ Check total 5 V DC load before powering up. Adding I/O modules can push the rack’s current draw beyond the supply’s capacity. Verify the sum of all module current consumption against the power supply’s rated output.

❗ AC wiring must be secure and grounded. Loose AC terminals or missing chassis ground can cause intermittent resets, noise on the 5 V bus, or safety hazards.

Replacement steps:

1. Pre-install: Confirm base module type, total rack current draw, and AC input voltage.
2. Removal: Disconnect AC power; release the module and withdraw it from the base.
3. Install: Seat the module firmly into the base, verify pin alignment, and secure AC wiring.
4. Power-on test: Restore AC power, verify 5 V DC output, and confirm the CPU and I/O modules initialize normally.

Technical FAQ

What he do? It is a 100-240 V AC power supply module for the YOKOGAWA FA-M3 / FA-M3R PLC, providing 5 V DC bus power to CPU and I/O modules in 4-slot and 6-slot base modules.

What is the differenceen and -0S? Both are AC power supplies for 4-slot and 6-slot FA-M3 bases. The suffix (-0N vs. -0S) indicates different terminal or mounting variants. Always match the suffix to your existing hardware configuration.

Can I use this in a 9-slot or 16-slot base? No. The F3PU10-0N is designed for F3BU04-0N and F3BU06-0N bases only. For 9/13/16-slot bases, use F3PU20-0S, F3PU30-0S, F3PU26-0N, or F3PU36-0S depending on input voltage and current requirements.

Is this module still available from Yokogawa? The FA-M3/FA-M3R platform is a mature product line. New OEM stock may be limited. Surplus and tested units are often the most practical option for maintaining existing installations.

What is the warranty? Surplus and tested units typically carry a 12-month functional warranty. Confirm exact terms at checkout, as condition varies by lot.
