ABB identifies 3BSE003390R1 as the SA167 Power Supply Unit, specified for AC 115 V input and DC 24 V, 25 A output. ABB’s published product data also gives a net weight of 26.6 kg and lists spare fuse 5672827-15.

Module 3: Technical Intro & Downtime Impact

When an Advant OCS power supply drops out, the failure can propagate well beyond the power-conversion stage. Controller racks, I/O equipment, distribution hardware, and associated field-control functions can lose their required DC supply at once. The ABB SA167 3BSE003390R1 is the 115 VAC version of the SA16x power-supply family, converting the incoming AC supply to a nominal 24 VDC at 25 A for legacy Advant installations. ABB documentation identifies the unit as an Advant Master component and lists it as part of several SA167 power-supply kits used with Advant Controller and I/O configurations.

For emergency maintenance, the key numbers are straightforward: 120 VAC-class input, 24 VDC output, 25 A maximum output, with published physical dimensions of 482 mm × 177 mm × 255 mm and a 26.6 kg net weight. The older Advant documentation reports approximately 705 W mains load and about 85% typical efficiency for the 25 A SA1xx supply class. That makes replacement sizing a cabinet-level exercise rather than a simple “24 V supply” substitution. A modern DIN-rail PSU with the same nominal voltage is not automatically an electrically or mechanically equivalent replacement.

Module 4: Dynamic Emergency Swap & Configuration Guide

1. Pre-Swap Prep — De-Energize and Verify the Supply Path

Follow the plant LOTO procedure and isolate the upstream AC feed before opening the cabinet. Verify absence of hazardous voltage at the SA167 input terminals with an appropriately rated meter. Record the incoming line configuration, output wiring polarity, grounding arrangement, fuse condition, and which Advant controller/I/O racks are supplied by this unit. Check the nameplate carefully for SA167 / 3BSE003390R1 before removing anything.

Keep the replacement supported mechanically. At roughly 26.6 kg, this is not a one-hand electronics swap.

2. Removal — Disconnect the Cabinet-Wired Power Assembly

After confirming the AC supply is isolated, document each terminal and cable before disconnection. Remove the input AC conductors, DC output conductors, protective-earth connection, and any associated distribution connections according to the original cabinet drawing. Release the assembly’s cabinet mounting hardware and support the chassis while removing the final fasteners. Avoid disturbing adjacent Advant distribution components unless they are explicitly part of the replacement scope.

3. Installation & Configuration — Match Voltage, Current, and Distribution

Mount the replacement in the original cabinet position and restore the protective-earth connection first. Reconnect the AC input and 24 VDC output according to the original wiring schedule, observing polarity. Confirm that the downstream load is actually intended for the ‘s 24 VDC / 25 A output. ABB lists this supply as being incorporated into multiple SA167K kits for Advant controllers, subracks, and redundant configurations, so the exact cabinet arrangement matters.

Do not substitute the SA168 merely because its model family looks similar. ABB’s product data distinguishes as the AC 115 V version, while SA168 is associated with the AC 230 V version.

4. Power-On Self-Test (POST) — Measure Before Loading the Rack

With all connections checked, restore the upstream AC supply under controlled conditions. Measure the DC output before reconnecting or fully loading the downstream equipment where the cabinet procedure permits. Confirm a stable approximately 24 VDC output and inspect for abnormal heat, odor, audible arcing, or repeated fuse operation.

Then energize the connected Advant equipment and verify controller startup, I/O power status, and system diagnostics. If the 15 A fuse opens again, do not repeatedly replace it; ABB specifically identifies 5672827-15 as the associated spare fuse reference, while the repeated failure may indicate a downstream fault rather than a defective fuse.

Module 5: Quality Assurance & Testing SOP

Every available ABB / 3BSE003390R1 should undergo a documented electrical and mechanical acceptance process before shipment:

1. OEM anti-counterfeit visual inspection — verify ABB markings, designation, 3BSE003390R1 product identification, label quality, enclosure construction, terminals, mounting hardware, and manufacturing markings.
2. Part-number reconciliation — compare the physical nameplate with / 3BSE003390R1 and the customer’s Advant OCS cabinet BOM.
3. Mechanical inspection — verify mounting points, enclosure integrity, terminal condition, cooling openings, internal contamination, and signs of overheating or component replacement.
4. Fuse verification — inspect the installed fuse and confirm the correct ABB-associated spare reference 5672827-15 is documented for maintenance use.
5. Insulation and grounding checks — perform appropriate insulation-resistance and protective-earth continuity tests according to the applicable safety procedure and test voltage for this power-supply assembly.
6. Controlled AC input test — apply the specified 115/120 VAC-class input through an appropriately protected test source and monitor input behavior.
7. DC output verification — verify approximately 24 VDC output under no-load and controlled-load conditions.
8. Load test — progressively load the 24 VDC output toward the documented 25 A rating while recording output voltage, input current, temperature rise, and abnormal noise.
9. Protection test — verify that the supply responds appropriately to controlled overload/short-circuit test conditions where the laboratory setup and safety controls permit.
10. Thermal observation — monitor the enclosure and internal cooling behavior during sustained loading. Older cabinet supplies can behave differently when installed in confined or poorly ventilated enclosures.
11. Advant system simulation — connect the supply to a compatible test distribution arrangement and verify stable controller/I/O power delivery.
12. Final QA record — retain nameplate photographs, measured input/output values, load percentage, fuse identification, insulation results, thermal observations, and final packaging photographs.

The published ABB dimensions are substantial—482 × 177 × 255 mm—and the net weight is 26.6 kg. Packaging must therefore protect both the enclosure and the mounting hardware during shipment.

Module 6: Maintenance & Reliability FAQ

Is the ABB 3BSE003390R1 a direct drop-in replacement?

It can be a direct replacement only when the existing unit is the same / 3BSE003390R1 configuration and the cabinet wiring and downstream load match. Confirm the input voltage, 24 VDC distribution arrangement, mounting dimensions, fuse arrangement, and Advant system configuration before installation. ABB’s documentation shows that is used in several different power-supply kits, including basic, expansion, and redundant arrangements.

Is it safe to hot-swap the while the Advant system is running?

No. This is a cabinet AC/DC power supply, not a plug-in hot-swappable I/O assembly. The input circuit carries hazardous AC voltage, and disconnecting the DC supply can remove power from the connected controller or I/O racks. Use the approved plant shutdown, isolation, and LOTO procedure before replacement.

Will replacing the affect my current controller program?

The is a power-supply unit, not the Advant application controller itself. Replacing it does not normally constitute a controller-program replacement. The real risk is power interruption: an uncontrolled outage can affect volatile states, connected equipment, or an already marginal controller system. Maintain current controller/database backups and ensure the downstream system has a documented controlled restart procedure.

What should I verify before ordering an emergency spare?

Start with the complete identification: ABB , 3BSE003390R1. Then confirm 115/120 VAC input, 24 VDC output, 25 A capacity, cabinet dimensions, terminal arrangement, and whether your installation is part of an SA167K basic, expansion, or redundant configuration. Do not substitute the 230 VAC SA168 simply because the physical family is similar.

What are the warranty terms if the unit fails after installation?

Warranty depends on the supplying party and the purchased condition of the unit. Before shipment, obtain written confirmation of the warranty period, DOA coverage, testing performed, and return procedure. Retain the pre-shipment QA record and commissioning measurements; for an older Advant power supply, those records help distinguish an internal supply failure from an overloaded downstream distribution circuit or cabinet-wiring problem.
