TDK FAW05-5R0 5V DC 5A 25W AC-DC Power Supply Module

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The TDK FAW05-5R0 is a compact 25 Watt single-output AC-DC switching power supply designed to deliver precise 5 V DC power at up to 5 A for legacy control racks, distributed control systems (DCS), and marine electronics such as Yokogawa PW502 power modules. It converts universal AC line voltages into clean, low-ripple DC power to maintain system stability across critical industrial backplanes.

Because TDK has officially discontinued the FAW series, sourcing this component as New Surplus is a critical risk-mitigation strategy. Acquiring genuine factory-sealed inventory eliminates the high failure rates associated with aged electrolytic capacitors in used power units, ensuring maximum operational uptime while avoiding expensive engineering redesigns or emergency plant shutdowns.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Execute complete Lock-Out/Tag-Out (LOTO) procedures on the primary AC feeder circuit providing power to the cabinet.
2. Put on an ESD-grounded wrist strap and verify chassis ground integrity.
3. Inspect cabinet wiring tags and photograph existing terminal pinouts, wiring colors, and mounting orientation before disconnecting.

Stage 2: Removal

1. Verify zero energy state across input AC terminals using a calibrated multimeter.
2. Carefully disconnect AC input wires (L, N, PE) and 5 V DC output wiring from the terminal connectors.
3. Loosen retaining screws securing the old power unit to the backplate and gently pull the module straight out to prevent stress on adjacent rack components.

Stage 3: Installation (Clone & Seat)

1. Inspect the New Surplus TDK FAW05-5R0 for intact factory seals and pristine terminal connections.
2. Mount the module securely to the panel using original OEM torque specifications.
3. Wire the AC input and 5 V DC output lines according to manufacturer schematics, ensuring correct polarity (+5 V and Common) to avoid damaging downstream logic boards.

Stage 4: Power-On & Testing

1. Measure insulation resistance between input AC rails and chassis ground before energizing.
2. Restore AC line power and measure the DC output across terminals using a precision DMM to confirm a steady 5.0 V DC reading.
3. Verify that cabinet status indicators and connected controller backplanes power up without diagnostic fault flags.

Firmware/Software Versions & Upgrade Notes

• Firmware Dependency: As a hardware-level analog AC-DC power converter module, the TDK FAW05-5R0 operates without internal software or microcode firmware.
• Compatibility Notes: The unit is directly pin-compatible and electrically equivalent to OEM power assemblies such as the Yokogawa PW502 power unit.
• Hardware Revision Advice: Always cross-reference the physical dimensions and connector pin pitch if swapping into custom third-party enclosures, as generic replacement power units may alter mounting footprints or cooling profiles.

Frequently Asked Questions (FAQ)

Is this TDK FAW05-5R0 module brand new or pulled from used equipment?

This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.

Why is New Surplus priced higher than used or refurbished units available online?

New Surplus inventory guarantees unused electrolytic capacitors and zero operating hours. Refurbished or used power supplies carry degraded internal components that frequently fail under thermal stress. Investing in New Surplus avoids unplanned downtime that can quickly exceed thousands of dollars per hour.

Since TDK has discontinued the FAW series, is this part still reliable?

Yes. Our New Surplus stock has been preserved in ESD-safe, climate-controlled storage. Pre-shipment quality control includes visual verification, insulation testing, and full-load power-on checks to ensure factory-spec voltage regulation.

Can I use this power module as a direct drop-in replacement for a Yokogawa PW502?

Yes. The TDK FAW05-5R0 serves as the internal core power supply block for several legacy system modules, including the Yokogawa PW502 assembly. Form, fit, and electrical output match original OEM specifications.

Does this power supply support hot-swapping while the rack is live?

No. Hot-swapping this unit while AC power is applied poses severe electrical shock risks and can cause voltage spikes that damage sensitive backplane electronics. Always isolate line power completely prior to replacement.

What warranty coverage comes with this New Surplus power module?

Every TDK New Surplus unit includes a full 1-year functional replacement warranty, backed by comprehensive pre-shipment QC test reports and serial number tracking.
