ABB SA168 3BSE003389R1 | Legacy Power Supply Module, Surplus

Description

Key Technical Specifications

Product Introduction

The ABB SA168 3BSE003389R1 is a legacy power supply module used in older ABB automation systems. It belongs to the ABB 3BSE-series hardware family and is typically found in maintenance lists for plants running legacy DCS or PLC racks where original power modules must be replaced without migrating the entire system.

Unlike modern AC 800M power supplies such as the SD82x family, the SA168 is not a current catalog product and should be treated as an obsolete spare. Its exact role depends on the host rack architecture, so it should only be procured after confirming the existing system model, slot position, input voltage, and output requirements.

QA/QC Transparency SOP

1. Intake & Origin Verification: Confirm model SA168 and part number 3BSE003389R1 on the label. Photograph serial number, revision, date code, and connector condition.
2. Visual Inspection: Check for burnt components, swollen capacitors, corroded terminals, damaged backplane pins, or cracked housings.
3. Electrical Parameter Tests: Apply rated input voltage in a controlled test setup. Measure output voltage, ripple, and load regulation. Verify over-current and short-circuit protection behavior where applicable.
4. Load & Stability Testing: Run the module under rated or near-rated load for an extended period. Monitor temperature rise, output stability, and alarm/indicator behavior.
5. Final QC & Packaging: Label the unit with verified model, part number, revision, and test results. Seal in anti-static packaging with a test report. Any module with unstable output, excessive ripple, or unknown revision is quarantined.

Field Engineer Gotchas

• Missing datasheet risk. Public documentation for SA168 3BSE003389R1 is limited. Do not guess input/output ratings; read the nameplate first.
• Rack compatibility. This module belongs to a legacy ABB platform and is not interchangeable with AC 800M SD82x power supplies without verification.
• Revision mismatch. Even with the correct part number, different revisions may have different output ratings or connector layouts.
• Backplane pin damage. Legacy power modules often fail at the backplane connector. Inspect pins before installation.
• Hidden degradation. A power supply may show correct no-load voltage but collapse under load. Always test under load before deploying.

Application Scenarios

• Legacy ABB DCS rack maintenance where an original power supply has failed.
• Obsolete PLC system spare-parts provisioning for plants that cannot migrate immediately.
• Refurbishment projects requiring verified legacy ABB power modules.
• Migration planning where existing power architecture must be inventoried before replacement.

FAQ

No. It is considered an obsolete/legacy ABB power supply module and is available mainly as surplus or refurbished stock.

Can I replace it with an AC 800M SD82x power supply?
Not automatically. The belongs to a different legacy platform. Mechanical fit, backplane pinout, voltage ratings, and rack compatibility must all be confirmed.

What are the input and output ratings?
These are not publicly confirmed in available sources. Check the physical nameplate or OEM documentation before installation.

Is this module compatible with S800 I/O racks?
Do not assume compatibility. S800 I/O and AC 800M systems use different power architectures. Verify the host rack type first.

Can it be tested before shipment?
Yes. A proper test should include no-load voltage, loaded output, ripple measurement, and thermal stability.

Do you provide an OEM datasheet?
A verified OEM datasheet for 3BSE003389R1 is not publicly confirmed. Final validation should be done against the physical module label and the existing system documentation.
